The Arctic regions have such a uniform mollusk-fauua, and, especially 

 in the vicinity of Greenland, have been so often and so thoroughly 

 searched for mollusks that it was not to be expected that the small col- 

 lection which Mr. Turner was able to make should contain anything 

 new or remarkable. At most, it might afford some interestiiig facts 

 bearing on geographical distribution and the special fauna of Labrador. 



My surprise, therefore, was great, when on examining the specimens 

 in spirits, I found examples of a moUusk not only new to science as a 

 species, but belonging to a generic group which does not appear to be 

 known. Moreover, the specimen best developed was over half an inch 

 in length.
