Fin-rays—first dorsal, II, 8 (or II, 9); pectoral, 14 ‘(or 15); 
ventral, 6—6 (as also in 6 paratypes, but 6—7 in the onlv other one). 
Pectoral and ventral rays fewer than in C. notatus. 
Greatest depth of body, 1.78 (to 1.72) in head; width over  pec- 
toral bases, 2.30 (2.25 to 2.50), being a little less than the depth 
of the body below the origin of the lateral line. In a smaller speci- 
men, 55 mm. long to anus, the depth is 1.85 and the width 2.64 in 
the head. : 
The dorsal contour of the snout is concave; the snout is broadest 
at its base, its lateral contours converging forward in a curve less 
convex than in C, maculatus and C. velifer, but rather more convex 
than in C. notatus or triocellatus. The tip of the snout is sharp, as 
the terminal plate projects beyond the margin of the following 
scales.
