Whole valves, not to speak of living specimens, have not 

 been found at East-Greenland. And as it does not seem probable 

 that a bivalve of such a considerable size as Fecten islandicus 

 should have escaped notice it is to be doubted that the species 

 lives at East-Greenland. But wherefrom do then the taken frag- 

 ments originate? Do they arise from a submarine fossiliferous 

 layer or from a shell layer on land? This last hypothesis is sup- 

 ported by the fact that N. Hartz in 1891 — 92 found a small frag- 

 ment of a shell lying together with Saxicava arctica in fine clay on 

 «Rolige Bræ« near the Kobberpynt in the inner Scoresby-Sound, 

 76 feet above the sea-level, and this fragment has correctly 

 been recognized by Posselt as Pecten islandicus. Thus it 

 appears that we here have to do with raised layers with P. is- 

 landicus, how could this fragment otherwise be found on the 

 glacier! Hartz also writes: «These shell-fragments presumably 

 originate from deposits higher up along the edge of the glacier 

 and thus suggest that rather considerable changes have taken 

 place in the distribution of the ice» ^).
