ADDITIONS TO THE PALAEOLITHIC FAUNA
The other additions to the fossil fauna of
the Uphall Brickyard will be indicated
throughout this paper by an asterisk (*),
I am able to list no less than eleven
additional land and freshwater molluscs,
thus bringing the total number from these
sections up to forty-eight. They are :—
* Agriolimax laevis (Mull.) ?
*Vitrea nitidula (Drap.)
Hygromia hispida (Linn.)
* Vertigo pusilla (Mull.)
* Succinea putris (Linn.)
*S. oblonga (Drap.) v. elongata (Braun.)
Planorbis lineatus (Walker).
Pisidium fontinale (Drap.)
v. henslowianum (Shepp.)
v. pulchellum (Jenyns).
*P. milium (Held.)
*P. pusillum (Gmel.)
There are now only six records which
I am unable to confirm, viz.:—Unio pictorum
(Linn.), Bythinia leachii (Shepp.), Planorbis
albus (Mull.), Planorbis corneus (Linn.), Pyra-
midula ruderata (Stud.), Vitrea fulva (Mull.)
Specimens of the first three are preserved
in the British Museum (Natural History)
and in the Museum of Practical Geology,
but no examples are known of the remaining
shells, which, however, all occur in other
Pleistocene deposits in this country. Pyra-
midula ruderata is the most interesting, for
although it has a wide distribution at the
present day on the mainland of Europe, it is
no longer an inhabitant of Britain, where it
is very rare as a fossil, one or two from
Copford and Clacton, and a single example
from Barnwell being the only specimens
extant.
The occurrence of Succinea elongata is note-
worthy, as it has not previously been recorded
from this island, either fossil or recent, though
it is still living on the Continent.4

the shell is figured.
