PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 499 
Type-specimen.—Cat. No. 78224, U.S.N.M., 268 mm. in total 
length; 101 mm. to anus; from Albatross station 5503. 
The form called gamma was apparently distinguished from beta 
by its shorter, blunter snout. In the three specimens of gamma 
other than the type this difference is to be accounted for chiefly by 
the fact that the terminal spine has been broken off. We are not 
sure that the tip of the snout is broken in the type of gamma, which 
is the largest specimen known; it may be that the snout becomes 
blunter in very old individuals, or perhaps the spine in that speci- 
men had been broken off and had since healed over. The measure- 
ments are taken on this specimen with the assumption that the tip 
has not been broken off, and when different from others are given 
separately. 
The following description is based upon all of the specimens 
which vary in length to anus from 46.5 to 134.5 mm.; those charac- 
ters which vary with age are so noted. 
Fin-rays—first dorsal, II, 8 (rarely 7, sometimes 9); pectorals, 
17 (15 to 18) ; ventrals, 7. 
This species resembles C. smithi in its arched contours; the snout 
is shghtly concave along its dorsal margin; the base of the first 
dorsal fin is oblique; the greatest depth of the body lies below the 
origin of the first dorsal fin, and is contained 2.0 (1.9 to 2.3; 2.6 in 
young) times in the length of head; the greatest width across the 
pectoral bases, 2.7 times (2.5 to 2.7; much narrower in young, 4.0). 
The snout is much longer in the young than in very large speci- 
mens, as indicated in the figures and in the following:

The form of the snout as seen from above is indicated by text fig- 
ures 23 and 24. The same figures also show the courses of the strong 
spinous ridges of the head; the least distance between the occipital 
ridges, which diverge a little in both directions, is contained 1.95 
times (to 2.1, 1.8 times in specimen 46.5 mm. long to anus) in the 
postorbital length of the head. The subopercular flap is rather oh- 
tusely pointed; its lower margin is nearly horizontal. The orbit is
