a. Normal arrangement of cells. 6. Basal colonial growth with occium. 
This is a very variable species, and I was tempted to give some of 
the forms, at least, the varietal name “ producta,” on account of the 
cells being much produced at the distal extremities (fig. 2, a). In 
some of the specimens this feature is very prominent (slide 2 a); but 
as it is characteristic of the Bradford-Clay Stomatopore generally, I 
think that it would be unwise to increase the already too abundant 
difficulties of the paleontologist. It may be well, therefore, to give 
the following diagnosis, worked up from a fine series of specimens. 
Zoarium irregular, branches free, and sometimes anastomosing. 
Zowcia elongate, produced at the distal extremity of the cell ; orifice 
circular; peristome thick and slightly contracted, giving to the cell 
a bulgy appearance in some specimens just below the orifice ; tubes 
finely punctured. Occra a distended cell, very bulgy in the middle, 
sometimes single, occasionally in clusters. 
Richmond series, Prof. Judd, slides 2a, 6, ¢. Not represented 
among Mr. Moore’s specimens. 
Horizon and locality. Great Oolite, Kidlington, S. dichotomoides 
type. Intermediate between the Inferior- and Great-Oolite species. 
S. Waltoni (typical), Bradford Clay and Cornbrash. Mr. Walford 
quotes Forest Marble (local work).

I have not given in the above the several synonyms or references 
which Haime places under the name. In my own Report the 
form referred to, as peculiar to or characteristic of the Inferior-Oolite 
series, may be referred to again as D. pellucida. The present 
forms are characteristic of the Great-Oolite series, and are well
