Rotalia rosacea d'Orbigny, '26, p. 273, no. 15. 
Discorbina rosacea Parker, Jones, and Brady, '65, p. 25, pi. 2, fig. 71; Brady, 
'84, p. 644, pi. 87, figs. 1, 4; Flint, '99, p. 327, pi. 72, fig. 3. 
This is one of the most abundant species of the region. It is foiuid 
free in the dredgings and also in great numbers attached to the stems 
of hydroids and to many other foreign bodies, as has ah-eady been 
noted. It may be obtained in quantity from the piles of wharves 
where there are hydroids. Anything that is stationary in the water 
for any length of time is sure to have its share of the shells of this 
species. 
Truncatulina lobatula (Walker and Jacob). 
Nautilus lobatulus Walker and Jacob, 1798, p. 642, pi. 14, fig. 36. 
Truncatulina lobatula d'Orbigny, '39a, p. 134, pi. 2, fig. 22-24; Brady, '84, 
p. 660, pi. 92, fig. 10; pi. 93, figs. 1, 4, 5; pi. 95, figs. 4, 5. 
Specimens of this species are met with throughout the region. It 
is one of the common shallow-water species of the North Atlantic. 
Truncatulina rosea (d'Orbigny). 
Rotalia rosea d'Orbigny, '26, p. 272, no. 7. 
Truncatulina rosea Brady, '84, p. 667, pi. 96, fig. 1, a, b, c; Flint, '99, p. 334, 
pi. 78, fig. 2. 
One of the most interesting finds of the summer was a single speci- 
men of this beautifully colored little species. It was obtained from 
the same lot of material scraped from the piles of the dock at Woods 
Hole in which the single specimen of Patellina corrugata was found. 
It is interesting to record its occurrence much farther north than its 
usujd West Indian habitat. Further search will probably furnish 
additional specimens. 
Pulvinulina lateralis (Terqucm). 
Plate 5, figs. 11, 12. 
Rosalina lateralis Terquem, '78, p. 25, pi. 2, fig. 11, a, b, c.

In the deeper waters of Vineyard Somid this .species is not uncom-
