The nominal Hispaniolan anole species, Anolis hrevirostris Bocourt, is considered to be comprised of four distinct parapatric sibling species: A. hreviros-tris, A. caudalis. A. wehsteri. and A. marron. These species and the subspecies oi A. hrevirostris are described. INTRODUCTION Anolis hrevirostris Bocourt is a rather small and stocky anoline lizard that occurs within an irregular range in xeric habitats on Hispaniola and associated islets. In 1870 Bocourt named Anolis hrevirostris from Haiti. The name fell into disuse and obscurity, with specimens o{ A. hrevirostris generally being included with A. dominicensis Reinhardt and LUtken. Cochran (1941) described and named two satellite island subspecies oi A. dominicensis: wetmorei from Isla Beata, Dominican Republic; and caudalis He de la Gonave, Haiti. Barbour (1937) first combined A. dominicensis with A. disticlms Cope. This combination was followed by Mertens (1939) who resurrected hrevirostris as a subspecies oi A. distichus from the vicinity of Barahona in southwestern Dominican Republic. Ernest E. Williams, at the Museum of Comparative Zoology at Harvard University, recognized that some of the forms in Haiti and the Dominican Republic associated with A. distichus actually per-tain to another similar species, A. hrevirostris (the differential char-acters were reported in Schwartz, 1968). Named forms correctly associated with A. hrevirostris are caudalis Cochran and wetmorei Cochran. Webster and Burns (1973) used electrophoretic observa-' University of Kentucky. Albert E.
