A contribution to the knowledge of the pectinacean Mollusca (Bivalvia: Propeamussiidae, Entoliidae, Pectinidae) from the Indonesian Archipelago Naturalis
Dijkstra, H.H..
During the Indonesian-Dutch SNELLIUS -II Expedition (1984-1985) to the Indonesian Archipelago 46 pectinacean species were collected from the Flores Sea and Banda Sea (5°52'-9°57'S, 118°12'-123°58'E) at littoral to bathyal depth (835 m). One new pectinid genus, viz. Glorichlamys gen. nov., six new propeamussiids, viz. Parvamussium araneum spec. nov., Parvamussium carbaseum spec. nov., Parvamussium cassium spec. nov., Parvamussium undosum spec. nov., Parvamussium virgatum spec. nov., Cyclopecten cancellus spec. nov., and one new entoliid, viz. Pectinella aequoris spec. nov. are described. Twelve new records of Pectinacea for this region are mentioned. For Ostrea squamosa Gmelin, 1791 a lectotype is designated. In addition Pectinidae of the...

A contribution to the phytogeography of the Angmagssalik area, East Greenland, with special reference to Chionophily Naturalis
Molenaar, J.G. de.
As delimited by Polunin (1951), the Arctic is situated on the Northern hemisphere North of (1) a line 50 miles North of the coniferous forest line, (2) the Northern limit of microphanerophytic growth, or (3) the Nordenskjöld line, according to the formula V = 9-0,1K. According to this delimination the whole of Greenland belongs to the arctic region. Within the Arctic a subdivision in low- and high-arctic regions is usually recognized. Larsen (1960) marks this transition on the East coast of Greenland near Cape Dalton. Low-arctic East Greenland thus stretches from 60° to 69°30' N. lat. The Angmagssalik area in Southeast Greenland ranges from circa 65° to 67°20' N. lat. Between the Sermilik and the Kangerdlugssuatsiak fjords to the West and East, Denmark...

A contribution to the wood anatomy of South American (Chiefly Suriname) Rubiaceae. I Naturalis
Koek-Noorman, J..
A general description of the structure of the wood of the Rubiaceae is given, based on examination of samples from most subfamilies. The results of the author’s investigation are compared with the data in the literature. The features of vessels, rays, and parenchyma agree well with those reported by other investigators. When the fibres are divided into libriform fibres and fibre tracheids in the sense of Janssonius, the correlation between the distribution of these organs and recent taxonomic subdivisions of the family is better than when all fibres with bordered pits are regarded as fibre tracheids.

A contribution to the wood anatomy of South American (Chiefly Suriname) Rubiaceae. II Naturalis
Koek-Noorman, J..
This paper contains a discussion of the taxonomic subdivisions of the Rubiaceae as proposed by Schumann, Verdcourt, and Bremekamp. Generally speaking, the subdivisions as proposed and delimited by Bremekamp agree best with the characters of the wood structure, as observed by the author. Furthermore a key to the Suriname genera is given.

A contribution to the wood anatomy of the Cinchoneae, Coptosapelteae and Naucleeae (Rubiaceae) Naturalis
Koek-Noorman, Jifke.
Wood samples of a number of Cinchoneae and Naucleeae sensu Schumann were studied, and the results compared with data found in the literature. On the whole the representatives of the Cinchoneae appeared to show a rather high degree of similarity among each other with the exception, however, of the genera Coutarea, Exostemma, Corynanthe, Crossopteryx, and Hymenodictyon. The creation of the tribe Coptosapelteae and its inclusion in the Ixoroideae seem to be corroborated by the particular character of the wood anatomy. The restriction of the Naucleeae to Nauclea L. ( Sarcocephalus Afzel.) is not supported by the anatomy of the wood.

A contribution towards our knowledge of the Polychaeta of South Africa Naturalis
Horst, R..
2. Nereidae 1). Nereis (Platynereis) striata (Schm.). (Mastigonereis striata Schm.). 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. The specimens of Schmarda and of Willey were somewhat larger, measuring 50 mm. in length, with about 80 segments. Nereis striata is characterized by a conspicuous coloration,...

A contribution towards our knowlegde of the Polychaeta of South Africa Naturalis
Horst, R..
1. Amphinomidae and Aphroditidae. Professor Max Weber, during a short stay in South Africa in 1894, made a small collection of Annelids, which he kindly handed me over for examination. As I found among them some species, which for the first time are mentioned from this interesting region, where the fauna'sof the Atlantic and the Indo-Pacific meet each other, it will not be without interest to publish a short note about them. Euphrosyne capensis Kinb. 1). (— polybranchia Schm.) 2).

