of the pectoral, which, again, is somewhat less than the distance of 

 the oi)erciilar raargin from the orbit. Ventral fin nearer to the head 

 than to the root of the caudal. The middle and hinder dorsal and 

 anal rays snbeqnal in length, short, the last terminating at a con- 

 siderable distance from the root of the caudal. Caudal fin emarginate. 

 Scales vciy thin and small, deciduous ; there are about sixteen longi- 

 tudinal series between the origin of the dorsal fin and the lateral 

 line.

The free portion of the tail is compressed, much deeper than 

 broad. The length of the head is one-third of the total (without 

 caudal) : its upper surface with a rather shallow median groove 

 which widens in front; superciliary and parietal regions coarsely 

 striated ; base of the iutermaxiUarics depressed, maxillary two-thirds 

 hidden by the prseorbital. Teeth strong, bent backwards ; vomerine 

 teeth none ; tongue smooth. The diameter of the eye is two-thirds 

 of the width of the interorbital space, and two-sevenths of the length 

 of the postorbital portion of the head. Rody strongly compressed, 

 its depth being less than the length of the pectoral, which equals 

 the distance of the opercular margin from the orbit. Ventral fin 

 midway between the hind margin of the eye and the root of the 

 caudal. The middle and hiader dorsal and anal rays subequal in 

 length, short, the last terminating at a considerable distance from 

 the root of the caudal. Caudal fin subtnmcate. Scales not very 

 small ; there are about twelve longitudinal series between the dorsal 

 fin and the lateral line.
