 Dorsal profile, especially from nape, strongly ascending. Height 

 2.8, 3.6 in length with caudal. Head about 3'/2» A^U in length 

 with caudal. Eye 2^', o"" somewhat more, longer than snout 

 and interorbital space and equal to postorbital space. Snout 

 obtuse. The upper jaw overlapping the lower. A maxil- 

 lary barbel above corner of mouth, divided into fringes, the 

 longest of which are longer than the eye. Origin of dorsal 

 opposite to nth scale of lateral line, separated by 13 or 14 

 scales from occiput, slightly behind origin of ventrals, about 

 in the middle of a line connecting end of snout and root of 

 caudal. Dorsal concave. Fourth spine osseous, of moderate 

 strength, strongly serrated, its stiff part nearly equal to head. 

 Anal emarginate, depressed, far distant from caudal, its height 

 about equal to head without snout. Ventrals subequal to pec- 

 torals, their base separated by 5 scales from 9th scale of lateral 

 line, nearly reaching anal. Pectorals somewhat shorter than 

 head, nearly 6 times in total length with caudal. Least height of 

 caudal peduncle more than I'/a in its length, somewhat more 

 than twice in length of head, surrounded by 16 scales. Silvery, 

 back darkish. Length 1 14 mm.
