Hesionura augeneri Goniadella Bobretzkii, and Parapodrilus psammophilus (Annelida, Polychaeta) : new to the Netherlands
Provedor de dados: 16
Autores: Wolff, W.J.; Stegenga, H.
INTRODUCTION AND METHODS During an investigation of distribution and ecology of the Archiannelida of the estuarine area of the rivers Rhine, Meuse and Scheldt in the southwestern part of The Netherlands, three species of polychaetes new to the Dutch fauna were found. Because these species have not been reported very frequently from other localities, the finds are described in some detail. The first two species were found in samples taken with a o.i m2 Van Veengrab; the last one originated from a core sample taken in the beach. After collecting the samples have been treated in the way described by Boaden (1963).  RESULTS AND DISCUSSION Hesionura augeneri (Friedrich, 1937) (fig. 2) This species was found at two localities in the coastal water (fig. 1) at...

On a remarkable polynoid-worm Weberia pustulata nov. gen. nov. spec. from the Malayan Abyss
Provedor de dados: 16
Autores: Horst, R.
At the Stations 45 and 314, north off Soembawa, in a depth of 694 and 794 m, the Siboga-expedition dredged three specimens of Polynoïnae that cannot be identified with any species, hitherto described. Unfortunately they are somewhat incomplete, for the elytra as well as most of the cirri are absent. One of the specimens, a female containing ripe eggs, measures nearly 20 mm. in length and has about 40 segments. The head is rounded, broader as long, prolonged anteriorly into the two stout basal joints of the lateral antennae, that are nearly as long as the head, whereas their distal part is only a trifle longer; the species therefore belongs to the group of Lepidonotidae 1). From the middle of the head a large basal joint of the tentacle arises, but its...

Een Heteronereis-vorm van Nereis succinea Leuck
Provedor de dados: 16
Autores: Horst, R.
Te midden van een tiental exemplaren van Nereis succinea Leuck., door dr. Redeke gedregd in de Zuiderzee, boven Enkhuizen, 15 Juni 1921, trof ik een geslachtsrijp ♂ aan, in heteronereis-toestand. Het exemplaar heeft een lengte van circa 30 mm., maar is niet geheel compleet. De oogen zijn vergroot en de bewapening van de slurp is normaal; alleen ontbreken de paragnathen van groep V. Slechts de voetjes van het middengedeelte van het lichaam vertoonen een epitoke wijziging. Deze begint met het 15e parapodium en strekt zich uit tot het 52e segment; de achterste parapodia stemmen geheel overeen met die van den atoken vorm (loc. cit. p. 146, fig. 3). Zooals gewoonlijk is de dorsale cirrus van de voorste 7 segmenten aan de basis aangezwollen. Bij het epitoke...

Three species of Microphthalmus (Polychaeta) new to The Netherlands
Provedor de dados: 16
Autores: Wolff, W.J.
INTRODUCTION The excellent monograph by Westheide (1967) of the hesionid genera Hesionides and Microphthalmus provided the means to study these genera in The Netherlands. Until now no species belonging to either of these genera have been recorded from this country. Nevertheless, several species of Microphthalmus were found during our ecological studies on the polychaetes of the estuarine area of the rivers Rhine, Meuse, and Scheldt. One of these species, M. fragilis Bobretzky, was so far only known from the Mediterranean and the Black Sea. In the present paper three species are recorded and described. The positions of the localities where these species were found are shown on the map (fig. 1). Ecological data will be published later. Acknowledgements are...

Janua (Dexiospira) Brasilliensis (Grube) (Polychaeta: Spirorbidae) : a new record from the South-West Netherlands
Provedor de dados: 16
Autores: Critchley, A.T.; Thorp, C.H.
A new record in the distribution of the immigrant spirorbid Janua (Dexiospira) brasiliensis is reported from Dutch waters. This is only the second European locality for the serpulid worm, otherwise known from warmer latitudes. J. (D.) brasiliensis (Grube) was found associated with the marine angiosperm Zostera marina L. and the exotic brown alga Sargassum muticum (Yendo) Fensholt, within the protected environment of a saline canal in the south-west Netherlands.

