Scales of moderate size, very thin and deciduous. The dorsal fin 

 commences before the eye. Teeth minute, of equal size. The height 

 of the body is contained twice and a half in the total length (without 

 caudal), the length of the head thi'ice and three-fourths. The greatest 

 depth between the anal fin and the straight portion of the lateral line 

 is less than the length of the head. Snout with the jaws subequal 

 anteriorly, as long as the diameter of the eye, which is two-ninths 

 of the length of the head. The length of the maxillary is two-fifths, 

 that of the mandible rather more than one-half of that of the head. 

 Eyes separated by a very narrow, bony, prominent, naked ridge, the 

 lower being slightly in advance of the other. Lateral line with a 

 subsemicircular curve above the pectoral. The dorsal aiul anal are 

 continued on to the root of the caudal ; the longest dorsal rays are 

 somewhat behind the middle of the fin, where they are half a.s long 

 as the head, and rather shorter than the pectoral. The rays of the
