The Antillean island of Jamaica is inhabited by 17 native species of frogs and three introduced species. This anuran fauna has not been reviewed since 1940, and the present paper brings up to date the nomenclature of the Jamaican frogs, and in addition gives much new zoogeographic, altitudinal, ecological, and reproductive data on 16 native and two introduced species. New subspecies of Eleutherodactylus cundalli, E. gossei, and E. pantoni are described. The total native anuran fauna of Jamaica is discussed, both as far as its internal (within Jamaica) and external (other Antillean islands) relationships are concerned, and a zoogeographic picture of differentiation from two major evolutionary centers in Jamaica is presented in reference to the frogs of that island.
