The height of the body is contained six or seven times in the total 

 length, the length of the head five times and a quarter to five times 

 and three-quarters. The head is higher than broad, its greatest 

 width being nearly one-half of its length. The eye is situated in 

 the anterior half of the head, its diameter being one-fourth of the 

 length of the head ; the width of the space between the eyes is about 

 one-half their diameter. The snout is obtuse, as long as the eye ; 

 the cleft of the mouth oblique, extending to below the front margin 

 of the orbit. The teeth of the outer series are enlarged ; canine 

 teeth none. A large pore behind the eye. The dorsal fins are not

 in the total (without caudal) ; it is one-fourth broader than high, 

 and as much longer than broad. The eyes occupy the second quarter 

 of the length of the head, and are distant from each other the entire 

 or the half length of their diameter. The snout is somewhat con- 

 vex ; the cleft of the mouth slightly obUque, and extending to below 

 the anterior margin of the orbit; it does not ascend to the level of 

 the eye. Teeth of the outer series enlarged. The fii^st dorsal lower 

 than the body ; caudal rounded ; the upper pectoral rays silk-like.
