SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

Il existe encore une grande confusion au sujet du nom de genre correct s’appliquant à beaucoup de petits barbeaux de l’Inde orientale, lesquels, à juste titre, semble-t-il, ne devraient pas être maintenus dans le vieux genre Barbus. Pour ces espèces, et en particulier pour les espèces asiatiques, on a adopté le nom de genre Puntius HAMILTON, 1822. Cette façon de procéder pourrait être admise s’il n’y avait pas la question de légitimité du genre: les premiers auteurs à avoir adopté le nom de Puntius pour des barbeaux asiatiques ont été WEBER & DE BEAUFORT, 1916 (Fishes of the Indo-Australian Archipelago, 3 : 170—205). Mais ils n’ont pas approfondi le problème en ce sens que le genre est laissé sans un statut convenable, qui ne concorde pas avec les...

Notes on the Ichthyology of Surinam (Dutch Guiana), 4 Additional records of Siluriform Fishes (1)

Ano: 1958

URL: http://www.repository.naturalis.nl/record/504977

The present paper deals with part of a recently acquired collection of freshwater fishes, captured by Mr. J. VAN DER KAMP, Amsterdam, during his military service in Surinam in the years 1956 and 1957. All material is finely preserved and ecological data as well as numerous black and colour photographs by the collector add to the scientific interest of the collection.

Rivulid Fishes of the Antilles

Ano: 1957

URL: http://www.repository.naturalis.nl/record/504690

The present paper is chiefly based on the Rivulid fishes collected by Dr. P. Wagenaar Hummelinck in the Antilles during the years 1930, 1936, 1937, and 1955, and in addition on some specimens collected by various other investigators at earlier dates. Some of the specimens, in particular those belonging to Rivulus marmoratus have been recorded before by Wagenaar Hummelinck (1933, 1940), Sanders (1936), and de Beaufort (1940). With the aid of Hummelinck’s field notes and water analyses, some further information could be given on the habitat and salt tolerance of the island Rivulids, cf. table 3. I wish to express my sincere thanks to Dr. K. H. Voous, Curator of Birds of the Zoological Museum of Amsterdam, and Professor of Zoogeography at the Free University...

Een nieuwe kleine Gobiide vis met samengegroeide buikvinnen bij de man (Dormitator lophocephalus sp. nov.)

Ano: 1958

URL: http://www.repository.naturalis.nl/record/506224

Voorjaar 1949 ontving ik een kleine collectie levende vissen uit Suriname (Nederlands Guiana), door een zeeman verzameld in een poel nabij Paramaribo. Helaas is de juiste vindplaats niet nader aangegeven, dan enige kilometers ten zuiden van de hoofdstad. Onmiddellijk na ontvangst werden de vissen, die hier het onderwerp van bespreking zijn, in een groot gezelschapsaquarium (150 X 60 X 50 cm. hoog) ondergebracht, dat reeds werd bevolkt door verscheidene Nannostomini, Hasemania marginata, Rivulus cylindraceus, Acanthophthalmus kuhli, Dermogenus pusillus en Nannacara anomala en N. taenia.

Notes on the Fishes of the Cichlid Family I. Apistogramma cacatuoides sp. n

Ano: 1951

URL: http://www.repository.naturalis.nl/record/504706

The Dwarf-cichlid genus Apistogramma, very popular among aquarists and at present among students of animal behaviour, hitherto comprises about 16 forms, several of them hardly specifically distinguished, and probably only based on stages or sexes of other species. Nevertheless I found a new form among a small collection of fresh-water fishes, imported alive by a sailor from near Paramaribo, in Dutch Guiana. I had the opportunity to keep them in an aquarium for several months, and to study their behaviour. When at last they died I tried to identify this species, and it then appeared that they were new to science. They may, however, be identical with the species described by Innes as Apistogramma U2, of which I have been unable to find a scientific...

A new species of the genus Rivulus from Ecuador with additional records of Rivulus from the Upper Amazon and Ucayali rivers

Ano: 1951

URL: http://www.repository.naturalis.nl/record/505021

During August 1961 I received from Mr. E. Roloff (Karlsruhe, Germany), a well-known aquarist, three specimens of an unidentified Rivulus. The specimens were collected by Mr. Roloff during his journey to Ecuador early 1961. The sampling place is described by him in the followinig words: „Die Rivulus stammen aus einem kleinen, sehr schattigen Bach, der in die Lagune von Limoncocha mündet. Das Wasser ist sehr weich (etwa 1° DH) und hat eine Temperatur von etwa 26° Celcius, die sich natürlich zeitweilig noch erhöht. Der Bach ist nur etwa 1 Meter breit und hat einen geringen Wasserstand, oft nur 20 bis 25 cm. Die Rivulus halten sich hauptsächlich zwischen den Baumwürzeln und den hineingefallenen Zweigen auf. Büsche und Bäume überschatten diesen Bach sehr...

