the prceorbital. Teeth of niodorate size ; vomerine teeth none. The 

 diameter of the eye is somewhat more than one-half of the width 

 of the interorbital space, and contained twice and three-fourths in 

 the length of the postorbital portion of the head. Body compressed, 

 its depth being about equal .o the length of the pectoral fin, or to 

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

 nearly midway between the root of the caudal and the front margin 

 of the orbit. 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 forked. Scales thin and 

 very small, adherent.

The free portion of the tail is slightly depressed, as high as broad ; 

 lateral line not terminating in a keel. The length of tbe liead is 

 two-fifths of the total (without caudal) ; its upper surface deeply 

 striated, with a rather shallow median groove ; base of the inter- 

 maxiUaries strongly depressed, maxillary three-fourths hidden by 

 the prseorbital. Teeth of moderate size ; vomerine teeth none ; 

 tongue smooth. The diameter of the eye is three-fourths of the 

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

 postorbital portion of the head. Body .subcyhndrical, its depth 

 being much less than the length of the pectoral tin, which is more 

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

 fin nearly midway between the root of the caudal and the front margin 

 of the orbit. 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 ; anterior rays very long. Caudal fin forked. 

 Scales thin, not very small, adherent,

The free portion of the tail is not compressed, subtrihedral, the 

 back of the tail being broad and depressed. The length of the head 

 is nearly one-third of the total (without caudal) ; its upper surface 

 with a broad, shallow median groove, tapering behind, widening in