Remarks on the subclass Udonellida (Monogenea), with description of a new species
Provedor de dados: 16
Autores: Land, J. van der.
INTRODUCTION Flatworms living as commensals on parasitic copepods from marine fishes were known already as- early as 1835, when Johnston described Udonella caligorum from Caligus spec., a parasite of Hippoglossus hippoglossus (L.). Since then a number of similar genera and species have been described, but none of these is clearly different from Udonella caligorum, as far as can be judged from the descriptions. Therefore only one valid species is recognized by most modern authors (Price, 1938; Sproston, 1946; Ivanov, 1952b). Calinella ophiodontis Kay, 1945, a species not listed by these authors, probably is another synonym to be added to the long list, but Kay's material should be re-examined before a final decision can be made. In Yamaguti's compilation...

Die Gattung Opisthodonta Langerhans (Syllidae, Polychaeta): Wiederbeschreibung von O. Morena Langerhans Aus dem Westlichen Mittelmeer und aus dem roten meer und von O. Pterochaeta Southern, Neufund in der Nordsee vor der Niederländischen Küste
Provedor de dados: 16
Autores: Hartmann-Schröder, G.
Ophistodonta Langerhans ist die einzige Gattung der Unter familie Eusyllinae, bei der der Pharynx-Zahn auf der hinteren Hälfte des Pharynx liegt. Bis 1954 war die von Langerhans (1879) errichtete Gattung nur durch zwei Arten mit je einem Exemplar bekannt. Von diesen beiden Exemplaren existiert sehr wahrscheinlich nur noch der Holotypus von O. pterochaeta, während die Typusart, O. morena, verschollen ist; jedenfalls ist er in den zoologischen Sammlungen der Universität Hamburg, der Humboldt-Universität in Ost-Berlin und des Senkenberg-Museums nicht vorhanden. 1954 fand Pérès im westlichen Mittelmeer bei Marseille einen Eusyllinen mit einem weit hinten liegenden Pharynx-Zahn, den er mit Zögern der nur sehr kurz beschriebenen Opisthodonta morena von...

Gastrolecithus planus (Linton) (Cestoda, Tetraphyllidea) parasitizing Cetorhinus maximus (Gunnerus) (Elasmobranchii) from the North Sea
Provedor de dados: 16
Autores: Land, J. van der.
INTRODUCTION In 1889 Van Beneden described a new tetraphyllid cestode, Dinobothrium septaria, for which he erected a new genus. It was peculiar in having a rather small body with a very large scolex, the largest of all tapeworm holdfasts. Since then a small number of other species of Dinobothrium have been described (for two of them new genera were proposed, viz. Gastrolecithus Yamaguti, 1952 and Reesium Euzet, 1955). They have only been found in large sharks, both in preying and in plankton feeding species. Mola (1907) was the first investigator who found such a tapeworm in the Basking Shark, Cetorhinus maximus (Gunnerus). Euzet (1955) has tried to elucidate the remarkable and confused history of these animals. He recognized three genera and only three...

Alkmaria romijni n. g. n. sp. Een Terebellide. Eenigen tijd geleden ontving ik van Dr. Romijn, die bezig is met een onderzoek van de Oligochaetidae der binnenwateren van Nederland, een objectglaasje, bevattende drie kleine Anneliden uit het Alkmaarder meer, door hem verzameld in December 1914. Daar in de achterste segmenten uncini zichtbaar waren, besloot ik daaruit, dat de wormpjes jeugdige toestanden van een Terebellide moesten representeeren. Zij bezitten een koplob, van twee ronde oogvlekken voorzien, gevolgd door circa 20 lichaamsegmenten; het voorste van deze draagt twee cirrusachtige kieuwaanhangsels, terwijl de 12 volgende segmenten aan de dorsale zijde een paar bundels haarborsten vertoonen en van af het 4e borsteldragende segment tori uncinigeri...

On a remarquable fresh-water Polychaete "Nereis nouhuysi" from the East-Indies
Provedor de dados: 16
Autores: Horst, R.
In the year 1905 Mr. J. W. van Nouhuys presented to our Museum some Nereis-specimens, collected in the Miha at the South-coast of the isle of Taliaboe, at a distance of two hours from the mouth of the river, that moreover was shut off by a bank of gravel 1). There are eleven specimens, ten females and one male, all mature and in the Heteronereisform. They are characteristically marked; in the median body-region each segment shows on it dorsal side a transverse, black band, narrow in the piddle and growing broader laterally, on the base of the parapodia. Two black spots occur on the dorsal side of each parapodium, whereas the dorsal ligule is also black coloured. Ventrally the segments show a similar marking; however on the base of the parapodium there...

