PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 491 



tross station 5111 at a depth of 236 fathoms, in the China Sea off 

 southern Luzon. 



Fin-rays — first dorsal, II, 9 ; pectorals, 1G ; ventrals, 7. 



The form and outline of the body are like those of G. platorhyn- 

 chus; greatest depth, about 1.8 in head; greatest width, across 

 pectoral bases, 2.6 ; the greatest width of head is about equal to the 

 depth of head at the vertical through the hind margin of the orbit. 

 ■Preocular length of snout, 2.65 in head ; preoral length, 3.5, less than 

 in G. platorhynchus or C. acantholcpis ; width of snout across base, 

 2.6; width of snout at end of ethmoid portion of infraorbital ridge, 

 three-fourths the length of snout before that point. Length of 

 orbit, 3.7 in head, 1.4 in snout, 1.33 in postorbital; the orbit is thus

somewhat smaller than in the two preceding species. The inter- 

 orbital is markedly wider than in related species; its least width is 

 equal to length of orbit, is contained 1.3 times in postorbital length 

 of head, and contains the least distance between the divergent oc- 

 cipital ridges 2.2 times; least suborbital width, 2.4 in postorbital. 

 The upper jaw is longer and placed farther forward than in 

 C. platorhynchus and C. acantholepis, being contained 3.55 times in 

 length of head, and extending from before nostrils to just behind 

 the pupil; length of barbel, 4.3 in postorbital. A triangular flap, 

 shorter than in C. platorhynchus, extends downward and backward 

 from the lower angle of the subopercle. 



Distance from center of anus to base of outer ventral ray, 2.3 in 

 head; distance between ventral and isthmus, 2.8; distance between 

 anus and isthmus, 1.3. A naked space extends forward a short dis- 

 tance from the anus, as in G. platorhynchus. 



Scales large, in 5^ series between origin of second dorsal and 

 lateral line (exclusive). The scales are not smaller than in C. pi at or-
