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 material may justify the publication of this list of localities.
