or one-tenth of the total length (without caudal; ; the length of the 

 head is nearly one-sixth of the total (without caudal). Snout with 

 the jaws equal in length ; cleft of the mouth rather narrow ; the 

 maxillary extending to below the anterior margin of the orbit. Eye 

 of moderate size, somewhat shorter than the snout, more than one- 

 fifth of the length of the head. The length of the pectoral is much 

 less than one-half of the distance of its root from the ventral, and 

 that of the ventral is one-third or nearly one-third of the distance 

 of its root from the anal. The least depth of the tail is one-half of 

 the distance between dorsal and caudal fins. Caudal emarginate. 

 Yellowish -olive, body with numerous faint spots, each spot being 

 composed of minute dots. Operculum silvery.

 in length ; cleft of the mouth rather narrow ; the maxillary extend- 

 ing nearly to below the front margin of the orbit. Eye of moderate 

 size, as long as the snout, one-fourth of the length of the head. 

 The length of the pectoral is considerably less than one -half of the 

 distance of its root from the ventral ; and that of the ventral is two- 

 fifths of the distance of its root from the anal. The least depth of 

 the tail is one-half of the distance between dorsal and caudal fins. 

 Caudal truncate. Yellowish -olive (in spirits) ; back powdered with
