PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 447 
The slender body is not strongly compressed, the width being 
equal to the depth below the origin of the lateral line; the greatest 
depth is contained 1.8 (to 1.95) times in the head. The dorsal con- 
tour of the snout in this species is straight, and is more oblique 
than the postrostral outline, which is nearly straight; the ventral 
contour is gently convex behind the mouth. The snout is broad and 
deep, with sides evenly and strongly convex to the bluntish tip, 
which is not produced in the type, and but little produced in the

This table seems to indicate that the relative length of the snout 
decreases with increased size, as it does also in C. jordani and in other 
species of this subgenus, while the reverse condition obtains in cer- 
tain species of the subgenera Oxymacrurus and Ouygadus.. The 
middle of the length of the head in the largest specimen, the type, 
is at the center of the pupil, while it is at the front margin of the 
pupil in the smallest specimen, in which the head is 35.5 mm. long. 
The scaly ridges of the head are strongly developed, the occipital

subgenus Oxvygadus.
