without distinct median groove ; superciliary region faiutly 

 striated ; base of the intermaxillaries much depressed. Maxillary 

 entirely hidden by the prceorbital, which is scaly. Teeth very 

 small ; vomerine teeth none. The diameter of the eye is some- 

 what more than the width of the interorbital space, and one-half 

 of the length of the post-orbital portion of the head. Depth of 

 the body considerably less than the length of the pectoral fin, 

 which is more than the distance of the opercular margin from 

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

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

 in length, short, the last terminating at a great distance from 

 the root of the caudal. The origin of the anal is in advance of 

 that of the dorsal. Caudal fin forked. Scales not very small, 

 adherent. Green above, silvery below.

The free portion of the tail is subtetrahedral, scarcely higher 

 than broad, with a slight narrow longitudinal keel along the side. 

 The length of the head is contained thrice and a sixth in the total 

 length (without caudal) ; its upper surface flat, striated without 

 conspicuous median groove ; superciliary region striated ; base 

 of the intermaxillaries broad, slightly compressed ; maxillary 

 entirely hidden by the praeorbital. Teeth of moderate strength ; 

 vomerine teeth none. The diameter of the eye is a little less than 

 the width of the interorbital space, and one-half of the length of 

 the postorbital portion of the head. Body slightly compressed, 

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

 nearly equals the distance of the opercular margin from the orbit. 

 Tongue covered with tubercular asperities. Ventral fin midway 

 between the front margin of the eye and the root of the caudal.
