| In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella. Transferred to Tethysbaena are: M. argentarii Stella, 1951; M.... |

| Two new stygobiont amphipods are described from anchialine caves located in the Jaragua region (Pedernales Prov., Dominican Republic, Hispaniola). Ottenwalderia kymbalion gen. et sp. nov. is the first lysianassoid known to have penetrated into completely fresh waters, and the fourth colonizing hypogean habitats. Bahadzia jaraguensis sp. nov. is the second representative of this West Indian thalasso-stygobiont genus to be reported from fresh waters; it exhibits the most troglomorphic aspect (i.e. elongation of first antennae and sixth pereiopods) recorded for the genus. Its diagnosis is complemented with a key to the species of the genus Bahadzia. The in situ swimming behaviour of both taxa is briefly described. It is postulated that both amphipods share a... |

| During the Amsterdam Expedition to the Dominican Republic five samples containing three species of anthurid isopods, two of them new to science, were collected, viz. Cyathura (Stygocyathura) salpiscinalis Botosarieanu & Stock, 1982; C. (S.) broodbakkeri n. sp.; and C. (C.) tridentata n. sp. The latter is the first hypogean representative of Cyathura s. str. from the Caribbean. All the known Hispaniolan species, C. (S.) motasi Botosaneanu & Stock, 1982, excepted, are found in a limited area that during the Tertiary was covered by an inland sea. Here a rapid speciation occurred in two isolated lakes that were cut off from the sea, and from each other, as a result of uplift in this valley. |

| During the austral summer seasons of 1963-1964 and 1964-1965, and during the austral winter season of 1967 Prof. Dr. J.S. Zaneveld made collection expeditions to the western Ross Sea. In 1965 collections were also made from the U.S.C.G. icebreaker ‘Glacier’, around the western Ross Sea and around the Balleny Islands. During the same cruise Macquarie Island was visited. Most collecting was carried out by means of scuba-diving. Prof. Zaneveld was accompanied on these expeditions by W.I. Simmonds (1963-1964), J.M. Curtis (1964-1965), J.K. Fletcher (1964- 1965), D.M. Bresnahan (1967), and L.L. Nero (1967), during these periods students at Old Dominion University, Norfolk, Virginia, U.S.A. In the harsh Antarctic environment the algae discussed in the present... |
