observed in dredged material from more than fifty stations of all 
depths and on all kinds of bottom from mud to gravel. This is the 
largest jMiliolina found in the region. When the interior parts are 
extruded they are seen to be of a light brown color and in the majority 
of fresh specimens there is a small mass of protoplasm projecting from 
the aperture. In this species, however, the shell is too thick for the 
internal coloring to affect the whole color scheme of the, shell which is. 
pure white. In sand washed from a dredge haul this species can at 
once be detected as its chalky white shell stands out clearly against 
the darker background.

Specimens of this species were found in almost as many stations as 
the preceding but in fewer numbers. The smaller size and narrow 
oral contour will at once distinguish it from typical Miliolina seminu- 
hirn, but the two are very similar and it is a question whether this- 
should be considered as more than a variety of Miliolina seminulum. 
Both seem to occur in greater numbers in the deeper water.

This species is very common in the region. It is best seen as an 
attached form. On the piles of the wharf at Woods Hole it appears 
in great numbers attached to the stems of hydroids. In all parts of 
the region it is found in a similar manner, on hydroids and algae. 
In life the shell has a beautiful pinkish tinge, due to the color of its 
})rotoplasmic contents. When the interior protoplasm is protruded 
in living specimens the color is even more marked.
