THE preparation of bibliographies is often a thankless task, although few would deny their importance. The present example covers the literature of the larvae of Decapod Crustacea (excluding the Euphausiacea) up to May 1939. It comprises three sections-an alphabetical list of authors, a classified catalogue in which the literature is arranged zoologically, and an index to genera. Some eight hundred titles are recorded.
