Snout narrow, high, produced, pointed. Body, head, and snout compressed; 

 back hardly elevated above the level of the snout and the tail. Foi'chead con- 

 tinuous into the snout, not decurved. First dorsal subtriangular; spine not 

 reaching the origin of the second dorsal. Second dorsal low, hardly as wide as 

 the orbit, little longer than the snout, as long as the space between the origins 

 of the pectorals and those of the venti'als. Ventrals small, nearly as large as 

 the lirst dorsal. Pectorals large, broad, not reaching the origins of the ventraJs. 

 Sui^racaudal very low, armed on the uj)])ei' edge with sjiines, in a doulile row. 

 Subcaudal much larger, longer, and wider; width al)out that of the orbit. 

 Caudal filament about as long as the snout. No anal fin. I^ateral line nearly 

 straight from the ocular and the orbital sections backward to a point below the 

 origin of the supracaudal; jugular section meeting the orbital a short distance 

 behind the junction of the latter with the suborbital and the angular; prenasal 

 secti(jn not passing up on the side of the snout but continued forward between 

 the nasal and tlie suborbital to the subrostral. See figures in Garman, 1904, 

 Bull. M. C. Z., 41, pi. 2, f. 1 anil 2. Teeth with sharp cutting edges, witliout 

 notches or undulations, (larm., loc. cit., j)!. ."), f. 1 and 2. An adult male is about 

 three feet in length, a female aliout four. 



Sides and below light silvery olive or ])lunibeous I)rown; back, tail and fins

The snout in this genus is elongate, depressed, and somewhat flattened; 

 the forehead curves down in front to the snout ; the teeth have tritors and 

 sinui)us or notched cutting edges; the supracaudal is of moderate height and not 

 armed by spines on its upper edge, and the frontal tenaculum of the male has 

 an elongate much curved stem to comport with the downward curvature of 

 the foreliead.
