The genus Anolis, as defined by Dumeril and Bibron, embraces a 

 great number of species, differing widely in external characters, which 

 have been made the basis of generic and subgeneric characters by vari- 

 ous authors, especially by Fitzinger. In general, the species may be 

 distinguished into five groups. There are, first, those that possess a 

 caudal fin in the male sex; a few large species and one or two small 

 ones from the West Indies. Second, species Avith compressed tail, with 

 caudal crest of scales, and with smooth ventral scales; a moderate 

 number of species, chiefly from the West Indies, but several from Mexico 

 and Central America. Third, species with tail like the preceding, but 

 with keeled ventral scales; a few species characteristically West Indian. 

 Fourth, species without median superior crest of scales on the tail, 

 which is more or less round ; ventral scales smooth ; numerous species 

 from South America, Central America, Mexico, and a very few from the 

 West Indies. Fifth, tail like the last, ventral scales keeled; the major-
