XVII.—On Pustulopora clavata of Busk, from the Wolf Rock, near 
Penzance.—By CHARLES W. PraAcuH, A.L.S. 
Read at the Spring Meeting, May 23, 1871. 
iG your Meeting on the 18th of May, 1869, I had the pleasure 
of exhibiting a branched specimen of Polyzoa, which I had 
noticed in a collection of Zoophytes, from the Wolf Rock, belong 
ing to Miss E. Carne, of Penzance. As it much attracted my 
attention, Miss Carne kindly allowed me to take it, so that I 
might ascertain whether or not it was new. Having no books or 
specimens in Cornwall, I was then unable to say anything about 
it, beyond expressing my belief that it differed from all the recent 
ones I had seen. The nearest in resemblance to it was one - 
dredged by Mr. J. Gwyn Jeffreys in Shetland ; and when I was 
with him in 1864, I picked out a few specimens from the dredged 
material. The first specimen of it was got in West Greenland, 
by Dr. Sutherland, and was named by Professor Busk, Tubulipora 
ventricosa, this trivial epithet being assigned to it because of its 
peculiar inflated tip. The peculiarity made me doubt that it and 
the Cornish specimen were of the same species.—The next speci- 
men that came under my notice was from the Crag Formation. 
As soon as possible, after my return to Edinburgh, I referred 
to “The Monograph of the Polyzoa of the Crag,” by Professor 
Busk ; published by the Palzeontographical Society in 1859; and, 
on my examining Plate XVII, fig. 1, and reading at p. 107 the 
description, I felt satisfied that Pustulopora clavata, figured and 
described there, was of the same species as the recent one from the 
Wolf Rock, and not Tubulipora ventricosa, of the Greenland and 
Shetland Seas ; and thus, although not new to Geology, it was so 
to our recent Fauna. A very pretty addition it is, and for it we 
are under great obligations to Miss Carne. Anxious to be correct, 
I resolved not to publish any notice of it until I had seen Pro- 
fessor Busk. That pleasure was afforded me, when in London in ©
