Última About the malacological subdivision of Curaçao; a review Naturalis Wagenaar Hummelinck, P.. Burrington Baker (1924) states that Curaçao can be divided into three distinct faunal areas. Stock (1977) mentions the occurrence of three subspecies of hadziid amphipods almost exclusively confined to different parts of Curaçao. The results of a study of the distribution on this island of various subspecies of the gastropods Cerion uva, Brachypodella raveni, Tudora megacheilos and T. rupis, however, do not support the hypothesis of a tripartite Curaçao.

Ano: 1990 URL: http://www.repository.naturalis.nl/record/504426 Additional notes on Caribbean tiger-beetles of the genera Cicindela and Megacephala Naturalis Wagenaar Hummelinck, P.. The author is indebted to Mrs. C. S. OLDENBURGER – EBBERS, Mrs. J. S. DE LEEUW VAN WEENEN – DE HART and Mr. F. VAN DER HEIDE for allowing him to include a number of measurements and other data, produced during their student’s practical course in taxonomy at the Zoological Laboratory of the Utrecht University in 1967-1969. CARLA OLDENBURGER (cf. Table 2, Figs. 27-34) and JEANNETTE DE LEEUW VAN WEENEN (cf. Figs. 39-41) studied the greater part of the Cicindela material, while VAN DER HEIDE (cf. Table 5, Figs. 42-46) examined most of the Megacephala specimens. Loans from the Science Museum of the Institute of Jamaica and from the British Museum (Natural History) are gratefully acknowledged. Several interesting specimens collected by Dr. Ir. R. H. COBBEN...