Searching for cryptic species in Erpobdella octoculata (L.) (Hirudinea: Clitellata): discordance between the results of genetic analysis and cross-breeding experiments
Provedor de dados: 16
Autores: Koperski, P.; Milanowski, R.; Krzyk, A.
The main aim of this study was to reveal reproduction barriers and potentially cryptic radiation within the very common and morphologically variable leech species - Erpobdella octoculata (L., 1758). The differences in reproductive success of the morphological forms were compared experimentally. The data based on the results of field sampling and analysis of ITS and COI sequences is also presented. The results of the analysis of DNA sequences clearly show lack of reproduction barriers between the analysed morphological forms. Subtle differences in DNA sequences between individuals, found with the use of the arbitrary primers method, seem to be related mainly to geographical distance between sub-populations. On the basis of these results, E. octoculata...

Paralacydonia weberi n. sp. Among some Glyceridae, dredged by the Siboga-expedition at Stat. 52, south off Flores at a depth of 959 M., I met with five specimens of a Polychaet, which must be ranged among the genus Paralacydonia. This rare genus was based by Fauvel in 1913 1) on three specimens of a worm (Paralacydonia paradoxa) that holds an intermediary place between the Phyllodocidae and Nephthyidae and was found in the Mediterranean sea, south of Monaco, at a depth of about 50 M. The prostomium is conical and provided at its distal end with four bi-annular antennae; the buccal segment is without appendages. The first setigerous segment bears uniramous parapodia, whereas the following parapodia are biramous; the two lobes are separated from each other...

A note on the occurrence of Oligochoerus limnophilus Ax &amp; Dörjes (Turbellaria, Acoela) in freshwater habitats in the Netherlands
Provedor de dados: 16
Autores: Dörjes, J.; Young, J.O.
The only hitherto known freshwater acoelan, Oligochoerus limnophilus, has been fully described by Ax &amp; Dörjes (1966). It has been recorded from habitats of different European rivers: Elbe, Ilmenau, Lahn, Main, Mosel and Donau (Kothé, 1961, 1962; Kothé &amp; Sturz, 1963; An der Lan, 1964) where it prefers to settle on artificial stone embankments and is absent from typical lenitic regions and in river parts with a high organic pollution. The species has also been recorded from irrigation canals of rice fields in the Camargue (leg. U. Graefe). Ax &amp; Dörjes (1966) suppose that O. limnophilus emigrated during postglacial periods out of the ponto-caspian area into their new environments because all the other species of the genus have been found in the...

Of this species several specimens were collected in Table bay, where they were found for the first time by Schmarda 2) and afterwards met with by Willey 3). Unfortunately the description of the species is rather short and incomplete and the synonimy somewhat dubious; therefore I think it not superfluous to give a detailed account of them, especially while an epitocous male was among them. The specimens are rather small, measuring about 30 mm. in length, whereas the number of segments amounts to 70.

A review of the family of Hesionidae with a description of two new species
Provedor de dados: 16

Occupied with the examination of Hesionidae from the Dutch Eastand West-Indies I found not only, that some genera of this family are described under several different names, but also, as already stated by Webster and Benedict, that the genera seem to be badly confused 1); Leocrates Kbg. f. i. is identical with Lamprophaës Gr. and Tyrrhena Clap., and Podarke pallida was ranged by Claparède among the genus Oxydromus whereas Podarke angustifrons according to Grube belongs to the genus Irma. Partly this might be ascribed to the circumstance, that sometimes not full-grown specimens were described, partly to the fact that the cephalic appendages were overlooked, either in consequence of their minute dimension or because they were fallen off.

The Genus Diporochaeta (Oligochaeta Megascolecidae) in Queensland
Provedor de dados: 16
Autores: Jamieson, B.G.M.
Perionychella is reassigned to Diporochaeta as a junior synonym. 9 new species are added to the 8 previously known Queensland species of Diporochaeta, all of which are redescribed, bringing the generic total for Australia to 77 named species. Distribution of the genus is disjunct, the Queensland records being restricted to the northeast, between latitudes 15° and 19°S, with the exception of a single morphologically very isolated species in the Bunya Mountains of southeast Queensland. The remainder of the genus occurs in Tasmania, Victoria, the Australian Alps in southern New South Wales and, a few species, in New Zealand. The genus is redefined and a key to Queensland species provided.

