PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 453 
body below the lateral line (only half the depth in very small speci- 
mens). In trimness of form, and in firmness of texture, this species 
presents an appearance intermediate between C. maculatus and C. 
notatus, confirming other intermediate characters, such as the spinu- 
lation of the scales and the color. As further evidence of its inter- 
mediate position, this species in certain of its characters most clearly 
resembles each of the other two. 
The dorsal contour of the snout, as in C. maculatus and C. ma- 
crolepis, is straight, and the outline behind the snout is nearly 
straight; the ventral contour is evenly and slightly curved down- 
ward behind the mouth. The short, broad, deep, snout, with its 
widely convex sides, closely resembles that of C. platorhynchus, C. 
acantholepis, and C. carinifer, which are species of another sub- 
genus. The tip of the snout is blunt, the dorsoterminal plate being 
little or not at all produced beyond the line of the following scales 
on the infraorbitai ridge; the depth and width of the snout through 
the terminal plates are about equal.

1The number of specimens on which the given average was based. 
The preceding table of measurements clearly shows certain vari- 
ations of the relative proportions which are correlated with the size 
of the individual: the orbit becomes smaller in larger specimens, the 
interorbital narrower, the maxillary longer, and the snout shorter. 
A comparison of these measurements with those of C. maculatus 
shows three of the differences which distinguish the two species; the 
snout is shorter in (. velifer, the interorbital narrower, and the 
mouth larger. 
The posteroventral angle of the subopercle is produced backward 
and downward into a pointed flap. The orbit is of rounded-oblong 
outline. The interorbital space is narrowest above the front margin 
of the pupil, behind which point the slightly convex sides rapidly 
diverge; the least width of the suborbital is less than in C. macu- 
latus, being contained 2.5 (2.3 to 2.7) times in the postorbital length
