The material studied was mainly collected during Dr. P. WAGENAAR HUMMELINCK’S voyages to the West Indies in the years 1936/37, 1948/49, 1955 and 1963/64. The specimens from the Netherlands Antilles have been studied by COBBEN 1960, and DRAKE & COBBEN 1960. The present contribution deals mainly with the older material from other islands and the specimens collected during the 1963/64 trip. Some of the identifications were done by Mr. L. VAN DIJK and Mr. H. DE VUYST, during predoctoral studies.
