PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 487 



strong spinules ; the median occipital scute is also a strong tubercle, 

 bearing a single spinous keel (three in one specimen) ; the scute may 

 or may not be preceded on each side by a similar scale, or by a short 

 naked region; from near the front of the scute five rows of scales 

 diverge forward, confined posteriorly between the occipital ridges, 

 but curving outward on the snout to bound the median series ; these 

 scales are mostly armed by a single, but sometimes by 2, 3, or even 4 

 trenchant spinuous keels. The anterolateral region of the snout, 

 within the infraorbital ridge, together with the lower portion of 

 the nasal fossa, is covered by small scales with a single (more rarely 

 several) spinous ridge, the height of which may exceed the length 

 of the scale. The series of scales on the postorbital and the posterior 

 half of the supraorbital ridges are similar to those of the occipital 

 ridges; between the postorbital and occipital ridges the scales are 

 little modified, usually bearing several carinae; those bounding the 

 ridges are reduced in size, while those forming the median series 

 are somewhat enlarged. The scales on the opercles and on the 

 upper half of the cheeks in general are similar to those of the body. 

 The underside of the head, excluding only the lips and the gular 

 and branchiostegal membranes, is wholly covered by small scales, 

 each of which bears a high spiny keel. 



In one paratype the outer ventral ray, reaching a little past the 

 origin of the anal, is 0.53 of the length of the head (0.45 in type). 

 Length of the pectoral fin, 2.0 to 2.4 in head. 



The color becomes darker on the belly and opercles. The linings 

 of the buccal, branchial, and peritoneal cavities are wholly dark 

 brown, with the exception of an indistinct light margin along the 

 free edge of the opercular and branchiostegal membranes.
