| Stock, J.H. & A.G. Humes. Copepoda associated with Echinoidea from the West Indies. Studies nat. Hist. Caribbean Region 72, Amsterdam, 1995: 25-46. Four species of Copepoda (three Siphonostomatoida, one Poecilostomatoida) are recorded as associates of shallow-water echinoids, from Curaçao, St. Martin, Jamaica, Puerto Rico, and the Bahamas. The siphonostomatoids Chelacheres longipalpus and C. optans belong to a new genus and species of the family Asterocheridae. Another species of the same family is provisionally attributed to Asterocheres simulans (T. Scott, 1898), previously recorded from Europe only. A fourth species, of the genus Pseudanthessius (family Pseudanthessiidae), belongs to a new species, Ps. exilicornis. |

| Eleven species of Pycnogonida are recorded from depths between 230 and 3663 metres in the northern Atlantic. Of these, Nymphon inerme Fage, 1956, hitherto known from a single female specimen collected in the Kermadec Trench in the Pacific, is redescribed, whereas Ascorhynchus pudicum Stock, 1970 is recorded for the second time from a station near the type locality. |

| Three species of Amphipoda are recorded from interstices of a marine beach on the island of Santiago, Cape Verde Archipelago: Cabogidiella littoralis n. gen., n. sp. (Bogidiellidae), Psammogammarus spinosus n. sp. (Melitidae), and Idunella sketi Karaman, 1980 (Liljeborgiidae). The latter, widely distributed species (West Indies, Canary Islands), is new to the Cape Verde Islands. Furthermore, an isopod is described from the same locality, Caecostenetroides mixtum n. sp. (Gnathostenetroididae). |

| In a series of NATO subsidized publications, under contract RG 001/88, scientists from various NATO countries (D, F, NL, SP, UK, and USA) have executed comparative studies on the aquatic biotas, in particular the stygofauna, of various mid-Atlantic islands: Madeira, Canary Islands, Cape Verde Islands, and Ascension. We were fortunate enough to receive NATO support again (under reference CRG 940976) for a follow-up study on another island in the central Atlantic, St. Helena. |

| Hadziid Amphipoda are known from inland groundwaters of 14 West Indian islands, Thermosbaenacea from those of 9 islands. Only 4 islands show joint occurrence of both groups. Even in islands of joint occurrence, hadziids occur significantly more often alone in a given locality, than in combination with Thermosbaenacea or Copepoda Cyclopidae. The latter two groups do not show any significant avoidance of each other. Some possible causes for the non-random occurrence of small groundwater Crustacea are discussed; it seems most likely that hadziids predate on other Crustacea, such as Thermosbaenacea or Cyclopidae. This predation may have, or have had, influence on the actual distribution patterns of the groups under consideration. |

Entomolepididae were never recorded before from the Antilles. Two species have been discovered: Parmulodes verrucosus Wilson, 1944 and Parmulella emarginata n. gen., n. sp. Both are associates of the sponge, Chondrilla nucula, the former in Puerto Rico, Curaçao and Aruba, the latter in Curaçao. |

| In the present series of papers the results of two different field trips to the West Indies are coordinated. Each paper, dealing with a convenient taxonomic group, will be numbered separately. The sequence of the taxonomic units is arbitrary. Part of the material on which the results are based was collected by J.H.S. during a five months’ stay (October 1958-February 1959) in the Dutch West Indies (or Netherlands Antilles, as they are more officially called), which was made possible by a grant from the Netherlands Foundation for the Advancement of Research in Surinam and the Netherlands Antilles (WOSUNA), Amsterdam. The greater part of the time was spent at the Caribbean Marine Biological Institute, Piscadera Bay, Curaçao, although short visits to the other... |

| A number of Copepoda of the family Lichomolgidae, all endoparasitic in tropical holothurians, has been described. All belong to the group of genera related to Paranthessius, as borne out by the structure of their appendages, although the body-shape often has undergone modifications due to the endoparasitic mode of life. A key to the genera of the Paranthessius group is provided. Descriptions and illustrations are given of Scambicornus carinatus n.sp. (host Stichopus monotuberculatus from the Ethiopian Red Sea coast), Lichothuria mandibularis n.gen., n.sp. (host Halodeima atra from the Gulf of Aqaba), Diogenella spinicauda n. gen., n. sp. (host Holothuria mexicana from Curaçao), D. seticauda n.sp. (hosts Halodeima surinamensis and Holothuria impatiens from... |

| Quite a few endoparasitic copepods are known from Indo-Pacific stony corals, but not a single species has so far been recorded from the West Indies. Intensive search in the past few decades has even supported the prevailing opinion that West Indian stony corals are devoid of endoparasitic copepods, and that this absence could be related to the complicated zoogeographic past of the West Indian reef. However, during a 6-months stay (November 1973—April 1974) at the Caribbean Marine Biological Institute, in Curaçao (Netherlands’ Antilles), endoparasitic copepods have been found in not less than 14 species of stony corals. Some of these belong to a new family of curiously transformed animals, the CORALLOVEXIIDAE, of which the following forms were found during... |

