119. C. bisoBi Agassiz. 
Head long, contained about 3i times in length to base of caudal. 
Muzzle elongate-conic, so that the eye is nearly median, the middle of 
the length of the head falling in front of its posterior margin. Body not 
much arched, depth 3 in length. Anterior rays of dorsal pretty high, 
not much shorter than the base of the fin, not thickened at base. Lips 
well developed. Eye large, 4i in head. Scales 7-40-5 ; D. 27 ; A. 7 ;

IMuzzle conic, projecting, obtusely pointed, tip of the mandible reach- 
ing to opposite nostrils ; maxillary reaching to opposite front of orbit. 
Anterior suborbital as deep as long. Head 3^-4 in length. Eye large, 
ill length of head. Body much arched above, the depth 24-21

* The original C’atostonufs cyprimis was described from tributaries of Chesapeake 
Bay. It cannot be the present species, as the dorsal is described and tigured as 
strongly lalcate and ithe caudal deeply forked. We have seen no specimens from the 
original locality. 
t Possibly two or three species are here included: velifer, with the anterior dorsal 
rays longer than the fin ; ci/priwas, with them somewhat shorter; and cutisanscrimts, 
■with a blunter snout and the dorsal rays ver5^ long.
