D. 11. A. 8. L. lat. 34. L. transv. 5|/5. 



Structure of mouth and snout as in T. falcifer, to which this 

 species'is extremely similar. Barbels foui, very &mall. Eye small, 

 situated somewhat behind the middle of the length of the head. 

 There are three longitudinal series of scales between the- lateral line 

 and the root of the ventral fin. The height of the body equals the 

 length of the head, which is two-ninths or one-fifth of the total {with- 

 out caudal). Origin of the dorsal fin in advance of that of the 

 ventral, opposite to the tenth scale of the lateral line. Anterior 

 dorsal rays more or less prolonged in adult examples. Caudal fin 

 deeply forked. A narrow, yellowish, longitudinal band runs along 

 the side of the body, above the lateral line.

D. 11. A. 8. L. lat. 32-33. L. transv. 4|/4. 



Structure of mouth and snout as in T. falcifer, from which it 

 differs in having larger scales. Barbels four, very small. Eye 

 small, situated somewhat behind the jniddle of the length of the 

 head. There are two and a half longitudinal series of scales 

 between the lateral line and the root of the ventral fin. The height 

 of the body is contained four times or thrice and three-fourths in 

 the total length (without caudal), the length of the head four times 

 and a half or five times. Origin of the doi-sal fin in advance of that 

 of the ventral, opposite to the ninth scale of the lateral line. An- 

 terior dorsal rays scarcely prolonged in adult examples. Caudal fin 

 forked. Coloration uniform. 



Java. 

 a. Young, one of the typical specimens. From Dr. Bleeker's Col- 

 lection. 

 h-e. Fine adult (nine inches) and half -grown specimens. Purchased
