Three specimens. Chalk. South-east of England. Mantell Coil. 
Two zoaria, one with crowded growth ; the other is a basal specimen 
showing both aspects. Upper Chalk. Xorthfleet. Purchased of 
Bryce AV right. 
A young zoarium, with the main branches 10 mm. long and having 
four lateral branches in 6 mm. Part of it is isolated and exposes 
both surfaces. Chalk. Gravesend. J. "Wood Coll. 
Two zoaria in flint. One is regularly pinnatifid ; the other, encrusted 
with Membrauipora, has a tendency to somewhat flamboyant 
branching. Upper (?) Chalk. Charing, Kent. Purchased of 
Professor T. K. Jones, F.R.S. 1881. 
Four large frondose zoaria ; in one the zoarium is 20 mm. high by 
25 mm. wide ; there are isolated fragments and two slides with thin 
sections cut from this specimen. The other is 17 mm. high and 
31mm. wide. In one the branches are crowded, and the branch^* 
are often dichotomous ; it shows the broad, flattened reverse surface, 
with, however, the median ridge still recognizable ; a small part of 
the obverse surface has been exposed, and shows many of the fine, 
pore-like apertures of the young zocecia. In another specimen the 
branching is more open and the tendency is flamboyant ; the back 
is more ridged than in the first specimen, and the young branches 
have no fine, pore-like apertures. Sections cut from this specimen 
are registered as D. 7095 [snpi-a). Upper Chalk. Gravesend.
