Caribbean Land Molluscs: Subulinidae and Oleacinidae

This publication represents a continuation of a previous article on the Caribbean Vertiginidae (this series, Vol. X, 1960, No. 41), and it will follow the same arrangement as the former. This will not only add to the uniformity of the series, it will, furthermore, make it simpler to compile individual faunal lists from any locality situated within the region treated here. Yet another continuation will follow this article, in which some smaller families with their representatives in the Caribbean region will be listed. The photographs (Plates X E and XI I excepted) were again taken by Dr. P. WAGENAAR HUMMELINCK, with the technical assistance of Mr. H. VAN KOOTEN, at the Zoological Laboratory of the State University, Utrecht.