On a new genus of Aphroditidae from the Netherlands' East-Indies
Provedor de dados: 16
Autores: Horst, R.
At the Stations 49a and 260 the Siboga-Expedition collected two specimens of Aphroditidae, that, though agreeing in their main characters with Hermione and Laetmonice, in my opinion cannot be ranged in these genera on account of the quite different shape of their dorsal bristles; therefore the new genus Halogenia may be proposed for them. Halogenia arenifera n. sp. Siboga-expedition, Stat. 49a, Sapeh-strait, depth of 69 M. The body of the unique specimen is ellipsoidal, long 12 mm., broad 7 mm.; the number of its segments is about 30. Its ventral side is rough, densely beset with small tubercles, whereas the dorsum is entirely covered with sand-grains, that are adhering to the elytra. No dorsal felt could be detected. The parapodia are slender, conical,...

Dr Jacob van der Land, marine biologist extraordinary
Provedor de dados: 16
Autores: Bruggen, A.C. van.
This contribution is an attempt to sketch the life and works of Dr Jacob van der Land, curator of worms and chief marine biologist of the National Museum of Natural History, on the occasion of his official retirement. Born in 1935, Jacob van der Land read biology at Leiden University (1958-1964), where he obtained his Ph.D. in 1970 on a treatise on the Priapulida under the supervision of Prof. Dr L.D. Brongersma. In 1964 he was appointed curator of worms in the museum. Later on he took over leadership of the invertebrate section (excluding insects) of the museum and was also placed in charge of all marine research. Initially, Van der Land organized field trips for biology students of Leiden University to Scandinavia, who were able to sample seagoing...

On new and little-known species of Polynoinae from the Netherlands' East-Indies
Provedor de dados: 16
Autores: Horst, R.
Our knowledge of the Aphroditidae from the Malay-Archipelago hitherto was very scanty and considering the great variety of those worms in neighboring seas — Grube from the Philippines 1) mentioned 27 and Potts from the Indian Ocean 31 species 2) — it could be expected that a thorough examination of this region, as done by the Siboga-expedition, should reveal us many new and interesting form; in these expectations we are not disappointed. Two remarkable species viz. Lepidasthenia sibogae and Eulepis malayana, besides three species of Psammolyce are already mentioned before 3); in the present paper we wish to confine ourselves to the subfamily of the Polynoïnae. Only six representatives of this group hitherto are mentioned from Amboina, Borneo, Ceram and...

On the identity and nomenclature of „Pectinaria Belgica (Pallas, 1766)" (Polychaeta, Amphictenidae)
Provedor de dados: 16
Autores: Lucas, J.A.W.; Holthuis, L.B.
In most Dutch scientific and popular books dealing with Polychaeta, the common amphictenid of the Dutch North Sea shore is indicated with the name Pectinaria belgica (Pallas, 1766). In preparing a revision of the Dutch Polychaeta, one of us (J. A. W. L.) studied the extensive collections of Dutch representatives of the family Amphictenidae present in the Rijksmuseum van Natuurlijke Historie at Leiden and the Zoological Museum at Amsterdam, as well as newly collected material from the Dutch beaches. Comparing these specimens with the account by Fauvel (1927:218225) of the Amphictenidae in the Faune de France, all of the Dutch specimens (with the single exception of a specimen of Pectinaria (Amphictene) auricoma collected in the former Zuiderzee) proved to...

Notes on Microturbellaria from freshwater habitats in the Netherlands
Provedor de dados: 16
Autores: Land, J. van der.
INTRODUCTION Freshwater microturbellaria of the Netherlands were studied already by De Man (1874). Since then this subject has not received much attention and much faunistic research remains to be done on this large and interesting group. The present paper deals with material from distribution mains for drinking water in the South and the West of the Netherlands and from a canal in the city of Leiden. A new species of Microdalyellia is described.  MATERIAL AND METHODS The material was taken from the following samples: Sample no. 150. Leiden, Zoeterwoudse Singel (canal), near Koepoortsbrug. Between vegetation (Glyceria); decaying vegetable debris, mainly Glyceria and Aesculus leaves; 10-15 cm deep; temperature above 50 C (there was no ice in the second half...

