1The 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 
frem American sources, have been added, where the work is of a systematic 
diagnostic character. The majority of the rather numerous European refer- 
ee pb omitted, as they have not been deemed pertinent to the sub- 
ject in hand.
