A key to the "X-Species" of North American fiddler crabs (genus uca) Naturalis
Hagen, H.-O. von.
Up to the late sixties of this century the number of species of the genus Uca occurring on the East and Gulf coasts of North America seemed rather well established. Usually ten species were listed: U. burgersi Holthuis ( = U. affinis (Streets)), U. leptodactyla Rathbun, U. minax (Le Conte), U. pugilator (Bosc), U. pugnax (Smith), U. rapax (Smith), U. speciosa (Ives), U. spinicarpa Rathbun, U. subcylindrica (Stimpson) and U. thayeri Rathbun. Subsequently, however, some uncertainty arose about the number of fiddler crab species of the Gulf coast area. Barnwell (1968) mentioned an undescribed species from Ocean Springs, Mississippi, and Salmon and co-workers described no less than three new Gulf coast species of Uca (Salmon & Atsaides, 1968; Novak &...

A Lantern Fish, Hygophum benoiti (Cocco, 1838), washed ashore in The Netherlands (Pisces, Myctophoidei, Myctophidae) Naturalis
Nijssen, H..
A small Lantern Fish, Hygophum benoiti (Cocco, 1838), was washed ashore at the beach of the village of Zandvoort in the Netherlands. This is the first record of a member of the family Myctophidae in the coastal waters of the Netherlands, and the northernmost record for the species. The occurrence of the species in the northern part of the North Atlantic is discussed, and the specimen is illustrated.

A large phylogeny of turtles (Testudines) using molecular data Naturalis
Guillon, J.-M.; Guéry, L.; Hulin, V.; Girondot, M..
Turtles (Testudines) form a monophyletic group with a highly distinctive body plan. The taxonomy and phylogeny of turtles are still under discussion, at least for some clades. Whereas in most previous studies, only a few species or genera were considered, we here use an extensive compilation of DNA sequences from nuclear and mitochondrial genes for more than two thirds of the total number of turtle species to infer a large phylogeny for this taxon. Our results enable us to discuss previous hypotheses on species phylogeny or taxonomy. We are thus able to discriminate between competing hypotheses and to suggest taxonomical modifications. Finally, we pinpoint the remaining ambiguities for this phylogeny and the species for which new sequences should be...

A Late Cretaceous gastropod homing scar (possibly ichnogenus Lacrimichnus) from southern Limburg, The Netherlands Naturalis
Jagt, J.W.M..
An isolated gastropod homing scar, etched into an arcoscalpelline (cirripede) scutum, is recorded from the upper Nekum Member (Maastricht Formation, upper Maastrichtian) at the ENCI-HeidelbergCement Group quarry. This trace may be assignable to the ichnogenus Lacrimichnus Santos, Mayoral & Muñiz, that comprises etching scars produced by Neogene calyptraeid and/or capulid gastropods and ostreid bivalves from southern Spain and Portugal. However, it differs from both ichnospecies currently contained in that ichnogenus, L. bonarensis and L. cacelensis, in showing a relatively deep depression around the rim, irregularly distributed pit- and slit-like depressions, and an irregularly subcircular outline. Despite the wealth of available hard substrates...

A Late Pliocene rodent fauna from Alozaina (Malaga, Spain) Naturalis
Aguilar, J.P.; Michaux, J.; Delannoy, J.J.; Guendon, J.L..
In this paper 11 species of rodents are described, that have been found in the fossiliferous karst fissure of Alozaina (Malaga, Spain). Three species of Stephanomys (Murinae) are present in this fauna: S. thaleri, S. minor, and the new species S. prietaensis. The latter exhibits a lesser degree of evolution than Stephanomys balcellsi from Valdeganga 7 and Islas Medas. The association of rodents from Alozaina is a new one for the Upper Pliocene in Spain. It indicates that the locality of Alozaina is younger than Moreda 1B and Rambla Seca Ab, and older than Valdeganga 7.

A late-glacial and holocene pollen diagram from Cienaga del Visitador (Dept. Boyaca, Colombia) Naturalis
Hammen, T. van der; Gonzalez, E..
In a C 14 dated pollen diagram from ”Cienaga del Visitador” (ca 6°8’N; 72°47’ W) in the Colombian Eastern Cordillera the zones Ib + Ic + II (including the Allerød and Bølling interstadials) form one fluctuation in the diagram, as the short cold zone Ic is not reflected. An earlier Late-glacial interstadial is recognized and is called Susacá-interstadial. It probably lasted from about 13900 to 13100 B.P., was colder than the Bølling-interstadial, and is probably reflected in pollen diagrams from other parts of the world. The Holocene part of the diagram shows very high Gramineae-percentages, apparently due to a considerable lowering of the ”tree-line”. This must have been caused by the fact that the Holocene local climate has been much drier than the...