Marenzelleria viridis (Verril, 1873) (Polychaeta: Spionidae) : a new record from the Ems Estuary (The Netherlands / Federal Republic of Germany)
Provedor de dados: 16
Autores: Essink, K.; Kleef, H.L.
A new record of the North American spionid polychaete Marenzelleria viridis (Verril, 1873) is reported from the Ems Estuary. The species was first found in 1983. From 1983 to 1986 densities increased to a few thousands per m2 while densities of another polychaete, Nereis diversicolor decreased. Juveniles showed peak densities of c. 19000 m2 in muddy sediments. Adults preferred sandy sediments. In Europe M. viridis was recorded recently also in other estuaries: Tay and Forth (Scotland), Weser and Elbe (Fed. Rep. of Germany). There is no reliable clue to the cause of its appearance in North Sea estuaries.

Anatomical and morphometric analysis of a new species of Leitoscoloplos (Annelida: Orbiniidae) with numerous stomach papillae, from the Gulf of California, Eastern Pacific
Provedor de dados: 16
Autores: Hernández-Alcántara, P.; Solís-Weiss, V.
from the continental shelf of the Gulf of California lacking thoracic neuropodial hooks confirmed that a new species, Leitoscoloplos multipapillatus, described herein, is present along with Leitoscoloplos panamensis (Monro. 1933), already recorded there. The new species is closely related to L. panamensis, but can be clearly separated from this, and all other species of Leitoscoloplos, by the unique presence of up to 14 stomach papillae per chaetiger. A third taxon was identified, Leitoscoloplos sp., which is morphologically indistinguishable from L. panamensis, except for the presence of 1-2 stomach papillae on 1-2 segments, a feature that although important was not considered significant enough to erect a new species. Morphometric analyses between the...

On the supposed identity of Bathynoë nodulosus Ditl. and Weberia pustulata Horst
Provedor de dados: 16
Autores: Horst, R.
In December 1915 I published a preliminary account of a rare Polynoidworm, Weberia pustulata, dredged by the Siboga Expedition in a considerable depth in the Malayan Archipelago, at the stations 45 and 314, north off Soembawa 1). The species is especially characterized by the total absence of the eyes as well as of the ventral cirri, except in the first setigerous segment; moreover it lacks the notopodial fascicle, whereas the neuropodial one is represented by four hook-shaped setae. Some time ago Hjalmar Ditlevsen kindly forwarded to me the 1st part of his account of the Annelids of the Danish Ingolf-Expedition 2). In this paper I met with the description of a Polynoid-worm, Bathynoë nodulosus, dredged at great depth in the Atlantic Ocean (south off...

Distinguishing the genera Apomatus Philippi, 1844 and Protula Risso, 1826 (Polychaeta: Serpulidae). A further Plea for a Methodical approach to Serpulid Taxonomy
Provedor de dados: 16
Autores: Hove, H.A. Ten; Pantus, F.J.A.
Ventral thoracic bloodvessel-patterns were defined in a random sample of 152 living specimens of the Apomatus/Protula- complex. Two main patterns and a derived one could be recognized. Eight characters, often used in Serpulid taxonomy and retraceable in preserved material, were determined too: e.g. presence or absence of an operculum and pattern of thoracic setae. These parameters were correlated to the vascular patterns. It was shown that (a) all operculate specimens possess a vascular system of one main pattern; 86% of those closely studied have "Apomatus-setae" at least from setiger 4 onwards; all have radioles with paired rows of compound eyespots. (b) The non-operculate specimens generally possess the other main vascular pattern; the thorax often has...

On a new Aphrodite-species (Aphrod. roulei) from the North Atlantic

Autores: Horst, R.
Among the Annelids of the Leiden Museum I met with two specimens of the genus Aphrodite from the North Atlantic 1), purchased some years ago from the late Mr. G. A. Frank, the well-known dealer in natural objects. They agree with Aphrod. perarmata Roule 2), collected by the "Talisman" in the middle Atlantic (Los Pilones), in the presence of hooked ventral bristles, but cannot be identified with that species. The largest specimen has a length of about 60 mm., whereas it greatest breadth is 30 mm.; the number of its segments amounts to 36. The body has an elongated ellipsoidal shape, with a rather acuminate anal end, while anteriorly it is hardly narrowed. Its ventral side has the appearance of shagreen, being densely beset with small, globular papillae, and...

