202 DEEP SEA FISHES. 



operculum, forward of the bases of the pectorals, first ray with a filament, 

 reachiug the anal. Vent close to the first ray of the anal, farther back than 

 the head by nearly the length of the orbit. Scales medium, spinose, with 

 close set, small, sharp, declined spinules arranged in eight or more longitu- 

 dinal series, hindmost prickles larger extending beyond the edge of the 

 scale. The scales of the head and snout are smaller and harsher to the 

 touch. The width of the scaly area between the nostrils is equal the width 

 of the snout at the lateral angles. Each angle of the snout is surmounted 

 by a rosette of small spines. Between the lateral line and the base of the 

 first dorsal there are seven rows of scales. Six pyloric appendages. 



Brownish gray, with silvery tint where scales are lost, or silvery gray 

 changing to brownish by brown puncticulations ; dorsal darker; linings of 

 body cavity and mouth black. Described specimen eight and one fourth 

 inches in length. 



Macrurus bobps sp. n. 



Br. r. 6 ; D. 10 + ? ; A. 95, V. 8 ; P. 21-23. 



In shape this species is similar to 31. Icucophceus ; its most patent distin- 

 guishing features are a narrower snout, a narrower interorbital space and 

 the backward positions of the ventrals. Body compressed, tapering to a 

 slender thread in the caudal section. Head one fifth of the total length, 

 somewhat compressed, width less than the depth and more than half the 

 length. Outline from snout to first dorsal convex above the nostrils and 

 again at the nape. Snout short, not as long as the orbit, less than twice 

 the interorbital space, distance of tip from maxillaries about equal the dis- 

 tance between the orbits which is two thirds of the width across the lateral 

 angles at the end. The angles in front of the nostrils are not much pro- 

 nounced, apices with groups of small spines. Mouth of moderate size, 

 maxillary extending below half of the orbit. Teeth small, in villiform bands, 

 subequal, larger in the outer row near the symphysis. Eye large, longer 

 than the snout, two sevenths of the head, length of orbits twice their distance 

 apart. Barbel small, one third as long as the eye. Suborbital ridge low, 

 rounded, scarcely prominent below the hind part of the eye. Dorsal origin 

 above the middle of the pectoral ; second spine of mcdiiun size, serrate, 

 probably ending in a filament ; base descending steeply backward. Second
