 Macrurus carminatus, Goode, Proc. U. S. Nat. Mus., III., 1880, pp. 346, 475 (Nov. 23). 



The Fish Commission obtained individuals in 1880 in the same region, at 

 depths of 115, 155, 225, and 372 fathoms.

8. Macrurus asper, new species. 



The relations of this species appear to be with M. Bairdii, from which 

 it differs in (1.) its longer snout, (2.) the location of the vent, which is much 

 farther back, and (3.) the absence of keels upon any of its scales. 



The length of the specimen described is 322 millimeters. The body is 

 much stouter than in 3L Bairdii, its greatest height being contained 6^ times in 

 its length. The scales are small, strong, the free portions covered with vitreous 

 spines arranged in about seven rows ; there is no specialization of the central 

 row, as in M. Bairdii, though the median spine at the margin of the scale 

 projects most strongly. The number of scales in the lateral line is about the 

 same, there being about 150 ; there are 7 above and 18 below the line. 



Length of head contained 5|- times in total length. Width of interorbital area 

 a little greater than horizontal diameter of orbit and length of operculum, and 

 contained 4|- times in the length of the head. Length of snout about equal to 

 width of interorbital space and about one half the postor])ital portion of the 

 head. Snout triangular, depressed, its tip in the axis of the body, and nearly 

 on a level with the lower margin of the eye ; its lower surface forming an angle 

 with the body axis, about equal to that formed with same by its upper profile. 

 The superior ridge is pronounced anteriorly, but ends in advance of the con- 

 cavity in the interorbital space. The lateral ridges are prominent, and continue 

 posteriorly to the eye, with strong angular projections in front of the nostrils. 

 No ridges continued from supraorbital region. Nostrils rather close to the 

 eye. Barbel shorter than the eye. Tip of lower jaw under anterior nostril, 

 cleft of mouth under posterior margin of orbit. 



Teeth in the jaws in a very narrow villiform band, the outer series slightly 

 larger : those in lower jaw apparently in single series, moderate. 



Distance of first dorsal from snout equal to nearly four times the length of its 

 base, its distance from the anterior margin of the orbit equal to the length of 

 the head. First spine minute ; second spine nearly two thirds the length of 

 the head, and when laid down is far from reaching to the origin of the second 

 dorsal. When the fin is erect, its superior margin is nearly at right angles 

 to the plane of the back, and slightly convex. The distance between the two
