PISCES 179 
Snout short and blunt, its margin obtuse from above, acute 
in profile, shorter than the eye, which latter equals the post 
orbital length: the front edge of the mouth les beneath the 
posterior nostril, but the maxilla reaches to beneath the second 
third of the orbit: the gape is greater than its length; the barbel 
is short, less than half the diameter of the eye; the nostrils are 
as in C. australis, the rostro-infraorbital ridge is well marked 
and slightly sinuous, the nasal ridge is pronounced, terminating 
between the anterior borders of the orbits, the interorbital 
ridges are very faint, and are scarcely traceable beyond the 
hinder margin of the orbits. 
Fins.—The dorsal commences at a point one and a third 
diameters behind the orbit, the first spine is short and the 
second is not quite so long as the second and third rays, which 
are longest and equal to the length of the head less the snout, 
the space between the two fins is small, equal to a third 
that of the base of the first fin; the rays of the second fin are 
very low, and the anterior ones le in a groove: the anal arises 
below the narrow space between the two dorsals, and its middle 
and longest rays are shghtly shorter than the eye: the pectoral 
extends to beneath the fourth ray of the second dorsal, the 
second ray of the ventral reaches the anal, but its first ray is 
a little longer, its hinder insertion is below the first dorsal spine. 
Scales.—The head is everywhere rough- 
ened without distinct scales, the scales on 
the body are comparatively small, and 
those below the dorsal fin bear about 19 
strix, each formed of minute imbricate 
spines, the scales of the lateral line are Scale ot Dean unehas 
aspercephalus. 
split along the middle. x 4, 
Colours—The general colour is greyish-yellow with many 
darker grey cross bands, which incline forward below; the 
edges of the opercles and branchiostegals and many of the scales 
bear minute black dots: the distal half of the first dorsal fin and 
all the ventral rays, the tip of the first excepted, are clouded, 
the tint in the ventrals being deepened by the presence of black 
dots: a black band runs along the whole length of the anal fin 
midway between the tips and bases of the rays. 
Length.—264 mm. 
This species may be distinguished from C. australis by its 
short, obtuse snout, the absence of definite scales on the head, 
the short intradorsal space, the smaller and smoother scales, 
the different direction of the dark bands crossing the body, 
and the character of the anal band: the scaleless head also
