VINE: ^s'OTKS OX YOKEDALE POLYZOA. 81 
This is not a common form even in the Scotch Carboniferous 
shales — in the Lancashire shales the best specimens are from Little 
Urswich — and as is common with many of the fossils from this 
district, rather ferruginous; specimens from Gleaston can only be 
recongnised by comparison with examples from other localities. 
Some of my examples, however, show the strong base and calcified 
stump to which the growing zoarium was attached.

There are only two or three fragments present, and these are 
confined to two localities. I cannot, however, satisfactorily identify 
tJie form, but the fragments have the same number of cells between 
the pinnae, but the obverse lacks the ornamentation of the common 
but beautiful Scotch species.

13. PiXNATOrORA sp. 
I possess minute fragments of two or three examples of 
Pinnatojwra that I cannot identify with any of the known forms. 
One specimen closely accords with the description of M'Coy's P. 
(Glauconome) grandis* in possesing three cells between the pinnee ; 
while another fragment very closely resembles the peculiar 
ornamentation of P, aspera^ Y. & Y., but the examples are too small 
for complete identification. 
14. PiNNATOPORA ? SIMPLEX sp. new, pi. X., fig. 4. 
The size of the Zoarium of this beautifully simple Finnatopora 
is at present unknown. In the example figured it will be seen that 
the branch is unornamented, and the Zoaecia uncovered by secondary 
deposits of calcareous matter. The cells are simple, and the general 
contour of the branch reminds one of a Cheilostomatous, rather tiian 
a Cyclostomatous Polyzoon. Between the rows of cells thei e are