A leaf anatomical contribution to the classification of the Linaceae complex Naturalis
Welzen, P.C. van; Baas, P..
The leaf anatomy of the Linaceae complex (Linaceae s.s., Hugoniaceae, Ixonanthaceae, Humiriaceae and Erythroxylaceae) and putative allies ( Ctenolophon, Lepidobotrys, Irvingiaceae) is surveyed, mostly on the basis of original observations (72 specimens, 27 genera), partly from data in the literature. Diversity in stomatal type, midrib and petiole vascularisation, sclerenchyma support, foliar sclereids, mucilage cells, secretory cavities, and cristarque cells provide evidence in favour of a separate family status of the members of the Linaceae complex. Allantospermum and Cyrillopsis are best accommodated in the Ixonanthaceae. Irvingiaceae (often treated in or near Simaroubaceae) show similarities with the Linaceae complex, albeit more closely to the...

A letter from the Editor Naturalis
Lam, H.J..
Fate has knocked at your door. It has reminded you that, as to the years of your life, you are no longer a young man, that your age will be sixty five on the day this little volume will be presented to you. Time and fate are inexorable powers. Sometimes the question has occurred to me, whether we have any right to speak of a “Jubilee”, whether one’s retirement from office or the attainment of high age is something to be gratulated upon, since these events are usually not exactly welcome to the person involved. Yet, I think there cannot be any doubt as to this. For, can there be ever more reason for deep satisfaction and gratitude than when a man may without self-reproach, look back upon an honest and successful life?

A Linnaeus NGTM interactive key to the Lithocolletinae of North-West Europe aimed at accelerating the accumulation of reliable biodiversity data (Lepidoptera, Gracillariidae) Naturalis
Doorenweerd, C.; Haren, M.M. van; Schermer, M.; Pieterse, S.; Nieukerken, E.J. van.
We present an interactive key that is available online through any web browser without the need to install any additional software, making it an easily accessible tool for the larger public. The key can be found at http://identify.naturalis.nl/lithocolletinae. The key includes all 86 North-West European Lithocolletinae, a subfamily of smaller moths (“micro-moths”) that is commonly not treated in field guides. The user can input data on several external morphological character systems in addition to distribution, host plant and even characteristics of the larval feeding traces to reach an identification. We expect that this will enable more people to contribute with reliable observation data on this group of moths and alleviate the work-load of taxonomic...

A list of species of Mammals from West-Sumatra and North-Celebes, with descriptionsof undescribed or rare species Naturalis
Jentink, F.A..
The Committee of the International Colonial Exhibition at Amsterdam has been kind enough to send to me a collection of Mammals made by Mr. F. von Feber during his residence in N. Celebes and W. Sumatra. The request was that I should subject the collection to a systematic review I feel sure that this review contains many facts interesting to zoologists, as it embraces certain very rare and partly unknown species and at the same time gives a very good idea of the peculiar Fauna of Celebes. The Mammals have been collected in the neighborhood of Loeboe Basong, Priaman, West-Sumatra, and in the vicinity of Amoerang, North-West-Celebes.

A list of the birds known from Roti and adjacent islets (Lesser Sunda Islands) Naturalis
Mees, G.F..
INTRODUCTION Father Verheijen (in press) has given a narrative of his visit to Roti, with a list of all birds recorded from material, personal observations, and hearsay. Although several of Verheijen's own field observations are entirely reliable, other species mentioned by him cannot be regarded as of anything but very doubtful occurrence. Therefore I have considered it useful to compile a list of those birds which are now known from collected specimens. Previous to Father Verheijen's studies, ornithological knowledge of Roti rested entirely on a visit to the island made by the anthropologist Dr. H. F. C. ten Kate in 1891 (22 August — 9 September). During his stay ten Kate did some collecting of miscellaneous zoological objects, which he forwarded to...

