The total length of the type is 80 mm. ; to the base of the 

 caudal fin, 55 mm. The body is deeper than it is in C. vexil- 

 lifer (Pictet), the greatest depth, 30 mm., being contained in 

 the length to the base of the caudal somewhat less than two 

 times ; and in the distance from the pectoral arch to the base 

 of the caudal, one and one fourth times. The length of the 

 head, 21 mm., is less than the greatest depth of the body. 



The height of the dorsal fin is fully 30 mm., and when de- 

 pressed its distal end would reach beyond the base of the 

 caudal fin. It contains 20 rays, including the anterior un- 

 divided ones. The anal fin has a height of 13 mm., but the 

 rays are broken and zigzagged, so that it is evident that 

 originally the fin was still higher. There are present in it 

 13 or 14 rays. 



The body is slightly turned, so that both ventral fins come 

 into view. These sweep backward along the lower border of 

 the body and cross all the anal fin-rays. The pectoral fins 

 are only dimly seen. 



The maxilla is provided with short conical teeth. This 

 bone and the supramaxilla resemble those of C. radians, as 

 figured by Dr. A. S. Woodward (Cat. Foss. Fishes, IV, pi. x, 

 figs. 2,3). The cheeks and the opercular bones are covered 

 with scales. 



No. 45216 (3813) shows only the posterior half of the body. 

 The dorsal fin is depressed and overlaps the base of the caudal 

 fin. The anal rays pass somewhat behind the last caudal 

 vertebra. Some of the rays of the ventrals extend beyond 

 the origin of the anal. 



This species differs from C. vexilUfer in having a shorter 

 and deeper body, much higher dorsal and anal fins, and lon- 

 ger ventral fins. 



No. 4522 (3802) is a small fish from Hakel which I identify 

 as C. vexilUfer. The length to the base of the caudal is 35 

 mm. and the depth is 14 mm. The fish is therefore consider- 

 ably slenderer than the specimens of C. signijer. The pecto- 

 ral fin in this Hakel specimen also is long, as in those from 

 Hajula; but the dorsal is not more elevated than usual.
