The Norwegian North Atlantic Expedition took it off Spitzbergen, Jan Mayen, East Iceland 

 and northern and western Norway, at depths of 22^ 649 fm. and temperatun - a rule below 



o° C. (down to —1.3 C), more rarely a little above o C. (to 1.5' C.l. The Expeditions "Lightning" 



and "Porcupine" took it in the Paeroe Channel, at depths of 345 550 fm. and temperatures oi ca. C. 

 We may say regarding the variety acuticostata Jeffr., consequently, that it is mainly bound 

 to the "cold area", but that it may also occur on the boundary region to the cold area 1 ). 



Distribution. Astarte crenata Gray is an arctic species, which is known from the north and 

 east coast of America down to Maine, Greenland, Jan Mayen, North and East Iceland, Norway down 

 to the Lofotens, Murman Sea, Parents Sea, Spitzbergen, Kara Sea and Polar Sea of Sibiria. The 

 bathymetric distribution is 5 — 650 fm. 



Jeffreys (1. c.l records Astarte acuticostata from the Osterfjord at Bergen, but I think this stateraenl 

 l'riele and Grieg also say (I.e.), that they have not observed it there, although they have dredged a good deal at tin 

 place. — Jeffreys gives I.eehe as his authority for its occurrence at Nova Zembla, but I have not been aide to find, where 

 Leche mentions it.
