summers of 1893-95 I spent considerable 
time collecting marine shells on the south 
side of Staten Island and vicinity and 
dredging iu Raritan and the Lower Bay, 
from the vicinity of Keyport, N. J., to-

dredging in these waters are somewhat 
limited, for the reason that they are

mud bottoms at the edges of the channels, 
at a depth of from three to five fathoms. 
The dredge used was a curved-toothed 
oyster rake, the inside lined with wire 
netting of % in. mesh, leaving about 
three inches of the teeth points free. 
At New Dorp, on a sandy point, at low 
water, I found many specimens of Nevertla 
duplicata (Say) Stimps. buried in the sand, 
awaiting the returo of the tide. On one

Ensatella Americana (Gould) Verr.,—fresh 
shells in fine condition. Between Oak- 
wood and Gitfords I could always find
