1 About. 
In the following description comparison is made with C. plato- 
rhynchus ; certain details alike in the two species are omitted. After 
the various measurements and counts of the type, two additional 
measurements or counts, if different, are given in parentheses: first, 
of the paratype 113 mm. long to anus; second, of the specimen 59 
mm. long to anus; the smallest one, being in poor condition, is not 
‘included in the description. 
Fin-rays—first dorsal, II, 9; pectorals, 17 (18, 18); ventrals, 7. 
The form of the head as seen from above is well figured by Rad- 
cliffe (see fig. 17). The depth of the body, 1.8 (1.9, 2.4) in head, is 
slightly greater below the origin of the first dorsal fin than at any 
other vertical; greatest width of body, 2.4 (2.3, 2.75). Measurements 
of snout into head—preocular length, 2.6 (2.55, 2.4) ; preoral length, 
3.05 (2.9, 2.85); width across base of snout, 2.6 (2.6, 2.5); width 
across snout, at end of ethmoid portion of infraorbital ridge, 0.8 
(0.8, 0.85) in length of snout before that point. Least distance be- 
tween divergent occipital ridges, 1.8 (1.6, 1.85) in interorbital. 
Length of orbit—into head, 3.4 (3.6, 3.4) ; into snout, 1.33 (1.35, 1.35) ; 
inte; postorbital., lbs, AOS). Least interorbital width, 1.5 
(1. 6, 1.4); least suborbital width, 9.8 (2.25, 2.2). Length of upper 
jaw, 3.9 (3.9, 4.0); the upper jaw ocienae from below the anterior 
nostril to behind the pupil. Length of barbel, 4.8 in postorbital 
(in largest paratype). 
Distance from center of anus to base of outer ventral ray, 2.65 
(2.8, 2.7) into head; distance between ventral and isthmus, 3.05 
(3.4, 3.4) ; distance ae anus to isthmus, 1.5 (1.7, 1.6).