A coral-eating barnacle, revisited (Cirripedia, Pyrgomatidae) Naturalis
Ross, Arnold; Newman, William A..
The coral-eating barnacle Hoekia monticulariae (Gray, 1831), the only internal parasite among the Thoracica described to this day, is characterized by an irregularly-shaped shell nestled cryptically between the polyps of the hermatypic coral Hydnophora Fischer, 1807, which occurs throughout most of the Indo-West Pacific. Because of its protean form, cirripedologists have failed to appreciate the diversity of taxa related to Hoekia, , a presumed monotypic genus. We describe seven new species divided between Hoekia and three new genera, Eohoekia, Parahoekia, and Ahoekia for which the Tribe Hoekiini is proposed. As in other pyrgomatids, calcareous overgrowth by the coral is inhibited around the edge of the wall and aperture. But in Hoekiini a pseudopolyp,...

A correction Naturalis
Maas Geesteranus, R.A..
In Persoonia 2: 389. 1962, the new combination Hydnellum piperatum (Coker) Maas G. was proposed, but it escaped my attention that the basionym, Sarcodon piperatus, had not been provided with a Latin description, rendering the new combination invalid. The following diagnosis, taken from Coker’s description and augmented with a few notes of my own, should validate the name.

A craniometric comparison of Holocene populations of Myotis mystacinus (Kuhl, 1817) and M. brandtii (Eversmann, 1845) (Chiroptera, Mammalia) Naturalis
Rybář, P..
This paper presents the results of an analysis of about four hundred skulls of Myotis mystacinus and M. brandtii of the Holocene age from the Záskočie Cave (Central Slovakia). A review of criteria for species determination is presented, including a new criterion concerning the morphology of P4 roots, as well as the results of a statistical survey of skull dimensions and correlation and regression analyses. The author concludes that the above mentioned bats are not sibling species, but that they belong to different subgenera of the genus Myotis.

A crinoid crown from the Wenlock (Silurian) of Coalbrookdale, Shropshire, England Naturalis
Donovan, S.K.; Lewis, D.N..
The specific diversity of fossil crinoids from the Much Wenlock Limestone Formation at Dudley, Worcestershire, and in Shropshire differ by an order of magnitude. The latter are relatively depauperate and include only about six nominal species. Over 165 years ago, a specimen from Coalbrookdale, Shropshire, was identified as Cyathocrinites tuberculatus Miller (= the taxocrinid flexible Protaxocrinus tuberculatus (Miller)). This specimen, although indifferently preserved, is distinct from other Silurian crinoids of the British Isles and is described herein as a monobathrid camerate, Macrostylocrinus? jefferiesi sp. nov. This species has a moderately large, conical dorsal cup with at least 20 arms, broad primibrachials, a granular surface sculpture and no ray...

A Critical Revision of the Genus Aristida being a preliminary study and an introduction to the monograph Naturalis
Henrard, J.Th..
A species with the habit of Aristida divaricata H. et B., but welldistinguished by the wanting column and the curious tuberculate lemmas. Closely allied to Aristida gentilis HENR., which differs however in the other position of the glumes and in the smooth lemma. The species resembles in some characters the Aristida Parishii HITCHC., the latter has however a totally different shape of the panicle and the lemma is not tuberculate-hispid, but scabrous only on the upper half. Among duplicates from the U. S. Nat. Herbarium, kindly received from Mrs. A. CHASE, I found a second plant belonging to the species, a plant also collected in Arizona, north slope of Santa Rita Mountains, leg. D. GRIFFITHS no. 7269.

A Critical Revision of the Genus Aristida being a preliminary study and an introduction to the monograph Naturalis
Henrard, J.Th..
Being engaged during several years with a revision of the grasses preserved in the Rijks-Herbarium at the University of Leyden, my attention was called to the group of the Stipeae, and especially to the very difficult genus of Aristida. After an exhaustive study of the literature, I thought it desirable to have a monograph of this genus, containing extensive keys for the determination of all the species hitherto known, and I resolved to prepare such a work. It has been my good fortune that I had at my disposal not only the valuable collections of the Rijks-Herbarium, but that by the courtesy of the directors of the great herbaria in Europe and in America, I could study many thousands of specimens, among them authentic specimens and types. So several years...

A Cytotaxonomic study of Viola in the Netherlands Naturalis
Gadella, T.W.J..
1. The chromosome numbers of 10 species of the genus Viola in the Netherlands were determined. 2. Viola riviniana has various chromosome numbers: 2n = 35, 40, 45, 46, 47 (most often 2n = 40). 3. It was not possible to find a correlation between the external morphology and the various chromosome numbers in V. riviniana. 4. Despite the variability of V. riviniana it proved impossible to divide the Dutch material into subspecies. 5. Some differential characters of V. riviniana and V. reichenbachiana are described. 6. V. canina is not variable in cytological respect in the Netherlands. 7. V. calaminaria is not related to V. lutea but to the V. tricolor complex.
