Spec. Char.^A very slender and elegant species, differing from C. vigilax by a more conical head, much larger eyes, and 

 larger scales. The latter are much deeper than long, with radiating furrows upon the posterior section alone. A black spot 

 may be observed upon the anterior margin of the dorsal fin. 



Syn. — Cliola velo'x, Grd. in Proc. Acad. Nat. Sc. Philad VIII, 185G, 192. 



The ground color is olivaceous, with the middle of the flanks silvery ; a black streak follows 

 the course of the lateral line. A black spot exists also upon the base of the caudal fin.

 region ; fig. 23^ a scale from the lateral line ; and, fig. 24, a scale from the abdominal region.
