other. From other northern parts, however, var. paliiata exhibits 

 extreme diversity in tlie spire, ranging from the comparatively simple 

 coil to the raised or conical, the extended (var. clatior G. O. Sars), and 

 the elongated (var. coarctata G. O. Sais| 



var. compacta Jeff. —At the mouth of Loch Fyne. 



var. asstuarii Jeff. — Specimens taken from the river Deben at 

 Woodbridge correspond to those from the Belfast estuarine deposits. 

 L. rudis Mat. — A ribbed form from Guernsey is indistinguishable 

 from L. }:^rxnlandicd Menke, from the Arctic coasts, and stamps the 

 latter as no more than a variety. 



var. tenebrosa Mont. — A small turreted form of this variety was 

 found by Gwyn Jeffreys in the river Deben in Suffolk, and the same 

 form was also found by him in the Arctic Expedition of 1875, cover- 

 ing the rocks on the shore at Godhavn in Davis Strait. I have the 

 same thing from Tilbury Marshes. The finest specimens I have met 

 with of this variety come from the Bass Rock, a rocky islet at the 

 mouth of the Firth of Fortli. These correspond to Jeffreys' otherwise 

 too enlarged figure. 



var, similis Jeff. — Port Erin, Isle of Man (Leicester) ! 

 L. littorea L. — Mr. E. D. Marquand records this species, which 

 is otherwise extremely rare in the Channel Islands, as "of frequent 

 occurrence between tide-marks at Alderney."^ Alderney is nearly 

 thirty miles nearer the English coast than Guernsey, and is within ten 

 miles of the F'rench coast.
