South American Ground Lizard (Ameiva ameiva). (IHC) Anolis cristatellus. —This Puerto Rican lizard (Fig. 12) was first reported from "Biscayne Key" (=Key Biscayne). Dade County, by Schwartz and Thomas (1975). Brach (1977) provided information on its distribution and population density on Key Biscayne. re- porting it to occupy a four block area in the vicinity of West Enid Drive on the southern portion of the key. The population is increas- ing slightly in the occupied area, and a secondary introduction from it is now present and flourishing on the Crandon Park Zoo grounds, also situated on Key Biscayne. In 1976 we became aware of a new locality for this lizard in the vicinity of 97th Street and 57th Avenue (Red Road). This population may have resulted from a separate introduction (not from the Key Biscayne populations), be- cause adult males have a brighter, more orange dewlap. A secondary introduction is known by us to have been made a few blocks to the west. Anolis cybotes.—This Haitian lizard (Fig. 13) was first reported in south Florida by Ober (1973) on the basis of a self-introduction at the author's home in northeastern Dade County. Although Ober (1973) reported a high probability of a spread of this anole from the original site of introduction via trash removal, we are unaware of any secondary introductions. Anolis cybotes is still abundant at the original site of introduction, but it appears to have spread only into the immediate vicinity. Anolis distichus.—Three subspecies of this lizard have been re- ported from the Florida mainland (Smith and McCauley 1948; King and Krakauer 1966; Schwartz 1968). These are A. d.
