VINE : CARBONIFEROUS POLYZOA 
22. Ceramopora Megastoma. M. Coy. (Berenicea sp.) Vine 
Review of Fam. Diastoporidce. Quart. Journ. Geo. Soc, 
1880. 
This species is present in very large patches on Limestone, 
incrusting stems of Crinoids, and on Shells. 
Localities : — Hurst, Shales ; Richmond. 
In addition to the above, I have one slide on which are frag- 
ments of Ehabdomeson, and attached are what I consider to be 
Ooecia of the species. I regard the discovery of these in so 
many localites of so much importance as to merit a separate study. 
In these beds I have only found specimens on the sides* of one 
Genus. In many of the Scotch series I have found them on 
Glauconome, Ccriopora, and Hypliasmapora, and it is possible that 
we shall detect them on other species as well. 
I have thus gone over very carefully all the species which I 
can regard with any degree of certitude as being present in the 
Shales. The list is a large one for the localities chosen. The 
abundance of specimens present in a given quantity of material, 
is small when compared with the Scotch Shales, measure for 
measure. But few localities, however, in Scotland, rich as they 
are, have yielded such a variety of distinct types. 
I wish to direct the attention of students of Palaeontology to 
the Limestone Shale Beds of North Yorkshire, and in return for 
material from these beds, I shall feel a pleasure in naming speci- 
mens, or otherwise helping in this department of Palaeontology 
any one who is disposed to make a pleasure of work.
