Malacolog Version 4.1.1

A Database of Western Atlantic Marine Mollusca

The Academy of Natural Sciences, Philadelphia

Malacolog is a database for research on the systematics, biogeography and diversity of mollusks. Malacolog attempts to document all names that have ever been applied to marine mollusks in the Western Atlantic from Greenland to Antarctica. The database was described in Rosenberg, G. 1993. A database approach to studies of molluscan taxonomy, biogeography and diversity, with examples from Western Atlantic marine gastropods. American Malacological Bulletin 10:257-266. Malacolog now includes all mollusks, not just gastropods. Gastropod species have the most complete coverage followed by bivalves, while polyplacophorans, aplacophorans, monoplacophorans and scaphopods are a work in progress, and cephalopods include only a small subset of names. Malacolog also includes dictionaries for gender of names, a bibliography and browse lists for families and geographic ranges, as well as search help and an information model.