This paper presents a survey of the present situation of Cerion in the Cayman Islands, with reference to the problems revealed by CH. J. MAYNARD’S “Monograph of the genus Strophia”, 1889. This may be of interest to taxonomists who would like to investigate in a “modern way” a species complex in which any “biological species concept” appears to fail. The study is based on material collected in Grand Cayman, Little Cayman and Cayman Brac, from May 16 until June 12, 1973. CLENCH (1964) considers the names of all 14 species described by MAYNARD from Little Cayman and Cayman Brac to be synonyms of Cerion pannosum (Maynard), with the exception of Strophia nana which he accepts as Cerion nanus (Maynard). While agreeing with CLENCH as regards the status of... Tipo: Article / Letter to the editor Ano: 1980 URL: http://www.repository.naturalis.nl/record/506181 Caribbean Scyphomedusae of the genus Cassiopea Naturalis Wagenaar Hummelinck, P.. When the author beheld the tranquility and the magnitude of a Caribbean mangrove-lagoon for the very first time, he was so much impressed by the wealth and the complexity of this habitat that he could not but devote his special attention to a number of simple Cassiopeas, lazily pulsating amidst the turtle-grass. Moreover these Bonairean animals challenged him to further research, because at first view, their appearance showed some striking differences from a description given some years before by STIASNY, with reference to Cassiopeas collected by VAN DER HORST on Curaçao. The result was a lengthy paper “Zur Kenntnis der Scyphomedusen-Gattung Cassiopea” (1933). The present article may be considered as a continuation, except for one thing; several subjects... Tipo: Article / Letter to the editor Ano: 1968 URL: http://www.repository.naturalis.nl/record/506244 Caribbean tiger beetles of the genus Megacephala Naturalis Wagenaar Hummelinck, P.. The small collection of tiger-beetles, belonging to the genus Megacephala, which is the subject of this paper, was incidentally made by the author during his visits to the Lesser Antilles in 1936-’37 and 1948-’49. The greater part of the material has been deposited at the “Zoologisch Museum” of Amsterdam and the “Rijksmuseum van Natuurlijke Historie” at Leiden. Some specimens (27 M. sobrina from Porlamar, Margarita, and Deenterra, Bonaire) were presented to the collections of the American Museum of Natural History, British Museum, Deutsches Entomologisches Institut, incl. Coll. Horn, Hope Department of Entomology at Oxford, The Imperial College of Tropical Agriculture in Trinidad, Institut Royal des Sciences Naturelles de Belgique at Brussel, United States... Tipo: Article / Letter to the editor Ano: 1955 URL: http://www.repository.naturalis.nl/record/506134 Description of new localities Naturalis Wagenaar Hummelinck, P.. A recent collecting trip extended the region to which these Studies originally referred in such a way that it seemed wise to change the original title, so that not only the arid area off the North coast of South America was indicated as the field of study. Although as yet these Studies are principally based on material collected by the editor on his three trips to the Caribbean, this volume proves that results obtained from material of different origin will be incorporated. Tipo: Article / Letter to the editor Ano: 1953 URL: http://www.repository.naturalis.nl/record/506240 Description of the Localities Naturalis Wagenaar Hummelinck, P.. A few localities in which collecting has been done in 1930 (cf. Zool. Jb. Syst. 64, 1933) are included without special numbering. A capital-letter after the station-number indicates a different habitat or a comparable habitat in another locality; an ordinary-letter indicates that the same habitat has already been studied before. Tipo: Article / Letter to the editor Ano: 1940 URL: http://www.repository.naturalis.nl/record/506241 Land and fresh-water localities Naturalis Wagenaar Hummelinck, P.. Many years have passed since short descriptions were published of the land and fresh & brackish-water habitats sampled in the Caribbean during the author’s three zoological collecting trips in 1930, 1936/37, and 1948/49 (these Studies, vols. 1 and 2, 1940, and vol. 4, 1953). Sampling was continued in 1955, 1963/64, 1967, 1968, 1970 and 1973. Data on the marine and saltpond habitats from which material was gathered were published in Studies 51, 1977. Collecting was done single-handed and often rather incidentally, as a rule with no other equipment than a knife, forceps, a beetle-sieve and a fine-meshed dip-net, the author confining himself to those places which presumably would yield a more or less representative sample within a short time. Yet, the... Tipo: Article / Letter to the editor Ano: 1981 URL: http://www.repository.naturalis.nl/record/506167 Mammals of the Genera Odocoileus and Sylvilagus Naturalis Wagenaar Hummelinck, P.. Whilst visiting the Leeward Group, little time could be spared to the collecting of mammals; from Odocoileus and Sylvilagus however, a rather representative series could be obtained. Regarding this, I must offer my grateful thanks and appreciation to the people who so ably and kindly assisted in securing the specimens. I am especially obliged to Mr. van der Linde Schotborgh for presenting me with a living Curaçoan deer and to Mr. de Wit for organizing our three shooting-parties, ending with the aquisition of the type of Odocoileus gymnotis curassavicus. Señorita Fanny Maneyro made me a present of a two days old fawn, on the occasion of a short visit to her uncles estate on the Peninsula de Araya. Little “Chacopato” was bottle-fed in my room in Porlamar,... Tipo: Article / Letter to the editor Ano: 1940 URL: http://www.repository.naturalis.nl/record/506190 Marine localities Naturalis Wagenaar Hummelinck, P.. Some twenty-five years have passed since short descriptions were published of marine and saltpond habitats sampled in the Caribbean during three zoological collecting trips made by the author in 1930, 1936/37 and 1948/49 (these Studies, vol. 4, no. 17, 1953). Sampling of the shallow coastal waters of the Caribbean was continued in 1955, 1963/64, 1967, 1968, 1970 and 1973, during six visits the main purpose of which was not always the study of the marine fauna. Although collecting was done single-handed and rather incidentally, with no other equipment than a knife, fine-meshed nets, formaldehyde and alcohol, the material collected proved to be sufficiently valuable for scientific purposes to justify the publication of a list of the new marine localities. In... Tipo: Article / Letter to the editor Ano: 1977 URL: http://www.repository.naturalis.nl/record/506104 Mollusks of the Genera Cerion and Tudora Naturalis Wagenaar Hummelinck, P.. Although the islands of Curaçao, Aruba and Bonaire have received the attention of many naturalists, from the beginning of the West-Indian trade until to-day, it was not before 1924 that a suitable publication on the “Land and Freshwater Molluscs of the Dutch Leeward Islands” was written by Horace Burrington Baker. I should like to express my appreciation of this work, which not only facilitated my studies, but, at the same time, forced me to collect the landshells of these islands in a most intensive and systematical way, — because I should not have been competent to critisize his results, if I had not had a material of at least the same value at my disposal. As Baker very precisely localized his stations, I could collect a large series of topotypes of...