| The genus Pseudoniphargus has long been considered monospecific. Its unique species, Ps. africanus, was supposed to occur on both sides of the Mediterranean, on the Atlantic side of the Iberian peninsula, on the Azores, and on Madeira, in localities ranging from the sea shore to more than 1000 m of altitude, and covering almost the entire natural salinity range (0-36‰). A taxonomie revision revealed that at least nine named species and several unnamed forms (of which insufficient material is available) hide under the name Ps. africanus, each with a narrow ecological and geographical range. The evolutionary scenario of the members of the genus is discussed at some length: they are presumably of marine origin, and got adapted to conditions of continental... |

| The Lamippidae form a rather homogeneous family of copepods endoparasitic on octocorals. The great majority of the species (17 out of 24) is described from the Mediterranean Sea. These species are relatively well-known, thanks to the efforts of DE ZULUETA (1908, 1910, 1911) and BOULIGAND (various papers, summarized in BOULIGAND, 1966). Outside the Mediterranean, Lamippidae have only incidentally been recorded, from the eastern Atlantic (European coasts, Sierre Leone), Indonesia, the Red Sea, and the Antarctic (references in HUMES, 1957, BOULIGAND, 1960, and STOCK, 1972). Not a single species was recorded hitherto from the western Atlantic or Caribbean region. Entire specimens were studied and measured in lactophenol; the appendages were dissected and... |

| Sixteen species of coastal or shelf Pycnogonida have been recorded from Madagascar, the Comoro Islands, and Mauritius. Two of these, Nymplion crosnieri and Pallenoides opuntia, are new to science. The ranges of Nymphon arabicum, N. setimanus, Parapallene hodgsoni, Anoplodactylus digitatus, A. versluysi, Endeis meridionalis and E. clipeata are considerably extended. Ascorhynchus corderoi, only known from Brazil, was found in Mauritius. In the light of recent work, Achelia nana may be identical with the wide-spread A. echinata. The original description of Nymphon arabicum is corrected, after re-examination of the types. A review of all uniunguiculate Nymphon-s is given. Anoplodactylus digitatus is synonymous with A. investigatoris and A. saxatilis (new... |

| A new species representative of a new genus of Copepoda is described. It belongs to the subfamily Cletopontiinae of the family Asterocheridae (Cyclopoida siphonostoma). The new genus is chiefly characterized by the 2-segmented nature of the endopodites of legs 3 and 4, by the absence of an exopodite in the posterior antenna, and by the strongly developed tergum of the 2nd metasomite, giving the animal a shield-shaped appearance. Only the female sex of this copepod has been found; it is an associate of the hermatypic coral Montastraea cavernosa (L.) on the South coast of Curaçao (Netherlands’ Antilles), in depths from 4 to 40 meters. |

| Up to now, the crustacean order Thermosbaenacea contained two genera with only six valid species, five from the panmediterranean region, one from Texas. Two new members of this curious group of “living fossils” have been discovered in the West Indies. The one, from two deep wells not far from the sea coast in Saint Croix (U.S. Virgin Islands), belongs to an undescribed species of the amphiatlantic genus Monodella, and is called M. sanctaecrucis. The other was found in several localities in Curaçao (Netherlands’ Antilles), in coral débris of rubble walls on the shore; it belongs to a new genus, Halosbaena showing several remarkable adaptations, e.g. having a uniramous first pereiopod and reductions in the maxilliped. The presence of very numerous... |

| Dr. Ernst Frederik Jacobi, who was a member of the Editorial Board of this journal for exactly 20 years, reached the age of 65 on September 11, 1973 and retired. Dr. Jacobi was appointed Director of the Amsterdam Zoo (officially: of the Royal Zoological Society “Natura Artis Magistra”) on April 1, 1953, in succession to Dr. A. L. J. Sunier. The function of Director of the Zoo automatically means also the membership of the Editorial Board of “Bijdragen tot de Dierkunde”. This periodical was published by the Royal Zoological Society until vol. 28 of 1949 (the last volume edited by Dr. Jacobi’s predecessor), but owing to the difficult financial situation of the Society, its publication was interrupted from 1949 to 1959, when vol. 29 appeared. From this volume... |

| Groundwaters (in wells, springs, caves, macroporous interstitia...) of 29 Caribbean islands have been investigated. Only on the four islands off the coast of Venezuela (viz., Aruba, Curaçao, Bonaire, and Margarita) members of the suborder Ingolfiellidea (Crustacea, Amphipoda) have been encountered, altogether six species, of which three are described here for the first time. The zoogeographical implications of this limited range in the West Indies is discussed. |
