 species in details of cephalic squamation.

 edge; rostral a little less than two sevenths the 

 width of the head, not extending backward to the 

 line of the eyes; details of head shields as shown

Typhlops tenuis Salvin. 



Salvin, Proc. Zool. soc. London, 1S60, p. 454. Boulenger, Cat. snakes Brit, mus., 1893, 1, p. 28. 

 Rosen, Lunds univ. arsskrift, 1911, 7, no. 5, p. 37. 



Rosen found a single specimen which he identified with this species at Mastic 

 Point, Andros Island. It had, however, twenty-two rows of scales about the 

 body instead of eighteen; and as this character is not variable among many 

 Typhlopidae, T. tenuis among them, there is ground for reasonable doubt as to 

 the correct identification of the species. Rosen does not mention that he had 

 other specimens for comparison. The species is one which ranges through 

 southern Mexico and Guatemala. 



Typhlops rostellatus Stejneger. 

 Stejneger, Rept. U. S. nat. mus. for 1902, 1904, p. 686, figs. 146-147. 



A species peculiar to Porto Rico, which upon that island takes the place of 

 its close relation, T. platycephalus Dumeril & Bibron from Martinique, and T. 

 dominicana Stejneger from Dominica. There yet remain many islands from 

 which representatives of this group of species have not yet been described, but 

 upon which they undoubtedly exist.
