• 2 LAMELLIBRANCHIATA. 



Exped. in the Barents Sea (76°3i'N. L., 45°36'E. L.) at 130 fm., bottom-temperature —i' C, as Nomann') 

 gives the maximum size to be 11 '"™. in the length and 18™"'. in height, a size never reached by 

 Z. elliptica so far as I know, but which might well agree with the present species. 



Remarks. From Lima gwyiii Sykes (= L.elliptica Jeffr. (non Whiteaves)), with which the 

 present species has some resemblance, it is distinguished by the following characters: the form of the 

 shell is higher; the ventral margin forms a steeper curve with the lateral margins; the radiating ribs 

 (fig. 5e) are sharp, not serrate. L. snbovata Jeffr. is also a nearly related species, but it has more 

 numerous (50 — 60) radiating ribs and is even more tumid.
