| In preparing the volume of the Gobioidea in M. Weber and L. F. de Beaufort: The Fishes of the Indo-Australian Archipelago, several described species, collected in the Indo-Australian Archipelago or its surroundings, were not clear to me. Of a number of these the description was distinct enough to see what was meant with such a new species, but there were several species which I could not recognize from their description. Bleeker described a large number of new species, but, unfortunately, several of his descriptions are too vague to recognize the species. So many authors had described several species which proved, after comparison with Bleeker's type specimens or descriptions made after his types, to be either closely allied, or identical with species... |

| Material from three pieces of rock from Ramsåsa, site E, was divided into size fractions 0.106, 0.212, 0.355, 0.425 and 0.5 mm. Larger sizes were absent. The three assemblages were examined and compared with each other, also per fraction, and with residue samples from site E. The latter are proportionately not representative of the faunas of which they must have been part, specimens measuring 0.5 mm or more. The residue labels refer to Ørvig and his student Peyel. The results of the comparison between the assemblages from the rocks and from the residues are hardly complementary. Thelodont scales were obtained almost exclusively from the pieces of rock; acanthodian ‘modified trunk’ scales, spines and jawbones and rare birkeniid remains were restricted to... |

| The following pages contain a first report on the fishes collected by Dr. D. C. Geijskes and Mr. P. H. Creutzberg during the recent expedition to Dutch Guiana. A deplorable lack of time caused by the necessity to temporarily divert my attention from the present field of ichthyological research, compels me to publish these results before actually having finished the investigation of this rich and interesting collection. In consequence of this, the present paper concerns a part of the actual material only, and, though it includes in number the major part, a report on specimens belonging to some of the most interesting groups has to be postponed. For convenience' sake, the species recorded in the present paper have been arranged in the same order as used by... |

| In Dr. D. C. Geijskes' collection of Surinam fishes, mentioned in my previous paper on this subject (Boeseman, 1948), I found six specimens belonging to the so-called "sting rays" (Dasyatidae), representing three different species, and all very interesting in some respects.

| There are several descriptions of the anatomy of Orthragoriscus mola L., but no authors except Van Dobben (1935) have given a functional treatise concerning the mechanism of the jaw. Unfortunately the fish described by Van Dobben seems to have been abnormal. The description which follows is based on anatomical study of two sunfishes which stranded on the Dutch coast and were placed at our disposal by the Rijksmuseum van Natuurlijke Historie, Leiden. Specimen A, a female, stranded December 10, 1935 near Burgh, in the neighbourhood of Haamstede, on the Isle of Schouwen. It has been used for a cast in the Leiden Museum and was dissected by Dr N. Tinbergen and J. J. ter Pelkwijk December 13 and 14, 1935 at the Zoological Laboratory at Leiden. Specimen B, a... |

| In 1955, the late Dr. O. Schubart, Director of the Estaçao Esperimental de Biologia at Pirassununga (São Paulo, Brazil) kindly put at my disposal a small collection of fishes which he had assembled in the Mogi-Guassu (river) below the Cachoeira de Emas (Emas falls). Only a series of eight apparently conspecific specimens is discussed here. At first sight, the present specimens appear to closely resemble Pimelodella griffini Eigenmann, especially six examples with a prolonged first soft dorsal ray. However, excepting several minor differences, P. griffini has the dorsal spine prolonged instead of the first ray, while it has the adipose dorsal fin much shorter. Having only two specimens of P. griffini, moreover of dubious identity, available for comparison,... |

| Rejecting without valid argumentation a lectotype selection for Raja kenojei Müller & Henle, 1841, by the present author (1947), Ishiyama (1967) indicated another of the four Leiden types as such. Both selected specimens are shown to represent only the different sexes of the same species, which is not conspecific with R. kenojei sensu Ishiyama et al. (= ? R. japonica Nyström, 1887) but rather with R. porosa Günther, 1847, as understood by Ishiyama. One of the R. kenojei types is referred to R. meerdervoortii Bleeker, 1860, a distinct species not identical with R. kenojei in either interpretation, and of which R. macrophthalma Ishiyama, 1950, may well prove to be a junior synonym. Müller & Henle's coloured illustration of R. kenojei, made after a... |

| Through the courtesy of Dr. J. Roux, to whom I am very thankful, I received for identification from the "Naturhistorisches Museum" at Basle a collection of Fishes from Siam, collected by Dr. H. Bernatzik in 1936 and 1937. The collection consists of representatives of 37 species, among which the type of a new species. Barilius bernatziki nov. spec. (fig. 1). D. 3.8; A. 3.9; P. 1.14; V. 1.8; L.l. 31 + 2; L.tr. T. 6 1/2 / 1/ 3 1/2. Body elongate, strongly compressed, dorsal profile less convex than ventral profile; height 3 1/4 in length, 4 1/5 in total length. Head compressed, 4 in length, a little more than 5 in total length. Eye 3 1/2 in head, interorbital flat, 1 eye diameter. Circumorbital bones large. Snout as long as eye, tip before upper edge of... |

