No. 8 — The Relationships Of Four Small Hispaniolan Eleutherodactylus (Leptodactylidae) By Albert Schwartz 10,000 SW S4th Street Miami, Florida 33143 Perhaps the most confusing group of the genus Eleutherodactylus in the West Indies is that composed of the small to minute frogs of Hispaniola, none of which has a snout-vent length in excess of 25 mm. To this assemblage belong E. minutus Noble 1923, E. abbotti Cochran 1923, E. audanti Cochran 1934, and E. haitianus Barbour 1942 (= E. intermedins Cochran 1941, preoccupied). E. abbotti was described from Laguna, Samana Province, RepubUca Dominicana, E. audanti from Peak la Selle (= Mont la Selle), Dept. de I'Ouest, Haiti. The remaining two forms were described from the interior uplands of the Cordillera Central in La Vega Province (Repiiblica Dominicana), minutus from near Paso Bajito, Jarabacoa-Constanza Trail, and haitianus from Loma Rucilla, 8C00 to 10,0C0 feet. Although minutus and haitianus are still known only from various localities in the Cordillera, abbotti has been reported from many localities in the Repubhca Dominicana and Haiti. E. audanti is here reported for the first time from outside of the Massif de la Selle. Shreve and Wilhams (1963: 320-323) discussed at some length the situation of the species audanti and abbotti in the Port-au-Prince region. Conclusions drawn from my own experience in the field in both Haiti and the Republica Dominicana in 1962 and 1963 differ from theirs, and are drawn in part from a large body of fresh material from critical localities both outside and within the range of their particular study. Through the courtesy and cooperation of the following curators, I have been able to study specimens of this group of frogs : Ernest E. Williams, Museum of Comparative Zoology (MCZ) ; Doris M. Cochran, United States National Museum (USNM) ; and Charles M. Bogert and Margaret Bullitt, American Museum of Natural History (AMNH). Specimens in my own collection are designated Albert Schwartz Field Series (ASFS). In the field in Hispaniola I had the capable assistance of Patricia A. Heinlein and Ronald F. Klinikowski, Dennis R. Paulson, David C. Leber, and Richard Thomas. To all of them I express my sincere thanks for their interest in these small frogs. The illustrations for the present paper are the work of Klinikowski and Leber; they again merit my gratitude for their endeavors.
