THE BORING AT RICHMOND, SURREY. 789 
bulky zoaria are produced; and I have noticed the same features in 
a species on Hntalophora from the Greensand of Haldon Hill. 
Richmond series, Prof. Judd, slides 4 a, b, c, d, e. C. Moore’s 
(Meux Brewery), slide M. 1/27; poor specimen. 
Locality and horizon. Ranville; Great Oolite, Hampton Clif; 
my own cabinet, from Bradford Clay. 
5. Drasropora microstoma, Michelin, var. connectens (n. var.). 
Zoarvum irregular and occasionally proliferous, Zocwcia varying 
in character, sometimes only the peristome visible above the sur- 
face, at other times slightly decumbent, separated by interspaces, 
roughened by lines which appear to connect the peristomes of cell 
and cell; mouth circular, hp (normal) thick; cell bulging imme- 
diately below the mouth ; proximal part of the tube rarely visible. 
Richmond series, Prof. Judd, slide 4*a: type. 
On account of the peculiar way in which the cells of D. micro- 
stoma are separated in the zoarium, I prefer to place this form as a 
variety of that species rather than any other. 
6, Drasropora Lamovrovxt, J. Haime. 
Diastopora Lamourouxi, Haime, op. cit. pl. viil. figs. 1 ab, 
D. folsacea (pars), Bronn ; Blainville. 
There are in the Richmond washings a great number of specimens 
of Diastopora having a very robust habit. I do not think that 
these can be placed under any of the species of Berenicea given by 
Haime in his Monograph of the Jurassic Bryozoa. There are, how- 
ever, in his Group of DrasroporEs sIMPLEs two species, one D. La- 
mourouct and the other D. Waltoni, the latter from the Inferior 
Oolite of Cheltenham. The Richmond species is closely allied to 
D. Lamourovxi, if not identical with it. 
If I am right in identifying this robust form, I can only say that 
T have not previously met with it as a British fossil. The specimen 
figured by Haime has the cells long and tubular, with a circular 
mouth, and the peristome slightly raised. These are the charac- 
teristic features of the specimens under consideration. 
The synonymy of Diastopora foliacea, of Lamouroux, Bronn, and 
Blainville, has been well discussed by Prof. Brauns in his able paper 
on the Bryozoa of the Middle Jurassic of Metz, 1879, and he justi- 
fies the separation of D. Lamourouai on the ground of its simple 
habit, and also on account of the circular peristome. lea foliacea 
is a distinct operculate form, from the Inferior Oolite.

champs).
