PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 461 
Coloration in alcohol.—The ground color is lighter than in (@. nota- 
‘tus, velifer, or maculatus; the belly is dark, becoming blackish be- 
tween the ventral fins. An ocellated blackish spot extends upward 
and backward from the pectoral onto the first row of scales above 
the lateral line, covering 6 (5 to 7) rows of scales extending down- 
ward and backward. There is a dusky blotch between the first 
dorsal fin and the occiput, and only faint traces of a dusky saddle 
representing the well-defined marking in C. notatus. The dark lining 
of the buccal cavity becomes light near the gape; the light margin 
along the outer edge of the branchiostegal membranes widens ven- 
trally; the parietal peritoneum is pale purplish brown, punctulate, 
and underlain with silvery. The whitish proximal color of the first 
dorsal shades into black distally. The second dorsal and the anal 
fins are light, the anal becoming uniformly dark anteriorly. The 
ventral fin is dark except on the distal and larger portion of its first 
ray; the pectoral fin, otherwise light, is darkened on its uppermost 
two rays. ; 
C. sexradiatus differs from the nearest relative, C. notatus, in 
many points: the fewer rays in the paired fins; the more convex mar- 
gins of the snout; the longer and more prominent dorsoterminal 
plate; the more posterior position of the anus; the longer ventral 
fossa; the somewhat smoother carinae on the scales; many details, as 
outlined heretofore, in the squamation of the head; the lighter color, 
with but traces of the dark saddles so characteristic of notatus.
