PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. . 385 
tained 1.5 times in the least interorbital width, which is contained 
three times in the head. 
The lower margin of the interopercle is but slightly concave. 
The flap at its posteroventral angle is short and blunt, only its tip 
being visible behind the semicircular margin of the preopercle. 
The inner shagreen-like portion of the premaxillary band of teeth 
extends only along the posterior half of the band. The teeth in 
the narrow mandibular band are of unequal size. 
Seven branchiostegal rays. The small pseudobranchial filaments 
are concealed beneath the skin. 
A single main series of oval, imbricate scales extends along each 
mandibular ramus, but this series is flanked along its outer side by 
a few small scales. The lateral line on the tail runs below the middle 
of the depth, as in other species. 
The pyloric caeca, 30 in number, are about two-thirds as long as 
the orbit. 
Lining of the buccal, brinchint ‘and abdominal cavities wholly 
black. 
— B. filamentosus is perhaps most closely related to B. antrodes of 
Japan, differing from that species, however, in the narrower, firmer 
head, larger eye, longer fin filaments, more numerous pyloric caeca, 
ete. It is probably related also to B. micronema, an Hawaiian species, 
but differs, in addition to the characteristics mentioned by Radcliffe, 
in the fewer gill-rakers.
