Distribution probably very general throughout 
the muddy shores and shallow waters of the 
region. Extremely abundant at certain points 
such as the Eel Pond, Great Pond, Wareham 
River, etc., and perfectly at home in waters 
which are decidedly brackish. Owing to its 
littoral habitat it was rarely taken during the 
survey dredging, except at stations close to 
shore. In deeper waters dead shells were oc- 
casionally met with, these having probably 
been transported by hermit crabs.

Shells generally distributed and of great abund- 
ance in both Vineyard Sound and Buzzards 
Bay, dredged in from 1 to 19 fathoms, on every 
sort of bottom; living specimens abundant 
throughout the Sound and along the eastern 
shore of the Bay; rarely recorded from the 
deeper portions of the latter. — Survey. The 
shells of this species are widely transported by 
the smaller hermit crabs, probably being the 
ones most commonly chosen by P. annulipes.
