termination of these series of scales and the occipital scute there is an 
area covered by prickles anteriorly but naked posteriorly. The oc- 
cipital scute, often double or even triple,’ is armed by a strong 
median spinous keel and by a few weaker lateral carinae variously 
developed; no scute is present on the mid-dorsal line between the 
occipital scute and the dorsal fin, but there is a small scute just 
above the origin of the lateral line. The median of the 3 irregular 
series of scales between the occipital and postorbital ridges is en- 
larged only anteriorly. Except for the presence of a few scales 
posteriorly, the anterolateral region of the snout is wholly naked. 
There are no scales on the under side of the head. 
The first dorsal spine is stout and very short; the second spine 
is about as long as the first soft ray, and when unbroken at its tip

is about equal to the postrostral length of the head (often somewhat 
longer, sometimes slightly shorter). The base of the first dorsal is 
contained 1.6 (1.25 to 1.6) times in the interdorsal space, and 1.5 
(1.3 to 1.6) times in the postorbital. The origin of the anal lies 
behind the vertical from the middle of the interdorsal space. Length 
of pectoral, 2.15 (to 2.8) in the head. As in the case of C. argus, 
this wide variation in the length of the fin-rays appears not to be 
correlated with sex. The outer ventral ray is constantly shorter 
than in related species except argus, being contained 2.4 times in the 
head in the type and in most of the paratypes of either sex, but vary- 
ing from 2.25 to 2.6. The short second ventral ray fails to reach the 
anal, and is contained 3.9 to 4.4 times in the head.
