The height of the body is nearly equal to the length of the head, 

 and one-fourth of the total (without caudal) ; the least depth of the 

 tail is two-fifths of the height of the body ; head nearly as high 

 as long ; eye very large, its diameter being more than one-third of 

 the length of the head. Snout very short and obtuse, with the 

 upper profile descending in a very strong curve. Cleft of the mouth 

 oblique ; maxillary reaching to the angle of the praeoperculum and 

 terminating in a triangular dilatation. Scales smooth, those of the 

 lateral line enlarged. 



Coasts of Greenland and Scandinavia. 



Nilsson compares this species with Scopelus rissoi, but this has the 

 body much more elevated.

The height of the body is one-fifth of the total length (without 

 caudal), the length of the head two-sevenths ; the least depth of the 

 tail is two-fifths of the height of the body ; the depth of the head 

 contained once and three-fifths in its length ; diameter of the eye 

 a little less than one-third of the length of the head ; distance 

 between the posterior margin of the orbit and the praeopercular edge 

 one-half of the diameter of the eye. Snout short, obtuse, with its 

 upper profile descending in a strong curve, and with the jaws equal 

 anteriorly. The maxillary reaches nearly to the angle of the prae- 

 operculum, and is slightly and gradually dilated behind. The origin 

 of the dorsal fin is somewhat nearer to the end of the snout than to 

 the root of the caudal, above the root of the inner ventral rays ; its last 

 ray is before the vertical from the origin of the anal. The pectoral 

 extends to the posterior third of the ventral. Scales smooth, stiff.
