jaws ; minute deciduous teeth on the vomer, the palatines, and on 

 the tongue ; sometimes entirely absent. The height of the body is 

 2|-3 times in the total length, the length of the head five times. 

 Breast scaly; the curve of the lateral line is semicircular, and becomes 

 abruptly straight below the fourth dorsal ray ; the plates are weU 

 developed, and occupy the whole of the straight portion of the line. 

 The jaws are equal anteriorly, and the upper maxillary reaches 

 somewhat beyond the vertical from the anterior margin of the eye. 

 The upper caudal lobe much longer than the lower. Opercular spot 

 none ; base of the pectoral deep black.

The teeth are minute, and form a single series in both the jaws ; 

 palate toothless. The height of the body is 2| in the total length, 

 the length of the head 4|^. Breast scaly ; the curve of the lateral 

 line is semicircular, and becomes abruptly straight below the first 

 dorsal ray; the plates are well developed, and occupy the whole 

 of the straight portion of the line. The lower jaw is slightly longer 

 than the upper, and the maxillary reaches to the vertical from the 

 anterior margin of the eye. Caudal lobes equal in length. A black 

 opercular spot ; dorsal, anal, and ventral black ; caudal, pectoral, and 

 base of the pectoral yellowish ; body with five blackish cross-baiidi

Description. — The specimens are apparently immature, showing, 

 however, sufficient characters by which the species may bo readily 

 distingiiished from C. amblyrJiynchus. The body is compressed, 

 elliptical, with the upper and lower profiles equally curv'ed; its 

 greatest depth is between the origin of the soft dorsal and anal fins, 

 where it is contained 2| in the total length. The head is of moderate 

 size, as high as long, with the upper side strongly convex. The snout 

 is rather short, a little longer than the diameter of the eye, with the 

 cleft of the mouth oblique, and with the lower jaw slightly promi- 

 nent ; the maxillary extends to the vertical from the anterior mar- 

 gin of the eye. The teeth in the jaws are minute, forming a single 

 series ; the palate is smooth, but the tongue appears to be provided 

 with some asperities. The nostrils stand nearer to the superior 

 angle of the orbit than to the extremity of the snout. The eye is 

 situated nearer to the upper profile of the head than to the lower. 

 The prajoperculum has the margin entire, and the lower limb much 

 shorter than the posterior ; both meet at a rather obtuse angle, 

 which, however, is rounded.
