The "Ingolf" has taken this species at: 



St. 86. W. of Iceland 76 fm. 12 valves of young (mostly quite young) 



specimens. 



87. - - no - 5 valves of young specimens. 



- 113. S. of Jan Mayen I 3°9 - 2 valves, 



- 104. N. W. of Iceland 957 - 1 valve of a young specimen. 



West Greenland. 



Here the species occurs commonly from the southernmost parts up to Melville Bay, on mud, 

 clay, shell and stone ground. The depths noted for living specimens lie between 10 and 235 fm. 2 ). 

 The maximum length amounts to 36 mm . 



East Greenland. 



A. elliptica has been taken by Danish Expeditions at Angmagssalik, Cape Dalton, in Scoresby 

 Sound and Forsblads Fjord, (3)10 — 30(50)^11., on mud, clay and stony ground, as also by the Germauia 

 Expedition at northern East Greenland (Mob i us, as A. sulcata). The maximum length amounts 

 to 30 n,m . 



I Jan Mayen.] 



Here, curiously enough, the species has not been met with. Posselt (I.e. 1898, p. 67) records 

 it from Jan Mayen and Copenhagen Museum as the authority or source, but this is due to some mis- 

 take, as our Museum possesses no specimen of A. elliptica from this island.
