VINE: NOTES ON FOSSIL POLYZOA. 
Corallum thin and encrusting-, with delicate and apparently 
structureless walls, but not fused together. Corallites large and 
small, irregularly disposed ; but occasionally in transverse rows, 
large and medium size ; the smallest, however, larger than any 
calicular openings in the previous species. Monticules feebly devel- 
oped, marked by a clustering of a few corallites, rather larger than 
ordinary. 
Localities : Hurst, Richmond. Widel}^ distributed as a Carbon- 
iferous species. 
In the Geology of Yorkshire, Mr. Phillips describes Calamopora 
incrustans, and I have figured a few cells of a species, and drawn 
up the above description as if the present form was a coral — of 
w^hich I have serious doubts — to show the contrast between the 
present and Scotch specimens of C. onegastoma, M'Coy. The fig. is 
drawn by the aid of the Camera lucida, and I cannot, from the 
closest scrutiny of the surface, find sufficient evidence to associate 
the Yorkshire with the Scotch form. Yet I believe that the two 
forms may be united if other material was at hand to help me to do 
so. In the interspaces of the Scotch form there are peculiar porous 
interspaces which I pointed out and figured in my paper " Review 
of the Fam. Diastoporidse," Quart. Jour. Geo. Soc, 1880, and in one 
of the figs.* of Mr. Ulrich's there is a section of Eridoporamegastoma 
Ulrich, identically the same as my own, but without the least 
reference to the pages of the Quart. Jour, of the Geo Soc, where 
Ceramopora megastoma was described and figured four years previous 
to the description of Mr. Ulrich, unless he had described the form in 
a previous work unknown to me. It is not by way of complaint 
merely that I make a reference to this peculiar form, but to draw 
attention to Ceramopora megastoma of the Scotch beds, C, megastoma 
of the Yorkshire shales, Eridopora megastoma, Ulrich, an American 
form, and Fistulopora minor, M'Coy, as being species closely allied, 
if not identical. Mr. John Young, however, in the Ann. Mag. Nat. 
Hist., Dec, 1882, affords ample and interesting particulars in an able 
paper on the probable identity of C. megastoma^ M'Coy, w^th that of 
Fistulopora minor ^ M'Coy.
