PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 465' 



of the head. The second dorsal is lower anteriorly than in C . macu- 

 Jatus or velifer, its first ray being contained 7.5 times in the orbit. 

 The anal fin originates in advance of the second dorsal a distance 

 one-third as great as the interval between the dorsals. The pectoral 

 fin is short; the outer ventral ray is contained 1.95 times in the head; 

 the second ray, 3.15 times. 



Coloration in alcohol. — Ground color, light brown, with silvery 

 reflections on the sides of the head and trunk; the color is lighter 

 than in maculatus or velifer. The belly is blackish 'only in advance 

 of the ventrals (no such restriction of the black area occurs in macu- 

 latus, velifer, nor triocellatus) . A large blackish brown imperfectly 

 ocellated spot, extending from the pectoral fin to the lateral line,, 

 covers six scale rows counting downward and backward; it is thus 

 smaller than in C. maculatus or O. velifer. A dark area, not well 

 defined, extends from the first dorsal fin to the occiput; a dark spot, 

 of irregular outline (too sharply emphasized in the type figure), 

 is located before the origin of the lateral line. An ocellated saddle 

 of dark brown color, covering six scale rows, extends across the 

 back downward to the lateral line ; it is separated from the pectoral 

 spot by a distance enterring twice into the head ; a saddle of similar 

 width, but not ocellated, is separated from the anterior saddle by a 

 distance contained 1.75 times in the head; the tail is indistinctly 

 barred behind these saddles. The opercles are dusky, becoming 

 blackish toward the opercular angle. The buccal cavity is lined 

 with light around the mouth and with dark dusky blue within; the 

 branchial cavity is lined with purplish black except along the light 

 margin of the outer wall; the abdominal cavity is lined with pale 

 purplish brown, punctulate with darker, and underlain by silvery 

 pigment. " Basal sixth of second dorsal spine light brownish yel- 

 low, distal portion dusky black, the dark markings of the spine ex- 

 tending onto distal portion of soft rays; second dorsal light; basal 

 portion of anal light, distal portion of fin anteriorly almost black; 

 ventrals dusky black, filament of outer ray whitish; pectoral dusky 

 white," its uppermost two rays dark.

 of head, 75 ; length of orbit, 22 ; postorbital length of head, 25 ; least 

 width of interorbital, 15 ; least suborbital width, 10.5 ; distance from 

 orbit to preopercle, 28 ; length of snout, 28 ; width of snout, 29 ; length 

 of upper jaw, 20; length of barbel, 7; depth of body, 46.5; width 

 of body across pectorals, 31.5 ; distance from center of anus to origin 

 of anal, 15; distance from anus to base of outer ventral ray, 20.5; 

 distance between ventral and isthmus, 23; length of first dorsal 

 base, 18 ; interdorsal space, 22.5 ; length of outer ventral ray, 40.
