THE HERPETOLOGY OF HISPANIOLA 7 



duced from Africa with the traffic in slaves, has now become estab- 

 lished in tropical America. 



The same is true of Hemidactylus mabouia. Another gecko, Sphaero- 

 dactylus cinereus, is one of the commonest species in Cuba, whence it 

 was probably transported to southern Florida, Navassa, and Haiti. 

 The slipperyback, Mabuya mabouya sloanii, represented very rarely 

 in Hispaniola, is considered by Dr. Dunn (1936, p. 546) to be the same 

 as the form occurring in the southern Bahamas, Jamaica, the Virgin 

 Islands, Mona, and Puerto Rico. Typhlops lumbricalis is a species of 

 which much more Hispaniolan material is needed before an ultimate 

 decision as to its status can be made. Crocodylus acutus is found in 

 Cuba, Hispaniola, Jamaica, Florida, and Central America. 



SPECIES ERRONEOUSLY RECORDED FROM HISPANIOLA 



The type of Spelerpes infuscatus Peters, now in the Berlin Museum 

 (No. 6556), supposedly from "Hayti," has been positively identified 

 by Dr. E. R. Dunn as Oedipus lineolus Cope and hence must have 

 come from Mexico (Dunn, 1926). The intensive collecting done 

 during the past few years leaves little expectation of finding any 

 endemic tailed amphibian in the West Indies. 



Hispaniolan records of Eleutherodactylus auriculatus Cope are 

 undoubtedly based on misidentifications of the several small frogs 

 that bear quite a close resemblance to the rather variable true auricu- 

 latus of Cuba. 



Boulenger's record of a Dendrobates trivittatus (1882, p. 145) from 

 "S. Domingo" is probably based on an incorrect locality record, as 

 no true Dendrobates is to be expected so far out of its range.

KEY TO THE GENERA OF HISPANIOLAN FROGS AND TOADS 



a 1 . No teeth (family Bufonidae) Bufo (p. 8) 



a 2 . Teeth on upper jaw and roof of mouth. 



b l . Diapophyses of sacral vertebrae dilated (family Hylidae) Hyla (p. 13) 



b 1 . Diapophyses of sacral vertebrae cylindrical or slightly dilated 

 (family Leptodactylidae) 



c 1 . Sternum without a bony style Eleutherodactylus (p. 24) 



c 3 . Sternum with a bony style Leptodactylus (p. 84) 



One genus, Leptodactylus, is represented by a single species on 

 Hispaniola. Four species of Hyla are known, while Eleutherodactylus 

 has 24 well-marked species at present and the probability of others 

 yet to be discovered. Bufo now has two species, B. marinus having 

 recently been introduced in the Dominican Kepublic.
