HABITAT. On shell, probably from deep water. 

 LOCALITY. Shetland (Barlee). 



This species is evidently allied to L. Pallasiana, and 

 especially to the variety with a much elevated peristome. 

 At the same time, in the absence of specimens, I do not 

 venture to pronounce them identical. Judging from the 

 description and figure, there are several points of difference 

 between them. The cells are broader in L. canthari- 

 f or mis, and very distinctly granulated, a condition which 

 1 have not observed in L. Pallasiana. The mouth, which 

 is definitely horseshoe-shaped in the latter, seems to be 

 very irregular in form in the present species, while the 

 peristome is much more highly developed in L. canthari- 

 formis than I have ever seen it in L. Pallasiana (compare 

 Plate XXXIII. figs. 3 and 4) . Provisionally at least the 

 two must be accounted distinct.
