    Description: Symbiotic species, living within or on the surface of host organisms, may evolve a wide range of adaptations as a result of various selection pressures, host specificity of the symbiont and the nature of the symbiosis. In tropical marine coral reef ecosystems, palaemonid shrimps (Crustacea: Decapoda: Caridea) live in association with at least five different invertebrate phyla. Host switches between (distantly) related host groups, and the thereby associated selection pressures were found to play a major role in the diversification of these shrimp lineages, giving rise to various host-specific adaptations. Two lineages of palaemonid shrimp, which have switched from an ectosymbiotic association towards endosymbiosis, are studied for their morphological diversification and possible convergence. Special attention is given to the betweenphyla host switches involving ascidian and bivalve hosts, which are characteristic for these lineages. Using landmark-based (phylo)morphospace analyses and Scanning Electron Microscopy, the walking leg dactylus shape and the microstructures on these dactyli are studied. No specific bivalve- or ascidian-associated morphotypes were found, but morphological convergence in dactylus morphology was found in various species within the two studied clades with similar host groups. In addition, multiple lineages of bivalve-associated species appear to be morphologically diverging more than their ascidian-associated relatives, with ‘intermediate’ morphotypes found near host-switching events.

    Description: Species of the decapod family Palaemonidae are common components of tropical coastal waters and coral reefs. The majority of these species are symbionts of various invertebrate phyla. Despite a long history of research on their species diversity in the Dutch Caribbean, recent field expeditions have yielded much new information. Combined with examinations of specimens housed in Naturalis Biodiversity Center and information from literature, a comprehensive list of Dutch Carribean palaemonids is provided. Newly collected material was primarily identified via morphological analyses. Additional molecular phylogenetic analyses based on mitochondrial COI and 16S and nuclear Histone 3 (H3) genes were conducted in search of cryptic species on the one hand and to check conspecifity in species that were found on multiple host species on the other hand. In total, 46 species are here listed for the Dutch Caribbean of which 24 are here recorded for the first time for one of the islands. One species new to science was discovered and is herein described. Sixty new host associations are recorded. In light of biodiversity loss and increasing anthropogenic pressure on declining coral reefs, documenting the diversity of palaemonids and other coral reef species to provide baseline data takes on a new urgency.

    Description: During the DIVA-2 cruise (May 31 - July 4, 1994, see Desbruy\xc3\xa8res et al., 1994) and the PICO cruise (June 25 \xe2\x80\x93 July 11, 1998, N/O Nadir, PI: D. Desbruy\xc3\xa8res) to the Azores Triple Junction Area, two rare species of caridean shrimp were collected. Seven specimens of the pandalid Plesionika alexandri (A. Milne Edwards, 1883) were collected at the Lucky Strike hydrothermal vent field (37\xc2\xb020\xe2\x80\x99N), and one specimen of the pontoniine Periclimenes kornii (Lo Bianco, 1903), at the Menez Gwen hydrothermal vent field (37\xc2\xb050\xe2\x80\x99N). These hydrothermal vent fields are located on the Mid-Atlantic Ridge SW of the Azores. Both species of shrimp are only known from a few specimens. The original description of Plesionika alexandri was based on an incomplete specimen. It is now re-described on the bases of the present material

    Description: In this catalogue the type specimens of Decapod Crustacea in the collections of the Nationaal Natuurhistorisch Museum are listed in systematic order. Some lectotypes have been designated. The history of the collection is described. The first appendix lists all specimens in the dry collection collected before 1900. In the second appendix the pre-1900 sources of crustacean material in the collection are listed alphabetically; short biographies and portraits of collectors are given. An index to scientific names is added.

    Description: During the CANCAP-5 expedition to the Azores (1981) a new species of Bythocaris was found.\nThe new species is described and figured. It is compared with other members of the genus. A key to the species of Bythocaris is provided. The intra-specific morphological variation of B. payeri, B. leucopis and B. simplicirostris has been studied. The relevance of this intra-specific variation for distinguishing between species is discussed.

    Description: A note is presented on the crab Macrophthalmus (Macrophthalmus) ceratophorus Sakai, 1969, formerly only known from the holotype male specimen which was collected in Japanese waters. The species is redescribed on the basis of a large sample, collected from the Amirante Islands in the western Indian Ocean. All specimens were associated with the epizoic lepadid cirriped Octolasmis warwickii Gray, 1825, and an encrusting athecate hydroid.
