PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 451 



Coloration in alcohol. — The body is dark brown, becoming lighter 

 ventrally, but blackish on the belly. A rounded blackish spot, ocel- 

 lated by a whitish ring, extends from the lower end of the pectoral 

 base upward and backward to and including the first row of scales 

 above the lateral line; the spot is nearly as long as the orbit and 

 covers about eight rows of scales (counting downward and back- 

 ward). A less regular and less distinct squarish spot has its four 

 corners at the front of the first dorsal fin, at the origin of the lateral 

 line on each side, and at a point on the top of the head above the pos- 

 terior orbital margin. Another indistinct blotch lies below the 

 posterior end of the first dorsal and the anterior part of the inter- 

 dorsal space. A dark bar, half the head's length behind the spot 

 near the pectoral, covers three scale rows extending downward and 

 backward from the dorsal fin to the lateral line. Behind this region 

 the tail is indistinctly barred. The sides of the abdomen and of the 

 head show silvery reflections. The upper end of the branchiostegal 

 membrane, the opercle, and the posterior border of the preopercle 

 are dull blackish. Elsewhere the head is light, being pale and punc- 

 tate on the under surface, whitish on the mandibular rami, and on 

 the gular and branchiostegal membranes. The buccal and branchial 

 cavities are lined with blackish, except along their light margins. 

 The blackish brown color of the parietal peritoneum, easily rubbed 

 off, is underlain by a bright silvery pigment. The fins are mostly 

 blackish, but are light on the base of the first dorsal, on the entire 

 second dorsal, and on the filament of the outer ventral ray. 



This interesting species has been sufficiently compared with related 

 forms in the preceding analytical key.
