PHILIPPINE MACEOUROID FISHES — GILBERT AND HUBBS. 511 



dusky; the outer ventral ray is dark or whitish. The buccal and 

 branchial cavities are wholly lined with bluish black, except along 

 the narrow margin of the opercular and branchi6stegal membranes; 

 the parietal peritoneum is brownish black. 



Although certain rather wide variations are apparent, we have 

 little doubt as to the unity of this species as we now define it.
