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

 The length of the head is contained twice and a half or twice and 

 four-fifths in the total (without caudal) ; its upper surface flat, with 

 a. rather shallow median groove of moderate width ; superciliary 

 region striated ; base of the intermaxillaries depressed, maxillary 

 only one-third hidden by the praeorbital. Teeth rather small ; vomer- 

 ine teeth none. The diameter of the eye equals the width of the 

 interorbital space, and is one-third or rather less than one-third (>f 

 the length of the postorbital portion of the head. Body broad, sub- 

 cylindi'ical, its depth being considerably less than the length of the 

 pectoral fin, which equals the distance of the opercvJar margin from 

 the orbit. Ventral fin nearly midway between the eye and the 

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

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

 the root of the caudal. Caudal fin rounded. Scales rather small, 

 adherent. A small, round, deep-black spot on the root of the caudal
