St. Lawrence and Brady and Crosskey (’71) record it from the post- 
Tertiary of Portland, Maine.

Cythere alba Baird, ’50, p. 170, pi. 20, fig. 6. 
Living specimens of this species were obtained but once, and then 
from hydroids and other material scraped from the piles of the wharf 
of the United States fish commission station at Wood’s Hole. In 
contrast to the preceding species it is more southern, and occurs 
almost entirely in the littoral and laminarian zones and in tidal rivers. 
As these portions of the area were not fully investigated it may be 
found to be common in the region. There were certain discrep¬ 
ancies between the specimens and the published figures of the animal 
parts and more material may show it to be an entirely distinct species. 
Cythereis villosa Sars.

The shells of this species are fairly common in the deeper parts of 
Vineyard Sound, and were especially noted at “Fish Hawk” stations 
7723 and 7727. It is a northern species on the European coast and 
is recorded by Brady (’70) from the Gulf of St. Lawrence. It also 
occurs in the post-Tertiary of Canada.
