distance from the first, the distance being equal to the length 

 of the head. 



North-east of New Zealand (Station 169), 700 fathoms. 



Coryphcenoides JiUcauda. 



Snout considerably projecting beyond the mouth, pointed in 

 the middle ; it is twice as long as the eye, which is unusually 

 small, only half as wide as the interorbital space. Mouth 

 rather wide, extending beyond the centre of the eye. Teeth 

 villiform, in very narrow bands. Barbel minute. Praeoper- 

 culum with the angle produced backwards, broadly rounded 

 and crenulate on the margin. The terminal portion of the 

 tail is prolonged into a long filament, more slender than in 

 any of the other species. Scales thin, cycloid, and deciduous, 

 six or seven in a transverse series between the first dorsal spine 

 and the lateral line. The second dorsal spine slender, with 

 the barbs in front very inconspicuous and sometimes entirely 

 absent. The distance between the two dorsal fins is less than 

 the length of the head. 



Deep sea on both sides of the South-American continent ; 

 Antarctic Ocean. (Stations 157, 299, 325.) 1800-2650 fathoms. 



Coryphcenoides variabilis. 



Snout obtusely conical, projecting beyond the mouth, the 

 cleft of which extends behind tlie middle of the eye. The 

 teeth of the outer series are visibly stronger than the remain- 

 der. Barbel nearly as long as the eye. The interorbital 

 space is flat, its width being much more than the diameter of 

 the eye, which is comparatively small. The scales are pro- 

 vided with five ridges, each ridge composed of several spines, 

 and the central ridge being the strongest. There are eight 

 scales in a transverse series between the first dorsal and the 

 lateral line. Lower limb of the praeoperculum scaleless. 

 Second dorsal spine armed with barbs in front, which are 

 rather distantly set. The second dorsal fin commences at a 

 distance from the first which is less than the length of the 

 head. 



Midway between Cape of Good Hope and Kerguelen's 

 Land ; South of Australia ; Mid-Pacific ; south-west of Juan 

 Fernandez. (Stations 146, 157, 246, 271, 300.) 135-2425 

 fathoms. 



Coryphcenoides affinis. 



Snout obtusely conical, projecting beyond the moutli, the 

 cleft of which extends behind the middle of the eye. The