| INTRODUCTION Difficulties with the identification of some West-Indian Belonidae and an investigation into the merits of the generic name Strongylura as against Tylosurus led to a revision of the Belonidae, the result of which is published here. As will be seen on the following pages, this revision is by no means final; many problems remain to be solved, much synonymy given here is doubtful, lack of material prevented me from investigating the possible presence of slight geographic variation in the widely distributed species; some apparently valid species are left out altogether (I listed their names on p. 5) because no material has been available, and other names remain doubtful as it has not been possible to examine the type specimens. There is also the... |

| Pieter Bleeker described 72 new species and 10 new genera of elopoid and clupeoid fishes from the Indo-Malayan Archipelago. From amongst the Bleeker material in the Rijksmuseum van Natuurlijke Historie in Leiden and the British Museum (Natural History) in London, it has been possible to find the holotypes or designate lectotypes or putative neotypes for almost all these species. The types are fully described, with notes on synonymies and affinities. Of the species listed, 24 are considered senior synonyms, and 5 Bleeker genera are accepted. |

| Thacker (2004b) regarded the gobiid fish Gnatholepis cauerensis (Bleeker) as a synonym of Gnatholepis anjerensis (Bleeker) and treated G. scapulostigma Herre as the replacement name for what other recent authors had identified as G. cauerensis. The holotype of Gobius cauerensis Bleeker from the Nationaal Natuurhistorische Museum in Leiden is redescribed. Because its colour pattern has faded, the original Bleeker painting is reproduced, the diagnostic colour features noted, and comparison provided with an underwater photograph taken of a specimen before it was collected in the Mentawai Islands (near the type locality of Kauer, Sumatra). Gnatholepis cauerensis is a valid species distinct from G. anjerensis. G. scapulostigma Herre is returned to the synonymy... |

| From Mr. A. Werner, collector and animal dealer at Munich, Germany, the Leiden Museum received a collection of 1012 well preserved specimens of fishes from Stanley Pool (Léopoldville), Belgian Congo. As several species proved to be new for this locality and are not mentioned in Poll's paper on the fishes from Stanley Pool (1939), the following publication was considered worth while. Moreover, a new Synodontid species, Synodontis werneri, is described. In the present report, the various species are recorded in the same order as in Poll's account. The name of the locality, being always the same, is omitted further on. Protopterus dolloi Boulenger 2 ex., January 1956, 76-91 mm. Both specimens are juvenile and have the tail slightly mutilated. Scales in 90-98... |

| Since the publication of a paper on Auchenipteridae and Pimelodidae (Mees, 1974), I have received additional material of several of the genera there revised. This material includes a new species of Pseudopimelodus from Venezuela, increasing the number of species of that genus to six (two of which have several subspecies), and a new species of Microglanis from Ecuador, the eighth member of its genus. The main purpose of this paper is the description of these two new species. In addition, fresh material of Microglanis iheringi, a species of which previously I had examined only a single specimen, enabled me to supply some additional notes on it as well as an illustration showing its distinctive characters much better than do the photographs published by Gomes... |

| In his valuable report on the freshwater fishes of British Guiana, Eigenmann (1912, pp. 64-73) gave a list of the species, together with comparable lists on the freshwater fishes of the adjacent regions. In sharp contrast with the number of 266 species reported from the Essequibo area only, the total amount of Surinam species proved to be but 118! Although since Eigenmann compiled these lists some more species have been reported from Surinam, the general situation has remained essentially the same, clearly showing the backward state of ichthyological research in this area. A possibility to improve our knowledge of this subject came when during the last four years the Rijksmuseum van Natuurlijke Historie received several more or less extensive collections... |

| Hypopygus lepturus Hoedeman, 1062, was hitherto known from the holotype and one paratype only, both imported aquarium specimens. In this paper the type locality of the species is restricted. Additional distributional data from Surinam are given, together with records on the occurrence of H. lepturus in Guyana, Venezuela, Colombia, Brazil, and on the very likely occurrence in Peru. Comparative notes on Steatogenys elegans (Steindachner, 1880) sensu Boulenger, 1898, are added because of the similar appearance of both species. The synonymy of Tateichthys duidae La Monte, 1929, with Steatogenys elegans is established. |

| A visit to the Leiden Museum by Professor Dr. L. F. de Beaufort, assembling data for his next volume on the Fishes of the Indo-Australian Archipelago, prompted me to investigate the nomenclatorial difficulties still existing around the Plectognath genus Triodon and its single known species. One of the principal items consulted, Herre's 1953 Check List of Philippine Fishes, itself not without serious flaws and therefore illustrative for the present problem, proved a very satisfactory starting-point, especially as it contains the only recent and rather extensive compilation of previous literature on the subject. Still, Herre's enumeration of references is not at all exhaustive, and numerous additions taken both from systematic literature and from general... |
