Width of head at base of humeral process or coracoids 35.4 (35.6); 

 leng-th of head from tip of snout to posterior end of supraoccipital 

 plate 36.0 (33.6) : length of head from snout to rear of temporal plate 

 37.9 (34.6); tip of snout to upper edge of gill opening 29.2 (28.4); 

 greatest depth of body 20.5 (21.3); length of snout 24.9 (24.3); width 

 of fleshy interorbital space 12.5 (12.4); diameter of eye 5.12 (4.55); 

 length from base of last anal ray to midbase of caudal fin rays 26.3 

 (29.0): least depth of caudal peduncle 14.7 (14.6); length of ramus of 

 lower jaw 12.0 (12.5) ; greatest width of lower lip 6.49 (6.55) ; rear edge 

 of eye to posterior edge of temporal plate opposite first lateral line 

 pore 8.88 (10.5); length of first ray of dorsal fm 28.5 (29.1); length of 

 last ray of dorsal 16.6 (17.4); length of pectoral spine 30.9 (35.4); 



length of upper ray of caudal fin 35.0 ( ); length of lower ray of 



caudal fin 40.3 ( ); length of ray of adipose fin 11.1 (10.8) ; length 



of longest anal fin ray 12.0 (12.8); length of base of dorsal fin 27.5 

 (25.6); distance from bony edge of nasal opening to tip of snout 17.0 

 (18.6); distance from edge of nasal opening to eye 5.12 (5.98); tip of 

 snout to origin of dorsal fin 48.1 (44.3); tip of snout to origin of anal 

 fin 70.3 (69.5); tip of snout to origin of adipose 83.7 (84.0); distance 

 from anus to anal origin 8.20 (9.30). 



The following counts were made: Dorsal rays 1,8 (1,8), anal 1,5 

 (1,5); pelvic 1,5 (1,5); pectoral 1,6 (1,6); series of lateral scutes 24 

 (24) ; pores in lateral line 25 (25) ; interopercle with 4 (5) hooked spines; 

 about 6 (8) spines on operculum.; 11 (12) scutes between anal and base 

 of caudal; 5 (5) scutes between dorsal and adipose and 4 (4) in front 

 of dorsal. 



The body is short and its width broad as in C. anomala; the width 

 at coracoids is equal to the distance from tip of snout to rear of 

 supraoccipital plate and is contained 2.9 tunes in the standard length; 

 a small dermal keel, a little longer than pupil, lies along middorsal 

 line at rear tip of the supraoccipital plate; interorbital space about 

 \%o in the snout; eye 2^ in interorbital space and 4%o in the snout; 

 length of depressed anal a little longer than the width of interorbital 

 space; plates all prickly; dorsal spine not much larger than the soft 

 rays; pectoral spine enlarged with strong spines; soft rays of pelvics 

 and pectorals with prickles; anterior third of snout fleshy, without 

 plates, but with small folds; lips papiflate; belly naked; a barbel at 

 each corner of the mouth ; a narrow naked area along base of dorsal, 

 but along base of adipose the naked area is obsolete; intestines much 

 coiled; peritoneum blackish; caudal fin deeply concave, tlie upper 

 lobe equal to distance from snout to rear of supraoccipital. 



Color. — Grayish brown above paler below; top of head and sides 

 with small dark spots caudal plain grayish, as in many specimens of 

 C. anomala anomala and C. anomala sovichthys, but the forked caudal
