. The scales are in 44 rows between the origin of the second dorsal 
and the lateral line series; an additional series is inserted shortly 
behind that point (the first rays of the second dorsal are broken 
off in the type). The spinules on the body scales are set along 4 to 
7 carinae’; these spinules are similar to those of C. platorhynchus, 
being strong, but somewhat weaker than in that species. The scales 
on the front half of the infraorbital ridge often have about three 
series of spinules directed upward and backward; there are 8 scales 
on each side of the ethmoid region of the infraorbital ridge, and 9 
(8, 8) on the preorbital region, which is bounded above by a smaller 
but similar series subtending the front half of the orbit; the sub- 
orbital and preopercular portions of the ridge are covered by two 
series of similar scales; the distance between the end of the in- 
fraorbital ridge and the preopercular margin is contained 4.6 (4.6, 4.0)

times in the postorbital. The median rostral ridge is covered by 11 
(10, 9) subquadrate scales with 5 to 7 carinae radiating from near 
the front margin of the scale. The scales of the occipital and 
postorbital series, like those of C. platorhynchus, bear but a single 
keel. The occipital scute has only a median spinous keel; it is pre- 
ceded in the two larger specimens by a short naked area, but in the 
smaller paratype by two similar scutes, one on either side. The 
scales along the supraorbital ridge are-armed by numerous close-set 
spinules. The other scales on top of head are arranged as in C. 
platorhynchus, but are armed with 1 to 7 (usually several) carinae. 
The scales in the region between the occipital and the infraorbital 
ridges are in general similar to those on the body, but rather smaller ; 
a median series between the occipital and postorbital ridges is en- 
larged; the scales on the lower half of the cheeks, downward and 
backward from the eye, and those between the preopercular and in- 
traorbital ridges, are reduced in size and are usually armed only 
by a single keel. The anterolateral region of the snout, the nasal
