ZOOLOGICAL GEOGRAPHY. 
[part hi. 
Reptiles and Amphibia. — These classes not having been 
systematically collected, and the numerous described genera not 
having undergone careful revision, little trustworthy information 
can be derived from them. The following enumeration of the 
chief groups hitherto noticed or described, will, however, show 
very similar features to those presented by the birds — a general 
relation to Neotropical forms, a more special relation to those 
of Central America and Mexico, and a considerable number of 
peculiar types. 
Snakes. — Arrhyton (Calamarikke) from Cuba, Hypsirhynchus 
from Barbadoes, Cryptodams from Cuba, Ialtris from Hayti, and 
Coloragia from Cuba (all Colubridae), have been described as 
genera peculiar to the Antilles. Fhylodryas and Dromicus 
(Colubridae) are Antillean and Neotropical ; Ahmtulla. (Den- 
drophidae) has the same distribution but extends to tropical 
Africa ; Epicrates and Corallus (Pythonidae) are Neotropical 
and Antillean; while Chilaboihrus from Jamaica and Ungalia 
from Cuba and Jamaica (both Pythonidae) are found elsewhere 
only in Central America and Mexico. There appear to be no 
Crotalidae except an introduced species of Craspedocephalus in 
St. Lucia. 
Lizards are more numerous. Ameiva (Teidae) is found all 
over America. Gerrhonolus (Zonuridae) is Neotropical and! occurs 
in Cuba ; Gymnopthalmus is South American and Antillean. 
Of Scincidae seven genera are noted. Celestus (with 9 species) is 
peculiar to the Antilles ; Camilia (1 species) to Jamaica, Panoplus 
(1 species) and Embry opus (1 species) to Hayti; Diplogossus is 
Antillean and South American ; while Plestiodcn and Mabouya 
are cosmopolite. Of Geckotidae there are four genera ; Phyllo- 
dactylus and Hemidactylus which are cosmopolite ; Sphcerodactylus 
which is wholly American ; and Gubina found only in Martinique 
and Brazil. Of Iguanidse there are six genera ; Anolis , which 
ranges all over America; Polychrus, which is Neotropical; 
Iguana and Liocephalus w T hich are South American; Tropeduius 
found in Cuba and Brazil ; and Cyclura only known from 
Jamaica, Cuba, and Central America. 
Amphibia. — The genus Trachyeephalus, belonging to the
