Polyzoa of Queen Charlotte Islands. 207 
Diastopora suborbicularis (?), Hincks. 
[=D. simplex, Busk.] 
On shell. 
_[Greenland, Finmark, Britain, Naples. ] 
A single specimen occurs, imperfectly developed, which 
seems to have the characters of this species. A larger portion 
of the cell is free than is usual in D. suborbicularis ; but there 
is always much diversity in this respect, due to difference of 
habitat. The margin of the zoarium is slightly lobate, but 
this may be owing to the immature condition of the specimen.
