Cape Cod to South Carolina. Not uncommon in Vineyard Sound,

from Casco Bay by Dr. Mighels, but as this habitat has not been con- 
firmed subsequently, it was probably based on an erroneous ideutifica- 
tion. Fossil in the Post-Pliocene of Canada (Dawson).

are nearly all clear white and translucent, although of equal size.
