The body is elongated and fusiform, the greatest depth taken at the anterior third of the body 

 being contained four times and a half in the total length, of v/hich the head forms somewhat 

 less than the fourth. The head, therefore, is well developed ; the eye is circular, its diameter 

 being contained four times in the length of the side of the head. 



The dorsal fin is much higher, and the anal somewhat deeper, than long ; the origin of the 

 anal being equidistant between the isthmus and the fork of the caudal. The ventrals are poste- 

 riorly rounded, their extremities overlapping the vent without reaching the origin of the anal.

The scales are larger than in any of its hitherto known congeners ; they are less attenuated 

 superiorly and inferiorly than in C. mnbrosa. 



The color is reddish ash above and pale sulphur yellow beneath, the sides exhibiting a 

 metallic tint, sometimes whitish, at others yellowish. The dorsal and caudal are greyish 

 yellow ; the rest of the fins pale yellow.

 Plate LVIII, Figs. 16—20. 



Spec. Char. — Body elongated, sub-fusiform. Peduncle of the tail rather slender. Head constituting the fifth of the total 

 length. Eye moderate sized ; its diameter entering about three times and a half in the length of the side of the head. Snout 

 anteriorly blunt ; gape of mouth slightly arched ; posterior extremity of ma.xiUar bone reaching to a vertical line drawn behind 

 the nostrils. Anterior margin of dorsal fin somewhat nearer the insertion of the caudal than the tip of the snout. Origin of 

 ventrals placed in advance of the anterior margin of the dorsal. Pectorals small. Reddish brown above; yellowish beneath ; 

 a jet black spot at the base of the caudal ; fins otherwise unicolor.

Here is another elongated and fusiform species, but which may easily be distinguished from 

 C lepida by a shorter head, a less furcated caudal, and especially by the presence of smaller 

 scales. The dorsal is much higher and the anal somewhat deeper than long ; the anterior 

 margin of the anal being equidistant between the fork of the caudal and the extremity of the 

 snout. The ventrals are of moderate development, posteriorly sub-truncated, their tips reaching 

 the vent. The pectorals are small and far from extending to the origin of the ventrals.

The scales, besides being smaller than in C. lepida, are less tapering still at their superior 

 and inferior edges ; the radiating furrows being also more numerous. 



The dorsal region is reddish brown, and the abdominal yellowish with a metallic reflect, 

 assuming rather an argentine tint along the middle of the flanks. A jet black patch may be 

 observed at the base of the caudal, which is greyish olive, like the dorsal ; the rest of the fins 

 being yellowish.
