THE HERPETOLOGY OF HISPANIOLA 13 



BUFO MARINUS (Linnaeus)' 



1758. Rana marina Linnaeus, Systema naturae, ed. 10, vol. 1, p. 211. 



1938. Bufo marinus marinus Mertens, Senckenbergiana, vol. 20, p. 332; Publ.

The report by Dr. Mertens of the finding of young individuals at 

 Rio Jaina seems to be proof that this introduced form has established 

 itself definitely in the Dominican Republic. A second locality, Monte 

 Cristi, is likewise recorded in the same publication. The Museum 

 of Comparative Zoology has a fine specimen, No. 22486, from the 

 latter place, while another, No. 22485, was collected in Santa Barbara 

 do Samana by W. J. Clench. 



Family HYLIDAE 



Genus HYLA Laurenti 



1768. Hyla Laurenti, Synopsis reptilium, p. 32 (type, H. viridis). 



Of the four species of tree toads occurring in Hispaniola, the com- 

 monest by far is the bony-headed Hyla dominicensis, which is found 

 about dwellings and on verandas in almost every town on the island. 

 Hence it appears in great numbers in every collection of natural-his- 

 tory specimens brought back from there. Somewhat less common 

 generally, but abimdant in certain localities, is Hyla pulchrilineata, 

 probably the most beautifully marked of the four. Hyla heilprini, 

 with its dagger-shaped prepollex, is as yet known only from Pacifi- 

 cador Province in the Dominican Republic. The giant Hyla vasta, 

 largest of all the hylas, is commoner than its former rarity in museum 

 collections would indicate.
