- 2 LAMELLIBRANCHIATA. 



Exped. in the Barents Sea (76°3i'N.L., 45°36'E.L.) at 130 fm., bottom-temperature — 1° C, as Nomann 1 ) 

 gives the maximum size to be 11 ram . in the length and 18 mm . in height, a size never reached by 

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



Remarks. From Lima gwyni 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. subovata Jeffr. is also a nearly related species, but it has more 

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