25; depth of caudal podimclc G; intcrocular width 8; diameter of eye 

 5.5; width at angles of mouth 11 ; distance from tip of snout to end of 

 maxillaiy 9; length of gill slit S; distance frojn tip of snout to disk 

 14; to anus 32.5; diameter of disk 10; distance from disk to anus 7; 

 from anus to front of anal fin 15; distance from tip of snout to front 

 of dorsal 32; longest pectoral ray of upper lobe 17; of lower lobe 17; 

 shortest ray in notch 10. 



Dorsal 37; anal 31 ; pectoral 34. 



Body not deep, compressed. Head rather slender and pointed, 

 compressed; interorbital flat; cheeks not swollen; sides of head 

 nearly vertical. Mouth small, narrow, vrith little lateral cleft; maxil- 

 lary reaching vertical from front of eye. Teeth stout, strongly 

 trilobed, about eight rows in the half of each jaw. Snout rather 

 deep, slightly overlapping the mouth. Posterior nostril with a 

 raised rim, which is produced into a short flap in front; anterior 

 nostril in a long tube, wliich when depressed nearly reaches posterior 

 nostril. Gill opening extending down in front of the upper nine 

 pectoral rays. 



Anterior dorsal rays rather stifl', the first six unsegmented. Caudal 

 truncate, consisting of ten stout rays; dorsal and anal connected to 

 caudal for a short distance, the anal connection a little greater than 

 the dorsal; last rays of dorsal and anal connected to their tips to 

 the caudal. Disk rather small, with a broad flap. Vent close beliind 

 disk, distant from it less than the diameter of the disk. Pectoral 

 notched, the lower lobe of seven rays, its tip reaching vent. 



Coloration: Skin with fine dark brown dots, more numerous on 

 the top of the head, absent from the abdomen; a dark streak running 

 forward and downward from the ej^e; dark spots extenduig back- 

 ward from end of maxillary; pectoral with a broken dark bar near 

 base, the remainder of fin pale; about seven faint duslvy bars on 

 dorsal and anal, the posterior bars extending farther on peduncle; a 

 narrow black bar across base of caudal, a second, less marked, two- 

 tliirds the distance to the tip. In life, the fins and the lower jaw 

 light red, the body grayish. 



Apparently related to C. cyclopus, but not closely so, and easily 

 distinguished by the shape of the head and the number of the fin rays. 



Only the type taken.
