200 DEEP SEA FISHES. 



Dorsals separated by a space equal to the base of the first. Caudal end 

 filamentary. Origin of anal distant from the vent about four fifths of the 

 length of the eye ; fin rays much longer than those of the dorsal. Thirty- 

 seven pyloric c«ica. 



Brownish, with a greenish or olivaceous tinge in life ; linings of mouth 

 and body cavity black. 



Largest specimen about twelve inches. 



Macrurus capito sp. n. 



Br. r. 6; D. 10+?; A. ca. 100; V. 9 ; P. 23. 



Body and head compressed, caudal section decreasing in size rather 

 abruptly near the abdomen, thin flxrther back and tapering gradually to a 

 filamentary end. Head large, two ninths of the total length, three fourths as 

 wide as high, high and arched from the nape to the dorsal, descending from 

 the nape to the end of the snout. Suborbital ridges moderately prominent. 

 Crown slightly convex transversely. Snout sharp as viewed from the side, 

 broader than the interorbital space, longer than broad, as long as the eye, 

 with three angular prominences, median longest ; distance of the tip from 

 the inaxillaries three fifths of the length of the eye. Mouth medium, hori- 

 zontal, subtending nearly half of the eye. Eye large, as long as the snout, 

 as long as the mouth, as long as the base of the dorsal, one and one fourth 

 times the width of the interorbital space. Teeth very fine, in villiform 

 bands, larger in the outer series of the upper jaw. Barbel small, about one 

 third as long as the eye. 



Dorsal origin above the base of the pectoral ; first spine short and stout ; 

 second spine sharp-edged in front, with clo.se-set spinules and filamentary 

 end ; base descending rapidly backward. Second dorsal low, anterior rays 

 short and weak. Anal well developed forward, originating below the hind 

 portion of the base of the first dorsal, distant backward from the head about 

 the length of the orbit. Ventrals small, reaching the anal, inserted below 

 the origin of the pectorals. Pectorals medium, two thirds as long as the 

 head. Scales spinose, the spinules arranged in longitudinal series and so 

 long as to present a hairy or pilo.se appearance ; harsh over head and body, 

 especially on the three angles of the rostrum. Seven pyloric appendages.
