335 



1-2; temporals, 1-2; eye contained twice in its distance from tip of 

 snout; rostral twice as broad as high; labials eight above, 4 and 5 

 entering eye; lower labials ten, five in contact with anterior chin 

 shields, which are shorter than the posterior; nasal separated from 

 loreal by prefrontal, which is broadly in contact with second labial. 

 Dark bluish, lighter on sides. A black line through eye; upper labials 

 white. Belly light gray anteriorly to dark bluish grey posteriorly. 

 "Only the type has been seen. It is evidently allied to catesbyi." 

 Dimensions: Head and body, 704 mm.; tail, 486 mm. 

 The head of this specimen has been twisted and bent, but the pro- 

 portions and relationships of the various scales are perfectly distinct.

This species seems to be the rarest in point of numbers of the three 

 occupying the mainland of Hispaniola. Its range is likewise limited, 

 for it is definitely recorded only from Haiti itself.
