Geographic variation in two species of Hispaniolan Eleutherodactylus, with notes on Cuban members of the ricordi group

SHREVE & WILLIAMS (1963) have discussed at some length the relationships between several named forms of West Indian Eleutherodactylus, including E. pictissimus Cochran and E. weinlandi Barbour. The former had been long known from only the type specimen from the Massif de la Hotte on the Tiburon Peninsula of Haiti, and the latter from the Peninsula de Samana and extreme eastern and northern Republica Dominicana. Extensive Haitian collections amassed by Dr. ERNEST E. WILLIAMS for the Museum of Comparative Zoology (MCZ) and large lots of specimens collected by the writer and parties in the years 1962 and 1963 have elaborated the distribution of these two species, and have made it possible to ascertain geographic variation in both. In addition to my own collections, I have been able to study those of the American Museum of Natural History (AMNH), Museum of Comparative Zoology, United States National Museum (USNM), and the Museum of Zoology, University of Michigan (UMMZ); for the privilege of examining these specimens I wish to thank Mr. CHARLES M. BOGERT and Miss MARGARET BULLITT, Dr. ERNEST E. WILLIAMS, Dr. DORIS M. COCHRAN, and Dr. CHARLES F. WALKER and Mr. GEORGE R. ZUG. Miss PATRICIA A. HEINLEIN, and Messrs. RONALD F. KLINIKOWSKI, DAVID C. LEBER, DENNIS R. PAULSON, and RICHARD THOMAS have been enthusiastic assistants in my Hispaniolan ndeavors, and they deserve my most sincere thanks for their help. The figures in the present paper are the work of Mr. LEBER and Mr. KLINIKOWSKI, who again have made significant contributions to the effort.
