 more slender than that from Martinique ; it has narrower scales and not 

 nearly so many of them. In color the tendency is toward olive, more or 

 less uniform ; the brown blotches being almost obsolete in cases. Belly 

 whitish to yellowish, with few or no puncticulations. Individuals vary 

 from light olive with white belly to dark olive-brown with yellowish 

 ventrals. 



The Martinique serpent is brown rather than olive ; the brown blotches 

 are more distinct, and the puncticulations on dorsals and outer portions of 

 ventrals are abundant ; the bellies are yellow. Individuals vary from 

 yellow to black.
