During the Sweclish Arctic Expeditions of l'S98 and 

 1891). this remarkable species was obtained at the following 

 stations : 



in 1898: 

 stat. 1. lat. 7r 35' X., long. 22' 47' E., between Norway alid Beeren 

 Island, depth 350 m., bottom temp. + 3,95° C, gray-bluish 

 clay with sand, pebbles and shells, 10 VI, one spec 



» 2. lat. 73" 27' X., lon^. 23' 11' E., between Norway and Beeren 

 Island, depth 460 m., bottom temp. + 2,67° C, soft, fairly 

 unmixed, gi-ayish black clay. 12 VI, two spec 



» 7. lat. 77' 25' N., long. 27 30' E., north of Hope Island, depth 

 160 m.. bottom temp. — l,7i' C. yellow-brownish clay, 

 23 VI, one spec. 



other species, this form mast be regarded as identical with Leptognathia 

 longiremis Särs (non Lilljeborg). To avoid mistakes he proposes to call it 

 Leptoynathin Sarsi. Ås the most important characters he points out: ter- 

 minal segment of the metasome armed on each side with a small denticle, 

 basal part of the uropoda rather short, inner ramus long, two-jointed, other 

 ramus short. two-jointed, the hand of the chelipeds dentated also on the in- 

 ferior margin.
