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 tj'pes. 



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 ^ of the length of the head. The postorbital part of the head is 2| times 

 as long as the eye, which is nearly round, its diameter equal to \ 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. Tlie 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. 



Pseudobranchise 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 j the length of the 

 head).
