The Snakes of this Family bear a very close superficial resemblance 

 to the TyphlopidcE^ from which they may be distinguished externally

 borders the lip, and by the enlarged praeanal.

This genus was referred by Jan to the TypJilojndce, but it does 

 not appear from his descriptions that he ever examined the dentition. 

 I therefore follow Garman (N. Am. Eept. p. 129, 1883) in placing 

 it in 'the present family, as, judging from external characters, it 

 appears to stand in the same relation to Glaucoma as H clmintliopMs 

 to Tiipldops.
