Snout somewhat pointed in front, rather produced, the distance 

 between its extremity and the mouth being somewhat less than the 

 width of the mouth. Nostrils nearly midway between the extremity 

 of the snout and the mouth. Teeth g?!^' similar inform in both

 distinctly serrated than the lower. GiU-openings wide, at least 

 twiceas wide as the eye, which is small. Pectorals falciform, ex- 

 tending beyond the end of the dorsal, the length of their upper 

 margin being nearly four times that of the lower. First dorsal com- 

 mencing very close behind the axil of the pectoral. Origins of the 

 second dorsal and anal opposite to each other, the bases of both being 

 nearly equally long. Caudal fin long, with the upper edge slightly 

 undulated, its length being equal to the distance between the origins 

 of the two dorsal tins. The lower side of the extremity of the pec-
