Marine Shells of Massachusetts. 269 
This species, which, with its numerous varieties, is 
accurately described and figured by Kiener, was found 
on the rocks at Martha’s Vineyard by Mr. Seabury. 1 
have not seen it at Nantucket or at New Bedford, but 
have found the Fusus cinéreus in situations, where I 
should expect to see this species. I have also looked 
for it without success upon the rocks at Wood’s Hun in 
Falmouth.

` This species, as it occurs on our shores, is very accu- 
rately described by Say. The canal, however, is not 
longer than the spire, but is of equal or less length. 
This shell is not found north of Cape Cod, and but 
rarely at New Bedford, where I have found but three 
or four specimens, very old and worn. At Nantucket I 
have found but a single worn specimen. Say remarks, 
however, (but his observations did not embrace New 
England,) that this species is rather common. For a 
considerable number of specimens I am indebted to 
Mr. Seabury. i
