REPORT ON THE DEEP-SEA FISHES. 137 



Macrurus asper (PI. XXXVI. fig. A). 



Coryphse7wides asper, Giinth., Ann. and Mag. Nat. Hist., 1877, vol. xx. p. 440. 

 D. 11. A. 89. P. 25. V. 10-11. 



Snout short, slightly projecting beyond the mouth. Eye of moderate size, not much 

 shorter than the snout, and two-ninths of the length of the head ; interorbital space Hat, 

 wider than the eye. Mouth extending to below the middle of the eye. Teeth of the 

 outer series in the upper jaw stronger than the remainder. Barbel rather shorter than 

 the eye. Prseoperculum with the hind margin not excised, and subvertical, and with 

 both limbs densely scaly. Scales with five radiating series of long and slender spines. 

 There are six scales in a transverse series between the first dorsal fin and the lateral line. 

 Second dorsal spine considerably produced, armed in front with rather di-stant barbs. 

 The second dorsal fin commences at a short distance behind the first. The outer ventral 

 ray produced into a filament. Black. 



Habitat. — South of Japan, Station 237; depth, 1875 fathoms. One specimen, 

 13 inches long. 



Macrurus carinatus (PL XXXIII. fig. A). 



Coryphamoides carinaius, Giinth., Ann. and Mag. Nat. Hist., 1878, vol. ii. p. 28. 

 D. 12. P. 21. V. 8. 



Snout obtusely conical, projecting beyond the mouth, the cleft of which reaches nearly 

 to below the middle of the eye. Teeth of the upper jaw in a band, those of the lower 

 likewise crowded in front and in a single series on the sides. Barbel well developed, but 

 much shorter than the eye. Interorbital space flat, much narrower than the large eye, 

 the diameter of which equals the length of the snout, and is only a little less than one- 

 third of that of the head. The distance between vent and isthmus is nearly equal to the 

 length of the head. 



The scales are of moderate size and provided with a very strong median keel, 

 terminating in a projecting spine, and with several short and low ridges which converge 

 towards the median keel, or run nearly parallel to it. There are five scales in a 

 transverse series between the first dorsal and the lateral line. Prseoperculum with the 

 hind margin undulated, and with the limbs scaly. The second dorsal spine is armed 

 with rather small and somewhat closely set barbs. The distance between the two dorsal 

 fins equals the length of the base of the first. Pectoral fin rather more than half as long 

 as the head. Outer ventral ray produced into a very short filament. Brown. 



Habitat.— I^eox Prince Edward Island, Station 145a; depth, 310 fathoms. One 

 specimen, 21^ inches long.
