Body rather deep, elongate, compressed, and greatest depth, though belly is 

 emaciated, about origin of anal. 



Head a little oblong, widest below, upper surface somewhat constricted, of 

 more or less equal depth, and anterior profile steep. Snout broader than long and 

 with a convex surface, its profile steep. Eye high, deeper than long, and well
