1 B. furvescens was also dredged at this station. 
The body is deep and sharply compressed, thin posteriorly; the 
width of the body across the pectoral bases is two-fifths its greatest 
depth. The head is broad and cavernous; its membrane-bones are 
thin and papery. The dorsal contour is arched behind the occi- 
put, but concave from the occiput forward to the tip of the pre- 
maxillary spine, which enters conspicuously into the profile; the ven- 
tral contour is angulated more sharply than usual at the posterior 
end of the mandible. The sides of the head are subvertical. The 
orbit is rather small, its length being contained five times in the 
head, or 1.8 (1.7 to 1.8 in paratypes) times in the least interorbital 
width, which is as great as, or slightly greater than, the length of 
the snout, and is contained slightly more than three times in the 
head. The least width of the suborbital space is contained 1.3 (1.3 
to 1.5) times in the length of the orbit. The opercle, as usual, di- 
vides posteriorly into two branches, the upper of which ends in a 
flat and weak spine; the lower branch, also weak, extends across the 
subopercle to an acute tip. The lower margin of the interopercle is 
arched upward more strongly than in the related Japanese species, 
B. antrodes. The posterior angle of the interopercle is produced 
backward in the form of an acutely rounded lobe, which is longer 
and narrower than that of B. antrodes; the tip of this flap is visible 
behind the rounded angle of the preopercle. 
The mouth is oblique and large; the upper jaw extends to the ver- 
tical from the hind margin of the orbit, and is contained 1.8 (to 
1.9) times in the head. The teeth are rather coarse and irregularly 
placed in the premaxillary band, which is margined within by a defi- 
nite, narrow, parrallel-sided area of shagreen-like teeth, extending
