Macrurus carminatus, new species. 
A single specimen, 248 millimeters in length, was obtained, September 
4, at station 871. It is most closely related to M. celorhynchus (Risso) 
Bonap. and to M. atlanticus Lowe, but differs in the number of fin-rays 
and in other characters. 
The body is less elongate and stouter than in M. Bairdii, Goode & Bean, 
though its greatest height (12.5) is, as in M. Bairdii, one-eighth of total 
length. The difference in general appearance is due to the fact that in 
M. carminatus the ventral contour retreats less rapidly. 
The scales are large, heavy, the free portions covered with long vitre- 
ous spines arranged in nine or ten rows. These scales resemble the old- 
fashioned wool cards. Hence the specific name, from carmen, a wool-card. 
The spines are thicker and more closely set than in M. Bairdii, and there - 
is no specialization of the central row. The number of scales in the 
lateral line cannot be determined, though it probably does not exceed 
100, but there are about five transverse rows above it and twelve below 
it, counting from the vent obliquely backward. In MW. Bairdii there are 
152 in the lateral line, six above and nineteen or twenty below. 
Length of head (21) contained a little less than five times in total 
length. Width of interorbital area (4) about equal to vertical diameter 
of orbit, and about one-fifth of the length of the head. Length of snout, 
horizontal diameter of eye, length of postorbital portion of head about 
equal (7). Length of operculum (35) half that of snout. 
Snout long, sharp, depressed, triangular, the lower surface more nearly 
parallel with the axis of the body thanin WM. Bairdii: The lateral ridges 
are pronounced and are contained in a straight line-under the eyes and 
upon the preopercula. Strong horizontal ridges continue from the supra- 
orbital margins to the gill-openings, parallel with the subocular ridges. 
Nostrils immediately in front of the orbit. Barbel very short. 
Teeth small, conical, somewhat recurved, arranged in villiform bands. 
Distance of first dorsal from snout (23.5) about four and one-half times 
the length of its base (5), its distance from anterior margin of orbit much 
less than the length of the head. First spine very short, hardly per- 
ceptible above the skin. Second spine about half as long (11) as the 
head, slender, unarmed. When laid back, its tip reaches the origin of 
the second dorsal (the filament is destroyed). The decrease in the 
length of the spines is very gradual, the sixth being nearly as long as 
the second, so that the fin is not so triangular in shape as in M. Bairdit. 
The second dorsal begins in the perpendicular from the seventh ray 
of the anal. The anal is much higher than in M. Bairdii, the length of 
the longest rays (2) nearly equal to half the width of the interorbital 
area. 
Anal fin inserted under the eighteenth scale of the lateral line (as 
nearly as can be judged from the distorted specimen). Its longest rays 
are as long as the width of the interorbital area. . 
Distance of pectoral from snout equal to twice its own length (11),
