HAITI AND SAN DOMINGO. 227 



Porto Rico. A sixth species now described occurs apparently about Guanta- 

 namo only. 



The distribution of the species of Gonatodes, Sphaerodactylus, Anolis, Lio- 

 cephalus, Celestus, Ameiva, .\mphisbaena, Typhlops, Epicrates, Tropidophis, 

 Alsophis, and Leimadophis may all be found by referring to.the tables of distri- 

 bution. The distribution of each of these genera includes Cuba, being repre- 

 sented there by pecuHar island species, as is the prevalent mode of occurrence 

 for tliese genera throughout that portion of the West Indies in which each occurs. 



In conclusion, then, we may say that Cuba has sixty-three species of reptiles 

 and amphibians, of which fifty are peculiar to the island. The proportion is 

 probably larger than this, since a number of the records of Cuban species in 

 Haiti will probably be found to represent distinct island races when comparisons 

 of freshly collected and well-preserved material are possible. 



Jamaica. 



No new species have been added to the fauna of Jamaica since I published 

 my Notes on the herpetology of Jamaica (Bull. M. C. Z., 1910, 52, p. 273-302, 

 pi. 1-2). Thirty-three species are recorded from the island ; and of these, twenty- 

 six are peculiar. It is not necessary to go further into a special discussion of the 

 Jamaican fauna, since I have nothing to add to the remarks in the paper referred 

 to. 



Haiti and San Domingo. 



For the purpose of convenience these islands have been mentioned as Haiti 

 throughout the paper; and, as the fauna in the two republics seems to be rather 

 homogeneous, there is no special reason for not using this old Indian word, which 

 was originally the name for the entire island. 



From Haiti alone, of all the Antilles, has been reported a tailed amphibian, — 

 Spelerpes infuscatus Peters, — and this fact, coupled with the occurrence of Hyla 

 pulchrilineata Cope, is significant of a relationship with the Mediterranean region, 

 such as has already been suggested by Scharff. Besides the occurrence of these 

 two anomalies, the fauna of Haiti is interesting as bearing out the belief that Cuba 

 and Jamaica have never been joined together, and any similarity of fauna that the 

 two islands show many be explained by the fact that each of them has at differ- 

 ent times been connected with both Haiti and Central America. Thus the gen- 

 era Bufo, Gonatodes, Liocephalus, and Amphisbaena are all found in Cuba and
