The Kolthoff-Expedition of 1900 took a specimen in 

 Mackenzie-Bay, N. of Franz Joseph-Fjord, where the depth was 

 6V2 — 10 fms.; the ground was muddy (Hägg I.e. p. 44). 



The maximum length is obtained by the specimens from 

 Hekla-Havn, namely 3'8 mm. 



In a fossil state it was jtaken by Hartz in 1900 in the 

 following locality: 



Hurry-Inlet, opposite the anchoring place 10 valves 



(maximum length 4*25 mm.). 



Tellinidae. 



Tellina (Macoma) calcaria Chemnitz.

Expeditions, namely at Tasiusak at a depth of 20 — 30 fms. 

 (2 empty specimens of a maximum length of 33 mm.). 



^) These specimens were by Pos seit confounded with Axinus flexuosus 

 from the same locality for which reason Axinopsis orbiculata. has not 

 been mentioned in his: Østgrønl. Mollusker.
