1B. spongiceps was also dredged at this station. 2 About 700. 
In the form and the texture of the head this species occupies a 
position intermediate between B. entomelas and B. filamentosus. 
The body is compressed more strongly than in B. entomelas, but less 
strongly than in B. filamentosus, the width across the pectoral bases 
being contained about 24 times in the greatest depth of the body. 
The length of the orbit is contained from 4.5 to 5.0 * times in the head ; 
2.2 to 2.6 times in the length of the head behind the orbit; 1.2 to 1.35 
times in the snout; and 1.2 times in the interorbital width. The 
length of the snout and the least interorbital width are each contained 
from 3.6 to 3.8 times in the head. The least suborbital width enters 
2.2 to 2.3 times into the interorbital. The opercle ends posteriorly in 
two weak spines, only the tips of which are exposed. The form of 
the interopercle is lke that of B. entomelas, its posterior flap is just 
visible behind the preopercle. Length of upper jaw, 1.8. The teeth 
are finer than usual in Bathygadus, the premaxillary band is 0.2 as 
wide as the orbit; its inner shagreen-like portion is narrow and not 
strongly differentiated from the outer portion; the villiform teeth of 
the mandible form a band nearly half as wide as the premaxillary 
band (the dentition is quite different in B. entomelas). The barbel 
is absent. Pseudobranchial filaments are constantly present; the slit 
behind the fourth gill-arch is shorter than the orbit. The scapular 
foramen pierces the hypercoracoid about its own diameter above the 
suture between that bone and the hypocoracoid (determined in three 
specimens; both sides examined in one). 
Seven series of thin and deciduous scales occupy the space between 
the origin of the second dorsal and the lateral line series. There are 
two series on thé mandible, but none on the face of the shoulder 
girdle beneath the opercles. 
None of the fins are greatly produced or strengthened. The 
ventral fin is inserted but little before the base of the pectoral or the 
origin of the dorsal. 
Twenty pyloric caeca, two-thirds as long as the orbit, were counted 
In One specimen. 
The coloration is darker than in B. entomelas. The fins are black- 
ish; the buccal, branchial, and abdominal cavities are wholly lined 
1In the largest specimen.
