anal fin very short ; caudal forked. Structure of the mouth without

 sheath. Gill-opening rather narrow, the attachment of the giU- 

 membrane to the isthmus takes place opposite to the prseopercular 

 angle. Pharj-ngeal teeth conical, 4 . 3 — 2 . 4. Peritoneum black.

The height of the body is somewhat less than the length of the 

 head, which is nearly one-fourth of the total (without caudal). 

 Snout of moderate length ; the maxiUary extends to below the front 

 margin of the orbit. The width of the iuterorbital space equals the 

 length of the snout ; the diameter of the eye is contained six times 

 and a half in the length of the head, and once and two-thirds in 

 that of the snout. Suborbital ring very narrow. The origin of the 

 dorsal fin is a little nearer to the end of the snout than to the root 

 of the caudal, and considerably in advance of the base of the ventral. 

 Anal fin twice as high as long. Pectoral rounded, terminating at a 

 great distance from the ventral, the hind margin of which is sub- 

 truncate. There are a few scales in the humeral region and on the 

 commencement of the lateral line. The anal sheath is formed by 

 large scales ; the remainder of the body is naked. Greenish above, 

 silvery below. 



Habitat ?
