The height of the body is contained twice and a fourth in the total 

 length (without caudal), the length of the head five times and a half. 

 The greatest depth between the anal fin and the straight portion of 

 the lateral line is much more than the length of the head. Scales 

 small, with the margins entire ; head entirely covered with very 

 small imbiicate scales, snout and ridge between the eyes naked ; 

 body entirely smooth. Lateral line with a low curvature above the 

 pectoral, the greatest depth of the curvature being less than the 

 width of the base of the pectoral. Snout shorter than the eye, the 

 diameter of which is one-fourth of the length of the head. Jaws 

 equal anteriorly, lips very thick ; maxillary rather shorter than the 

 eye. Upper jaw with a series of about thirteen closely-set, trun- 

 cated, incisor-like teeth on the bhnd side. Eyes separated hj a sharp 

 elevated ridge, their anterior margins being on the same level. The 

 dorsal fin commences a little behind the anterior margin of the eye, 

 and its distance from the caudal is rather less than one-hfJf of the 

 depth of the free portion of the tail. Dorsal and anal rays covered 

 with minute scales ; the dorsal rays about the sixtieth are the longest, 

 6wo-thirds as long as the head, and equal in length to the pectoral. 

 No prominent spine before the anal. GiU-rakers rather closely set, 

 very thin, pointed and short. Brownish, sometimes marbled v:'.th 

 darker.
