PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 493 



whitish. The fins are all dusky. The buccal cavity is lined with 

 bluish black, becoming decidedly lighter hear mouth; branchial 

 cavity lined with brownish black, except on a narrow but abrupt 

 whitish margin along the opercular and branchiostegal membranes; 

 the peritoneum is dusky-purplish, underlain by silvery. 



The lighter color and firmer flesh of this species are characters cor- 

 related with the lesser depth probably inhabited by it (as compared 

 with C. platorhynchus and C. acantholepis) . Other distinguishing 

 characters are given in the key to the species.