A list of the birds recorded from Bangka Island, Indonesia Naturalis
Mees, G.F..
An enumeration of bird specimens from Bangka present in museum-collections, has resulted in a faunal list of 172 species (176 forms). A discussion is given of the zoogeography of the island, the avifauna of which is mainly Sumatran in its affinities, but with a distinct Bornean influence. In contradistinction to a previously-published opinion (de Schauensee, 1958), there is no recognizable Javanese element in the avifauna.

A list of type specimens of fishes in the Zoological Museum, University of Amsterdam. 1. Order Mugiliformes Naturalis
Hoedeman, J.J..
In the earlier days the cataloguing and labeling of type specimens was rather careless, mostly with no mention that they were types. What we now term ’holotypes’ were previously referred to merely as ’types’, and both ’syntypes’ and ’paratypes’ were called ’cotypes’. Several of the original types were obscured in the files by writing them off as synonyms of other (earlier) species names, changing not only the generic, but even the specific names. Exchange of type material was extremely informal and often no record was made of the transfers. I have started to compile a catalogue of the type material in the museum in 1952, shortly after I was put in charge of the fish collections. Demands for loan of paratypes urged me, however, to complete the cataloguing...

A Lithothamnion bank at Bonaire (Netherlands Antilles) Naturalis
Zaneveld, J.S..
The part certain lime-secreting marine algae play in the building of coral reefs and in the formation of banks was discussed chiefly at the end of the last and in the beginnig of this century. At that time it was already known that extensive parts of the sublittoral zone of the Arctic sea were covered by a luxuriant growth of Lithothamnion species. Kjellman states in 1883 (p. 96) that along the northern coast of Norway Lithothamnion soriferum “covers large spaces of the bottom in great masses”, and that off the shores of Spitsbergen and Nova Zembla in 10 to 20 fathoms of water Lithothamnion glaciale “covers the bottom in deep layers for several miles, and altogether determines the general aspect of the vegetation wherever it occurs”, whereas Lithothamnion...

A Ludlow conodont fauna from Irian Jaya (Indonesia) Naturalis
Boogaard, M. van den.
The conodont fauna extracted from a boulder in the Lorentz River (southern Irian Jaya) is described. Arguments are put forward that the elements of Distomodus dubius (Rhodes, 1953) sensu Jeppsson, 1972 are part of the apparatus of species of Coryssognathus Link & Druce, 1972, a genus that ontogenetically acquires an apparatus of multidenticulate elements on account of the phenomenon that one coniform element of each of the several (curvature-transition ?) series successively incorporates its - to that time independently growing - coniform neighbours within its lamellae. Attention is called to the fact that probably also the apparatus of Distomodus kentuckyensis Branson & Branson, 1947 - as described by Cooper (1975) had a similar ontogeny and that...

A Middle Devonian atrypid brachiopod fauna from the Cantabrian Mountains, northwestern Spain, and its stratigraphic significance Naturalis
Struve, W.; Mohanti, M..
This paper records for the first time a rich atrypid brachiopod fauna from the Middle Devonian of the Cantabrian Mountains, Spain. A comparison of the Spanish atrypid fauna with that of Germany reveals a close similarity between the two. Even though the species are not identical, yet a comparison and stratigraphic evaluation has been made on the basis of external shape of the shells, ornamentation, etc. It is believed that the development of the Spanish species has been endemic or that the Spanish Middle Devonian sea was supplied with species immigrating from some place other than central Europe. On the basis of the distinct recession of Atrypa and the first appearance of the coarse ribbed species of Spinatrypa (Spinatrypa) a tentative Eifelian/Givetian...

A migratory flight of hover-flies (Diptera, Syrphidae) observed in Austria Naturalis
Jeekel, C.A.W.; Overbeek, H..
During an excursion sponsored by the Entomological Department of the Zoölogisch Museum, Amsterdam, to the village of Vent, Inner Oetztal, Tirol, Austria, the authors and the other participants, W. Dekkers, W. N. Ellis, Mrs. A. C. Ellis-Adam, W. van Raamsdonk, and H. J. L. T. Stammeshaus, witnessed the interesting phenomenon of a migratory flight of syrphid flies. The migration was first noticed around 9.20 a.m. on August 9th, 1967, when the senior author in the valley of the river Venter Ache near Vent saw a great number of insects flying at high speed into one direction. Under the impression at first that it concerned a nuptial flight of a large ant species, a specimen was caught in the air. When this turned out to be a hover-fly, it was at once realized...
