VINE: NOTES ON YOEEDALE POLYZOA. 
97 
H7jpJmsmopora, and I siig-gest, as a provisional placement, a family 
name that appears to me to be appropriate. It may be that further 
researches among the Sub-Carboniferous Polyzoa on the other side 
of the Atlantic may institute links by which the species may fall in 
naturally with some other of the Carboniferous groups. At present, 
however, I know of no British forms that could be satisfactorily 
used for that purpose. 
Horizon and,,Locality : Yoredale ; Gleaston Castle, Holker Park, 
North Lancas. Ilurst, North Yorkshire. 
35. STRECLOTRYrA (?) var. MINUTA, var. new, pi. X., figs. 7, 8, 9. 
The Zoarium of this beautiful minute form is smaller than »S\ 
j^icklisii, but the cell ari-angement is the same, only that in some 
of the examples of the variety the cells are more compressed, and 
the young cells of the branches are rounded at the distal extremity 
(pi. X., fig. 7a), and rather differently shaped. In the type species 
these rounded cells, at least in my specimens, do not appear. In 
this minute variet}^ too, the area beneath the cell orifice (pi. X., 
fig. 8a), is well marked. In all probability when the species becomes 
more fully known there will be no necessity for the distinctions 
between type species and variety, but I believe that it will be better 
for the Palaeontologist to direct attention to the varietal characters. 
Localities, <i;c. : Yoredale ; Gleaston Castle, Holker Park. 
Associated with the Polyzoa of the North Lancashire rocks, 
there are a number of fragments of different species that I cannot 
help but regard as Ovicells. These are so varied in their characters 
that for the present I can only make reference to them, in the hope 
that at some future time I may be able to furnish a paper on these 
reproductive chambers especially. There are also a few remaining 
examples of species closely related to American varieties, these I 
may also be able to attack, but at pi esent time I should have to rely 
upon MS. names which have been supplied to me with American 
undescribed examples. 
Description of Plate X. 
With the exception of 8a, the rest of the figures are drawn with 
camera lucida and magnified about 30 diameters.
