row of forauiina ; surface area small, uearly solid ; mouth iu same 
plane with surface large, semioval, curved margin, slightly raised, 
straight or proximal margin flat, slightly inclined inwards ; one or 
two foraniinated vesicles at proximal angles of mouth;" interior of 
cells nearly similar in shape to exterior; lateral connecting foramina 
numerous near base of wall, terminal two ; dorsal surface of opposite 
layers not separable, extremely thin ; w^alls of adjacent cells separable, 
glossy but uneven.

I have no doubt but that the fragments in my cabinet belong 
to this species, as they answer the very full description of Lonsdale, 
but it is to be hoped, after the publication of the present monogi-aph, 
that more attention will be given to the collection of Eocene Polyzoa. 
9. i]scHARA sp. 
There is a fragment of a species of Eschara (?) in my Eocene 
collection, which for the present I leave as above, as I am unable to 
identify it. The form is quite distinct from all others that I have 
described.

Zoariim, disc-shaped, attached by a short cylindrical hollow 
pedicle, situated on the edge of the disc. Zocecia, in opposite layers, 
but without intermediate laminai ; rows in each layer radiating from 
the centre, irregularly alternate ; cells globular, peristome prominent, 
bounded by a deep groove ; orifice round or slightly oval. Ooecia, 
large, semi-globular, covering the proximal portion of the cell ; 
" affecting more or less the size of the cellular mouth opening into 
vesicle within the cell." Surface sometimes provided with a minute 
tubercle near distal edge.
