About 50 specimens were moreover taken in 1900; their 

 label is unfortunately lost; thus the exact locality cannot 

 be stated. 



The species was previously taken both at the southern 

 and at the northern East-Greenland. The Nordenskiöld- 

 Expedition took 9 specimens off AngmagsaHk at a depth of 

 25 — 40 fms.; the ground consisted of clay with small stones. 

 The Kolth off- Expedition of 1900 took 9 specimens in 

 Mackenzie-Bay, N. of Franz Joseph-Fjord, at a depth of 6V2 — 

 10 fms. and on muddy ground (Hägg 1. с. p. 33). The Germania- 

 Expedition took it at Shannon-Island, Sabine-Island, Jackson- 

 and Clavering-Island at 4 — 10 fms. (JVlöbius I. с p. 251). 



All the East-Greenland specimens, which I have at hand, 

 are more or less compressed and as a rule extremely lengthened:
