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

 the opercular margin from the orbit. Ventral fin nearer to the head 

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

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

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

 Scales very thin and smaU, 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 comi)ressed, miich 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 froiit; superciliary and parietal regions coarsely 

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

 hidden by the praeorbital. 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. Eodj 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 hinder dorsal and anal rays subcqual in 

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

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

 small ; there are about twelve loiigitudinal series between the dorsal 

 fin and the lateral line.
