146 CYPKINIDJi. 



slightly convex ; upper jaw slightly overlapping the lower ; barbel 

 very small. The height of the dorsal fin is two-thirds of the depth 

 of the body ; its origin is opposite that of the ventral, and equally 

 distant from the root of the caudal and the end of the snout. Anal 

 fin of moderate size, higher than long ; caudal deeply forked. 

 Silvery, greenish above ; a large, cuneiform, black spot on the 

 lateral line above the hinder part of the anal fin. Tips of the 

 caudal lobes black, with white extremities. 

 Ceylon ; Cochin.

Valenciennes and other naturalists have overlooked the barbel in 

 this species. It appears that in some (male?) individuals the 

 middle dorsal rays are produced into long filaments, at least at 

 certain seasons. 



Surgeon Day believes that Leuciscus mahecola, Cuv. & Val. xvii. 

 p. 305, pi. 502, is the young of this species ; I hesitate to adopt 

 this opinion, because the black caudal spot is more advanced in 

 B.Jllamentosus than in the figTire oi L. mahecola. 



cc. No osseous dorsal ray.

None of the dorsal rays osseoas. Mouth small ; barbel con- 

 siderably longer than the eye. Snout of moderate length, rather 

 obtuse in front, longer than the eye, with the jaws equal. The 

 height of the body is somewhat more than the length of the head, 

 and one-fourth of the total (without caudal). There are two 

 longitudinal series of scales between the lateral line and the root 

 of the ventral. The dorsal fin commences in advance of the 

 ventral, nearer to the end of the snout than to the root of the 

 caudal. A black streak runs from the snout, through the eye, to 

 the middle of the root of the caudal ; a red band above the black 

 one during life. Each caudal lobe with an oblique black cross band.