Genetics and morphology of the genus Tritetrabdella (Hirudinea, Haemadipsidae) from the mountainous rain forests of Sabah, Borneo, reveal a new species with two new subspecies
Provedor de dados: 16
Autores: Kappes, H.
Blood-feeding terrestrial leeches of the family Haemadipsidae are a notorious part of the invertebrate diversity in Asian and Australian rain forests. All hitherto published records of terrestrial leeches of Borneo belong to the genus Haemadipsa. Here, a second, poorly known haemadipsid genus is reported from Mount Kinabalu and Crocker Range National Park. The individuals were barcoded and compared to sequences available in GenBank. The results show that the genus Tritetrabdella has representatives in the Indochinese and the Sundaic bioregions. All six specimens from Borneo are from a single new Tritetrabdella lineage, T. kinabaluensis spec. nov. Within the Bornean lineage, two groups differing 4-5% in the COI barcoding sequence were identified. Because 1)...

On some species of the oriental earthworm genus Pheretima Kinberg, 1867
Provedor de dados: 16
Autores: Gates, G.E.
Pheretima long has been known to have more species than any other oligochaete genus though no one has yet been in a position to determine how many of them have any real claim to recognition even as old-fashioned museum taxa. Intrageneric relationships are unknown primarily because somatic anatomy was derogated in the classical system of the Oligochaeta. Accordingly, if one wishes to learn whether any specimen at hand is of a known or undescribed taxon it is necessary, first of all, to check through appropriate portions of a 16-page table in Michaelsen's monograph (1900) where species are grouped according to location of the spermathecal pores. If identification is impossible, as often must be the case, a laborious search through the literature of the last...

Potato cyst nematodes, G. rostochiensis and G. pallida, are the most economically important nematode pests of potatoes worldwide and are subject to strict quarantine regulations in many countries. Globodera ellingtonae was recently described from Oregon (USA), with its host-plant in the field being still unknown. Roots of Andean potatoes from the North of Argentina have been found attacked by this nematode, providing further evidence that this is a potato cyst nematode species, along with G. pallida and G. rostochiensis. New information about morphological, biological and molecular aspects of G. ellingtonae is provided for diagnostic purposes. The Argentine population showed morphological differences from specimens from Oregon; therefore, new diagnostic...

Deze worm, het eerst waargenomen in den mond van de Thames, de Liffey en andere rivieren in Engeland, werd door dr. G. Romijn op verschillende plaatsen in N. Holland verzameld: in het Noordhollandsch kanaal bij Schoorldam en in kanaal P. (een verbindingskanaal tusschen het Noordzee-kanaal en de Haarlemmer ringvaart). Terwijl de exemplaren van Engeland 4 à 6 mm. lang worden, bereiken de onze slechts een lengte van 2 mm. Het zijn primitieve Sabelliden (Fam. Amphicorinidae) met 5 onvertakte kieuwen aan weerszijde, waarvan alleen de middelste een bloedvat vertoonen. Zij bestaan uit 12 segmenten: 1 borstelloos kopsegment met een paar oogen, 8 thoracaal segmenten en 3 abdominaal segmenten. De haakvormige borstels van thoracaal en abdominaal segmenten verschillen...

The Parotoplana jondelii species-group (Platyhelminthes: Proseriata): a microturbellarian radiation in the Mediterranean
Provedor de dados: 16
Autores: Delogu, V.; Curini-Galletti, M.
Seven new Parotoplana species (Proseriata: Otoplanidae) from the Mediterranean, belonging to the P. jondelii complex, are described. They are characterized by the presence of numerous (14-22) copulatory spines. These are characteristically broad, and arranged in a girdle around the distal portion of the ejaculatory duct. In most species, dorsal and ventral spines are distinctly different from the rest of the spines of the girdle. This morphology of the copulatory spines is apomorphic for the genus Parotoplana, and supports a close relationship among these species. The new species (P. axi sp. n., P. crassispina sp. n., P. carthagoensis sp. n., P. gracilispina sp. n., P. ichnusae sp. n., P. obtusispina sp. n., P. pulchrispina sp. n.) are distinguished by...

