Littoral distribution general throughout the 
region. Abundant in sand or mud, just below 
low-tide level, especially in harbors, estuaries, 
or other sheltered places, where it is also 
taken at depths of several fathoms. Shells, 
and occasionally living specimens, dredged by 
the Survey throughout the length of Buzzards 
Bay; much less frequent in Vineyard Sound. 
Shells recorded from depths of 2 to 13 fathoms, 
most frequently in mixtures of mud and sand; 
living specimens taken in depths as great as 6 
fathoms, though rarely found within the field 
of the dredging operations.

Buzzards Bay, Vineyard Sound, Nantucket. — 
Verrill. Katama Bay*, West Falmouth Har- 
bor*. (Osburn and Cole, collectors). Shells 
found in enormous numbers by Mr. Edwards 
on beach at Waquoit Bay, February 17, 1909, 
where they had been washed ashore. Accord- 
ing to Verrill this species is “peculiar to sandy 
shores, both above and below low-water mark, 
and it often occurs in immense numbers on 
the sandy flats laid bare by the tides. ” Rarely 
met with in the Survey dredgings, though 
(shells only ?) were taken on a few occasions, 
in one case at a depth of 14 fathoms.

mens dredged in 2 to 15 fathoms, most fre- 
quently on bottoms containing mud.
