CUSHMAN: WOODS HOLE FORAMINIFERA. 31 
with its large perforations on the ventral side and the irregular shape 
of the later chambers at once distinguish the species. In the character 
of perforations in the last chamber it is comparable to the last chamber 
of Orbulina and Cymbalopora which also have this coarsely perforate 
character. The specimen figured shows more than the usual irregu- 
larity of shape of the last chambers. These irregular chambers on 
the upper side (pi. 5, fig. 11), lack the bordering carina typical of the 
earlier ones. The Challenger dredged this species in the Indian and 
Pacific Oceans but nowhere else. Later it has been foimd to be a 
common littoral species. The majority of the specimens are regular 
and in general like figure 3 of the Challenger report referred to above.

A few specimens, apparently belonging to this species, were obtained 
from scrapings from the dock at Woods Hole.

This is probably the most abundant of the Foraminifera of the 
region. It was found at over fifty stations and always in very consid- 
erable numbers. It is most abundant on bottoms which may be 
classed as sandy mud or where at least there is a considerable amount 
of very fine material. It is small in size and on account of its color, 
which is often a gray brown, it may be very easily overlooked even 
with a hand lens. Li the majority of the dredgings it is the most 
abundant species.