Studies on African Characid Fishes I. The tribe Alestidi (I)

Ano: 1962

URL: http://www.repository.naturalis.nl/record/505063

Among a recent importation from the Belgian Congo there was a multitude of lovely little aquariumfishes, mostly well-known to aquarists. but partly new to them, and some of these fishes even new to science. A large number of small ”Tetra’s” closely resembled the well-known species Petersius caudalis. Four perfectly preserved specimens (formol), were supplied to me by Mr. C. A. Spoelstra of Haarlem, a well-known aquarist-breeder. In order to identify this species, and designate its proper place, I started to study literature and material in the Museum. It then became evident that the classification and nomenclature of this group is far behind, a case somewhat similar to the one I recently discussed concerning the South-American Nannostomidi (Hoedeman, 1950...

Notes on the Ichthyology of Surinam (Dutch Guiana). The Catfish genera Hoplosternum and Callichthys, with key to the genera and groups of the family Callichthyidae

Ano: 1951

URL: http://www.repository.naturalis.nl/record/505046

This paper is based on the material of Callichthyid catfishes (genera Hoplosternum and Callichthys) present in the collections of the Zoological Museum, Amsterdam. The study was induced by some specimens of „kwi-kwi” introduced from Paramaribo by Mr. Arn. J. d’Ailly mayor of Amsterdam. Some of the specimens are still alive in the local aquarium. Two forms may clearly be distinguished and identified as Hoplosternum littorale (Hancock, 1828), and Hoplosternum thoracatum (Valenciennes, 1840), though both are subspecifically different.

Rivulid Fishes of Suriname and other Guyanas, with a prelininary Review of the Genus Rivulus

Ano: 1952

URL: http://www.repository.naturalis.nl/record/505101

The present paper embodies the results of a study of 362 specimens of the genus Rivulus from Suriname and the other Guyanas. So far, 58 species names (morphological species or subspecies) have been proposed, by a great many authors; these names are listed on pages 52—53. Of the 58, topotypical specimens have been examined in 8 instances. In order to facilitate a future review of the genus, which is in great need of revision, short remarks are made on the morphology and ecology of a number of specimens, from various localities, belonging to distinct species.

Notes on the Ichthyology of Surinam (Dutch Guiana) 3. A new species and two new subspecies of Nannostomidi from the Surinam river

Ano: 1959

URL: http://www.repository.naturalis.nl/record/506248

My previous account on the Nannostomidi (1951, The Amsterdam Naturalist, 1 (1): 11—27) dealt with the synonymy of the recognized species. Diagnoses were given of the three genera, Nannostomus, Poecilobrycon and Nannobrycon (new genus). The account was based on but little material, largely on descriptions in literature, yet it could readily be proved that the species described before belong to 5 species only and to 3 well defined genera. I have since had the opportunity to study rather large series from Surinam and some other localities. An entirely new species was found among this material, which is so interesting in many respects that it induced me to reconsider the matter of the phylogeny of the tribe.

Rediagnosis of the Old World Cyprinodont genus Aphanius

Ano: 1954

URL: http://www.repository.naturalis.nl/record/504931

Compared with their New World relatives of the subfamily Cyprinodontinae, the Old World Cyprinodonts are but little known. However, some interesting accounts on Turkish species, discovered by Kosswig, Sözer and Aksiray, have recently been published. Besides the species known, several new forms and species are described. While compiling an account on these fishes suitable for the home aquarium (Hoedeman & Bronner, 1950—1951), we felt some characters need reexamination, not only of Aphanius, but also of the North African genus Tellia which is said to differ from Aphanius only in the absence of ventral fins.

A list of type specimens of fishes in the Zoological Museum, University of Amsterdam. 1. Order Mugiliformes

Ano: 1951

URL: http://www.repository.naturalis.nl/record/504765

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...

Notes on the Ichthyology of Surinam (Dutch Guiana). 2. The Surinam representatives of Gasteropelecus and Carnegiella, with remarks on the tribe Gasteropelecidi

Ano: 1960

URL: http://www.repository.naturalis.nl/record/504883

This paper, the second note on the fishes of Surinam, is chiefly based on material recently acquisited by the Museum. The first paper dealt with the Callichthyidae (cf. Beaufortia No. 12). I am much indebted to Mr. C. A. SPOELSTRA of the „Blijdorp” Zoo-Aquarium in Rotterdam, who took care that the fine collection was preserved in the proper way, and who arranged preservation of specimens in the various localities. The members of the Blijdorp expedition had merely the task to bring back alive fishes for aquatic-dealers as well as the Blijdorp aquarium.
