The solitary specimen, from Station 14, differs from the usual 
form in having the test composed of fragments of considerable size 
from various organisms, giving it the rough appearance shown in the 
figure. In other respects it is sufficiently characteristic, and has an 
aperture at each end. Some of the specimens figured by Goes indi- 
cate a relationship with P. vesicularis ; they are from the Skagerack 
and Koster Island.