This publication deals with some agaves which were collected by me participating as biologist in a geological excursion under Prof. Dr. L. M. R. Rutten and Mrs. Dr. C. J. Rutten-Pekelharing, in the beginning of 1930, to the West Indies. From 14 April to 4 May we camped in the western part of Curaçao, from 10 May to 10 June Bonaire was visited and from 16 June to 9 July we passed through Aruba. In preference to the collection of a large number of different forms of Agave, an intensive investigation of the forms found on a few localities was made. I hoped thereby to acquire some information about the variability, and insight into the problem of the concept of species, not to be obtained by the study of herbarium material. — Other material was collected... Tipo: Article / Letter to the editor Ano: 1936 URL: http://www.repository.naturalis.nl/record/535138 Notes on Agave in the Netherlands West Indies and North Venezuela Naturalis Wagenaar Hummelinck, P.. In Curaçao, Aruba and Bonaire the most common species of Agave is A. vivipara. Although the variability is rather great, this species is nearly always easily recognizable. In Aruba, however, in two localities agaves are found, namely A. Rutteniae and A. arubensis, which differ from A. vivipara in their generative parts only. The A. Cocui, which occasionally occurs in Curaçao and Bonaire, but which has probably been introduced from the coast of Venezuela, differs from these species, both in shape and size. A. Boldinghiana, which is found here and there on alle three islands, is in herbarium material not always easily distinguished from the above named species, in the field it is always easily recognizable. A. Karatto, which is frequently cultivated as a...

La flora de cactos de las islas situadas entre Trinidad y la península de La Goajira comprende trece especies silvestres, aparte del género Melocactus: Pereskia Guamacho, Opuntia caribaea, O. curassavica, O. Wentiana, O. elatior, Rhipsalis cassutha, Hylocereus Lemairei, Acanthocereus pentagonus, Lemaireocereus griseus, Cephalocereus lanuginosus, Cereus repandus, C. margaritensis, C. margaritensis var. micracanthus y Mammillaria simplex. Doce especies son aborígenes de las islas venezolanas y ocho de las islas neerlandesas. Con exclusión de Tortuga, las islas venezolanas no poseen especies que no se encuentren en el continente. Margarita, con las islas situadas más hacia el star, Los Frailes, Los Testigos y Blanquilla, poseen cinco especies: Pereskia...

The interest of the second author in the variability of Melongena melongena (L.) was aroused by the discovery of a population of dwarf specimens living in shallow tidal pools connected with the mangrove lagoon of Lac, Bonaire, in 1976 (see Figs 1-4). Further collecting resulted in bringing together a rather large number of recent and subrecent shells from various Caribbean localities which served as a base for the present study (see Appendix). Tipo: Article / Letter to the editor Ano: 1986 URL: http://www.repository.naturalis.nl/record/506056 Pseudoscorpions of the genera Garypus, Pseudochthonius, Tyrannochthonius and Pachychitra Naturalis Wagenaar Hummelinck, P.. Whilst visiting the Leeward Group, in 1936—1937, I couldn’t help being fascinated by the striking occurrence of representatives of the arachnid order Chelonethida on every island of this arid region which invited me to an investigation of its soil fauna. This first publication of a serial on a group in which so much taxonomical work has still to be done, may be considered as the inevitable aftereffect of these first-sight impressions. My grateful thanks to JOSEPH C. CHAMBERLIN (Forest Grove, Oregon) and C. CLAYTON HOFF (Fort Collins, Colorado) for their interest in my work and to WILLIS J. GERTSCH and E. BROWNING for letting me have the loa.n of some material deposited in The American Museum of Natural History and the British Museum (Natural History). Tipo: Article / Letter to the editor Ano: 1948 URL: http://www.repository.naturalis.nl/record/506097 Scorpions Naturalis Wagenaar Hummelinck, P.. This survey of the scorpions of the Leeward Group is based on author’s collection and therefore includes some mainlandrecords from northern Venezuela and northeastern Colombia. Material from Curaçao, deposited in the “Zoölogisch Museum, Amsterdam” (A) and the “Rijksmuseum van Natuurlijke Historie, Leiden” (L) has been included, and the few island-records which were found in literature mentioned. Important new localities are indicated by an exclamation-mark. A description of the localities may be found in the 1st and the 4th paper of this series.
