 DescrirMon of .spec/e.s.— (From Boulenger.) "Snout very 

 prominent, with a narrow, sharp, subcrescentic transverse edge 

 and inferior nostrils. Rostral large, its upper part longer than 

 broad and about three-fifths the width of the head, not extending 

 to the level of the eyes, its lower part as broad as long; nasal 

 nearly completely divided, the cleft proceeding from the first 

 labial; prseocular present, nearly as broad as the nasal or the 

 ocular, in contact with the second and third labials ; eyes distinct ; 

 prefrontal considerably enlarged ; four upper labials. Diameter 

 of body 50 to 68 times in the total length ; tail twice and a half 

 as long as broad, ending in a spine; 20 or 22 scales round the 

 body. Pale brown, lighter interiorly. ■ 

 "Total length 410 millim. 



"Philippines, Moluccas, North-west Australia." 

 Remarks. — Boulenger * records four specimens. One speci- 

 men, the type, is from the Philippines. Peters t gives two local- 

 ities on Samar, Loquilocun and Borongan. Here, he states, it is 

 called tuna. The types were collected by H. Cuming. I have 

 been unable to find this species, and there is no specimen in the 

 Bureau of Science collection. Boulenger gives Typhlops (Onij- 

 chocephalus) angusticeps Peters as a synonym, of this species. 

 An examination of Peters's figures J leads me to regard this as 

 an error. The presence of a subocular, as well as of other char- 

 acters, would seem to prohibit this association.
