Form bearing some resemblance to B\ caicnahts. Elongate, stout, com- 

 pressed. Head about one fourth of the total length, crown flat. Snout 

 broad, blunt, one and one half times the length of the orbit. Mouth of 

 medium size ; lower jaw longer, upper protractile. Teeth conical, in bands, 

 outer series larger ; pharyngeal with a shoulder, many of the median becom- 

 ing molars, like those of F. majalis. Eye large, less than five times in the 

 head, more than half of the width of the forehead. Dorsal originating little 

 in advance of half way from snout to end of tail, about six rays forward of 

 the origin of the anal ; base extending several rays farther back than that 

 of the latter ; upper margin convex ; hind angle acute. Anal elongate, 

 lower angle acute, hind margin concave. Caudal broad, length slightly 

 greater than that of the base of the dorsal, two thirds of the head, trun- 

 cate. Ventrals small, not reaching the anal. Pectorals medium, reaching a 

 vertical from base of ventrals. Intestine short, extended, reaching nearly to 

 end of anal fin. 



Olivaceous, lighter beneath, opercle silvery ; a brownish spot on the base
