extends much further backwards than the dorsal series, and, 



anteriorly, is lost on the side of the abdomen. These spines 



have smooth edges (not denticulated as in M. tracliyrhynclius). 



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



Macrurus holotrachys. 



Snout not much produced, as long as the eye, which is 

 large, its vertical diameter being considerably more than the 

 width of the interorbital space. Anterior edge of the snout 

 with three tubercles, one in the middle and one on each side. 

 Each scale with a median series of spiuelets, and with two 

 or more isolated spinelets besides. Upper and lateral portions 

 of the head covered with irregular rough scales, lower naked. 

 There are five scales in a transverse series between the first 

 dorsal spine and lateral line. Distance between the two dor- 

 sal fins scarcely equal to the length of the base of the first. 

 Second dorsal spine with small barbs anteriorly ; outer ven- 

 tral ray produced into a filament. No scaleless fossa on the 

 temple. Barbel very small. No bands or spots. 



Deep sea, east of the mouth of the Rio Plata (Station 

 320), 600 fathoms. 



Macrurus fasciatus. 



Snout not much produced, shorter than the eye, which is 

 very large, its vertical diameter being considerably more than 

 the width of the interorbital space. Scales with from eight 

 to ten subparallel keels. Upper and lateral portions of the 

 head covered with small rough scales, lower naked. There 

 are four scales in a transverse series between the first dorsal 

 spine and lateral line ; distance between the two dorsal fins 

 equal to tlie length of the base of the first. Outer ventral ray 

 produced into a filament. No scaleless fossa on the temple. 

 Barbel small. Whitish, with broad irregular blackish bands 

 across the back. 



West-coast of the southern extremity of South America 

 (Stations 305, 300, 311), 120-245 fathoms. 



Coryplicenoides rudis. 



Snout obtusely conical, projecting beyond the mouth, which 

 extends backwards to below the middle of the eye. The 

 outer series contains stronger teeth in both jaws. Barbel 

 about as long as the eye. Scales equally rough over the whole 

 of their surface, the spinelets being subequal in size, densely 

 packed, and not arranged in series. There are eight scales 

 in a transverse series between the first dorsal and the lateral
