THE HERPETOLOGY OF HISPANIOLA 



difficult to find a satisfactory basis for the separation of niger and 

 protenus as subspecies, since so many intergrading specimens now 

 exist in the lowlands lying between the areas once separated by 

 stretches of sea. 



DISTRIBUTION OF GREATER ANTILLEAN GENERA 



In table 1 are listed the genera occurring on the neighboring islands 

 of the Greater Antilles. Hispaniola has 19 genera in common with 

 Cuba, Cuba has 10 genera that Hispaniola lacks, but, on the other 

 hand, Hispaniola has 13 genera not found in Cuba.
