Head short, rather compressed ; snout short, obliquely truncated in front ; cleft of 

 the mouth wide, lateral, extending to beyond the centre of the eye ; intermaxillary not 

 much shorter than the maxillary. Teeth in villiform bands in both jaws ; barbel very 

 small. Interorbital space convex, its width being considerably more than the diameter 

 of the eye, which, in a specimen three feet long, is equal to the length of the snout and 

 one-fourth of that of the head. The scales are equally rough over the whole of their 

 surface, all the spinelets being directed backwards ; there are seven or eight scales in a 

 transverse series between the first dorsal fin and the lateral line. Head entirely covered 

 with small scales. Anterior dorsal spine armed with numerous small, closely set barbs ; 

 outer ventral ray produced into a long filament. Distance between the vent and isthmus 

 two-thirds of the length of the head. 



Habitat. — North Atlantic ; a large specimen nearly three feet long, which has served 

 principally for the above diagnosis, is from Sognefjord, Bergen, and several young 

 specimens were obtained between Shetland and the Fteroe Islands during the cruise of 

 the "Porcupine" and " Knight Errant," in from 200 to 500 fathoms. The occurrence of 

 this species on the east coast of the United States is reported from lat. 41° 32' N., 

 long. 65° 55' W.; depth, 524 fathoms.'

 omitted to examine the dentition.
