PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 501 
The anus is located immediately before the origin of the anal fin; 
its distance from the base of the outer ventral ray is less than the 
distance between the ventral fin and the isthmus, and is equal to, 
or less than, the length of the orbit, being contained 3.7 (3.4 to 4.65) 
times in the length of the head; distance between ventral fin and 
isthmus, 3.1 (2.7 to 4.0); distance between anus and isthmus, 1.85

(1.65 to 2.4). As in the foregoing species of the subgenus Ovyma- 
crurus, the anus is preceded by a short naked area, which lies just 
below the gland-like organ in the body wall. 
Pyloric caeca, 39 (in one paratype), shorter than the orbit. 
Scales large, in but 44 (or 4) rows from the origin of the second 
dorsal fin to but excluding the lateral line series. The numerous 
carinae, bearing many comparatively weak spinules, are highly diag- 
nostic of the species. There are from 6 to 11 carinae on the scales

-of specimens more than 95 mm. long to anus, and from 5 to 8 in 
smaller specimens. The short and slender spinules lack the promi- 
nent ridges and concave surfaces as described for C. smithi, the 
spinules, furthermore, are more numerous than in that species, there 
being about 8 on each carina, as many as 6 in the specimen only 
46.5 mm. long to the anus (7 is the largest number of spinules in 
any series in the adult of C. smithi). The terminal rostral plates 
are each armed by about four long rows of spinules, which become
