Bathygadus favosus, n. sp. 
The type is a specimen, 350 millimeters in length, obtained by the “ Blake” 
at Station Lxxx., off Martinique, at a depth of 472 fathoms, with the Fish 
Commission specimens catalogued below as collateral types. 
The body is heavy, stout ; its greatest height, at origin of first dorsal (57 mm.), 
is contained a little more than six times in the total length. The profile of 
the body descends gradually and in a slight curve from the first dorsal to the 
snout. 
The scales are small, deciduous, cycloid, without armature, about 135 in the 
lateral line, about 10 above and 16 below the lateral line, the latter series 
counted from the vent. 
The length of the head (65 mm.) is contained about 5} times in total length. 
The interorbital area is slightly convex ; its greatest width (22 mm.) equals 
about 4 of the length of the head. The postorbital part of the head is 22 times 
as long as the eye, which is nearly round, its diameter equal to 4 the length of 
the head. The snout is broad, oblique, its width at the nostrils (23 mm.) a 
little more than the width of interorbital area; its length (17 mm.) slightly 
more than } that of the head. The nostrils are close to and in front of the 
middle of the eye, the posterior one somewhat the larger. No barbel. 
The teeth in both jaws in villiform bands ; a naked space at the symphysis 
of the intermaxillaries. The intermaxillary bands are more than twice as wide 
as those on the mandible. Vomer and palatine toothless. The longest gill- 
raker on the anterior arch is slightly more than half as long as the eye. The 
number of gill-rakers on this arch is 25, 20 being below the angle. 
Pseudobranchie present, very rudimentary in some individuals, in others 
wanting or present only upon one side. 
The first dorsal is distant from snout (68 mm.), which is slightly more than 
length of the head; the length of its base (24 mm.) is about equal to width of 
the snout at the nostrils. The fin consists of 2 spines, the first of which is mi- 
nute, and 9 branched rays. The length of the longest spine, which is armed, 
is contained twice in that of the head (specimens examined imperfect). The 
second dorsal begins immediately behind the first, the membrane being con- 
tinuous. The anterior rays are longest (apparently about } the length of the 
head).
