PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 443 
is obtusely pointed. The orbit is conspicuously larger than in C. 
argentatus or C’. quincunciatus; its length is contained 3.9 (3.85 
to 4.15) times in the head, 1.8 (1.8 to 1.95) times in the snout, 
1.15 (1.05 to 1.2) times in the postorbital. The least interorbital 
width is greater than in the other species of the subgenus, it is a 
little less than the orbital length, and is contained 1.3 (1.23 to 1.4) 
times in the postorbital. The suborbital also averages wider, being 
contained 2.6 (2.5 to 3.0) times in the postorbital. The short upper 
jaw extends backward from below the posterior nostril not so far 
as the vertical from hind margin of the orbit; its length is contained 
4.05 (4.2 to 4.35) times in the head. The barbel is short, being 
contained 4.4 (8.4 to 4.6) times in the postorbital. The cardiform 
teeth of the premaxillary are in a narrow band; those of the lower

jaw, in two irregular series on the sides posteriorly, become so 
crowded near the symphysis as to form a narrow band. 
The anus is located immediately in advance of the origin of the 
anal fin, somewhat farther forward than in C. quincunciatus, and 
much farther forward than in argentatus,; it lies below the posterior 
half of the interdorsal space; the distance from the center of the 
anus to the base of the outer ventral ray is contained 2.7 (2.9 to 3.5) 
times in the head; the distance between the ventral fin and the 
isthmus (at the front of the scaled area), 1s contained 3.3 (3.6 to 3.85) 
times in the head; the total distance, from the anus to the isthmus, 
1.6 (1.65 to 2.0) times. As in argentatus and quincunciatus, the 
anterior lobe of the gland-like body in the abdominal wall is sup- 
ported by a slender rod connected with the joined ends of the two 
pairs of-arms of the pubic bones. 
Pyloric caeca—14 in 2 specimens (stations 5110 and 5118) ; 22 in 2 
specimens (station 5518); 9 were counted in a specimen of argen- 
tatus, and 8 to 11 were counted in 4 specimens of guincunciatus.
