does not mention any American occurrences except Greenland. 

 I have not been able either to find the species recorded as 

 American in other lists by Packard, Dall, Bush, Whiteaves 

 etc. It is, indeed, only mentioned as a Greenland species by Dall 

 in his Synopsis of the Fam. Cardiidae and of the JNorth-American 

 species'). Its real distribution is thus: the colonized West- 

 Greenland; the south-eastern Greenland; East-Iceland; the north- 

 western Norway.

The Germania-Expedition already took it at East-Green- 

 land, but the locality has not been recorded (Möbius 1. с. 

 p. 251). 



The Nordenskiöld-Expedition of 1883 took it off Ang- 

 magsalik (65° 40' N. 35° 32' W.) at a depth of 25—40 fms. and 

 on clayey ground. 



The Kolthoff-Expedition of 1900 took 3 specimens in 

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

 — 19 fms. and on muddy ground (Hägg 1. с. p. 50). 



Möbius states the length to be 70 mm. Hägg states it 

 to 64 mm. The largest of the specimens I have at hand, 

 namely those from Angmagsalik and from Sabine-Island, measure 

 53 — 55 mm. 



Fossil it has been found by Ryder in the Terrassepynt 

 on the east-side of Rypefjord, inner Scoresby^Sound. I have 

 not seen the specimens, but they have been determined by 

 Posselt^).
