Several frag-ments belong-iug- to this species are rather abundant 
in the shales, and although Mr. G. W. Shrubsole at one time 
regarded Actinostoma fenestratum. Young & Young, as the perfect 
form of this species, he does not give this as a synonym in his later 
paper. It is to this species, however, that Mr. Shrubsole noticed that 
Falo&ocoryncB were more frequently attached, "for out of ninety- 
seven specimens of Palceocoryna, eighty-five are either attached to 
polypite-face of F. nodulosa or associated with it, while twelve are 
only free and unattached."*

I have not the least doubt but that specimens belonging to this 
species may be found in the Lancashire shales ; I have only a few 
small fragments in my collection.

The detached parts of the zoarium of F. nodulosa belonging to 
this group of " organisms," are very abundant in the North 
Lancashire shales. They are well preserved and very fine. As, 
however, Prof. Duncan was the first to work out the group, I have 
only given the references to the original papers, because, however 
the forms may be regarded at the present time — the admirable
