Living specimens of this species were dredged in Vineyard Sound, 
“Fish Hawk” station 7723, and in Buzzards Bay, “Phalarope” 
station 82. 
All the specimens seen were of the type called by Sars L. granulata 
which Brady and Norman consider as the younger stage of L. guttata 
(Norman). The animal of the guttata type of shell needs to be fully 
studied to make certain that the two are really the same species. A 
fairly complete series of figures of the appendages is here given, includ¬ 
ing that of the copulatory organ of the male. 
This species does not seem to extend so far north as does the pre¬ 
ceding, being found from Norway through the Mediterranean. Brady 
and Crosskey (’71) record it from the post-Tertiary clays of Portland, 
Maine.

This species seems to be very common in the region, especially 
in comparatively shallow water, where it appears to live up among 
the eel grass and hydroids rather than on the bottom. It was taken 
in the Eel Pond, Wood’s Hole, on July 15, 1905, in numbers, from 
hydroids and other material scraped from the piles of the wharf of the 
United States fish commission station, and in great numbers among 
eel grass and hydroids near the surface from the “Gulf of Canso,” 
August 3, 1905. It was also found living in material dredged in 
Vineyard Sound, “Fish Hawk” stations 7716, 7723. In these deeper 
places it was rarely met with and then only as occasional specimens.
