1 The writer is largely indebted to the work of Dr. W. H. Dall, Alaska 

 Land and Fresh-Water Shells, for a large proportion of the references in 

 the generic portions of this monograph. A number of references, principally 

 from American sources, have been added, where the work is of a systematic 

 diagnostic character. The majority of the rather numerous European refer- 

 ences have been omitted, as they have not been deemed pertinent to the sub- 

 ject in hand.