New records of Marine Turbellaria from Norway
Provedor de dados: 16
Autores: Velde, G. van der.
INTRODUCTION During an excursion to Norway organized by the Department of Systematic Zoology of the Rijksuniversiteit of Leiden in August 1973, I had the opportunity to make some observations on Turbellarians of salt-marshes and rocky shores of the Trondheimsfjord (63o 37' N 9° 43' Ε) and the Stjörnfjord (63o 47' Ν 10° 7' Ε), a fjord connected with the Trondheimsfjord.  MATERIAL AND METHODS The greater triclad flatworms were mainly collected by turning stones on the salt-marshes and rocky shores. On the salt-marshes soil samples were taken. Each sample covered an area of 25 cm2 and was 3 cm thick. For obtaining the animals the soil samples were put in a jar filled with sea water. Lack of oxygen, due to decay of the vegetable matter, and the light of a lamp...

On a species of Lycastis and three aberrant forms of Nereidae from the Dutch East Indies
Provedor de dados: 16
Autores: Horst, R.
Lycastis meraukensis n. sp. Dr. J. W. R. Koch, member of the New-Guinea expedition of the Kon. Nederl. Aardrijkskundig Genootschap in 1904, found at Merauke in decayed wood of the Sago-palm 9 specimens of this worm, viz. 2 large ones, one of which is incomplete and 7 smaller ones. Unfortunately it is not mentioned whether the tree was met with in fresh or brackish water of the river or in salt water at the sea-shore. The dorsal side of some of the worms is dark flesh-coloured, whereas a red brown ring occurs around the anal segment. The largest specimen measures about 150 mm. in length and has a breadth of 7 mm. in the median body-region (without the parapodia); the number of its segments amounts to 170. One of the smaller specimens has a length of 60 mm....

On a gigantic Nereis (Ner. ijimai Iz.) from Japan
Provedor de dados: 16
Autores: Horst, R.
Among the Polychaeta of the Leyden Museum I met with a large Nereis-specimen, presumably collected in Japan, that in the structure of its parapodia so much agrees with Ner. ijimai1) described by Izuka from that country, that in my opinion it must be identified with this species, though there are some discrepancies in the armature of the proboscis. Nereis ijimai, like as Ner. oxypoda Marenz, Ner. virens Sars a. o. are characterized by the presence of a large, foliaceous dorsal ligula at the parapodia of the median body region and were ranged by Kinberg in his genus Alitta2). Unfortunately Izuka had only a single female specimen at his disposal, that was sexually mature and showed some epitocous transformation after the 40th parapodium by the presence of...

Malayan species of the genera Aphroditella, Hermione, Laetmonice and Aphrogenia
Provedor de dados: 16
Autores: Horst, R.
Genus APHRODITELLA Roule 1). Mc Intosh 2) in 1885 first described a minute Aphroditean-worm from the West-Indian abyss, the ventral bristles of which are „ densely pilose almost to the terminal hook and provided with a spur as in Laetmatonice" (Aphrod. intermedia); two years thereafter Ehlers 3) among the Annelids of the Blake, from a depth of 1719 M., met with an Aphrodite, that possesses ventral bristles, provided on one side with a beard of hairs (Aphrod. obtecta). Finally Roule among the Annelids of the Travailleur and the Talisman found an Aphrodite from a depth of 1084 M., that also possesses ventral setae with a pinnate appearance; with the two preceding species he ranges this form in a new genus Aphroditella. Several species of this genus appear to...

The Turbellaria of some Friesland lakes with incidental records of Gasteropoda and Hirudinea
Provedor de dados: 16
Autores: Young, J.O.
INTRODUCTION During the week 7th to 12th June, 1971 opportunity was taken of accompanying members of the I.B.P. team based at the Tjeukemeer, the Netherlands, on a boat journey through the Friesland lakes. The main aim of the author was to collect Turbellaria (Tricladida and Microturbellaria) from the vegetation and stones in the littoral zone of 16 lakes (see Table 1). However, any specimens of Gasteropoda and Hirudinea obtained in samples were also noted.  METHODS In the reed beds, mostly Phragmites (see Table 1), an F.B.A. net (60 meshes/inch = approx. 23.6 meshes/cm) mounted in a square frame on a 5 ft. (1.524 metres) pole was used to sweep through the vegetation and top layers of substratum for a given period of time (minimum 15 minutes). The contents...
