The Snakes of this Family bear a very close superficial resemblance 

 to the TyphlopidcB, from which they may be distinguished externally 



Skull of Glauconia macrolepis (after Peters). 



by the character of the nasal shield which, whether single or divided, 

 borders the lip, and by the enlarged prseanal.

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

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

 I therefore foUow 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 Glauconia as Hdminthojphis 

 to Typhlops.
