OF THE UPHALL BRICKYARD, ILFORD. 211
I have obtained two more examples of Helix hortensis, and
additional granules of Anon ater. Also several specimens of the
Helicella, provisionally referred to in the previous paper (op. cit.)
as a variety of H. itala. It may be described as combining the
spire of H. virgata (Da Costa) with the umbilicus of H. itala.
The list of mollusca from the Uphall Brickyard is now so
exhaustive that there only remain eleven more5 to complete the
list from the Ilford district. One of these, however, Pisidium
astartoides (Sandb.), is totally extinct : it is a common form in
the Pleistocene deposits of the Thames Basin, and further
research would undoubtedly add it to the Uphall beds.
On one occasion I found a couple of the pharyngeal teeth of
a fish, together with the humerus and molar of a small vole,
which I submitted to Mr. E. T. Newton, F.R.S., who has
kindly identified them as probably belonging to Levciscus rutilus
(roach) and Microtus agrestis respectively. They are both new-
records. A couple of small incisors in my collection may
possibly belong to the last-mentioned. I have also obtained
many more mammalian remains, chiefly Rhinoceros leptorhinus,
Bos primigenius, and Equus caballus.
Annexed is a complete list of the Vertebrata obtained from
the Uphall Brickyard, copied, with additions, from Davies'
Catalogue.6 Mr. Hinton (op. cit.) also records the albatross
(Diomedia exulans, Linn.) on the strength of an ulna in the
Museum of Practical Geology, but I cannot agree with him in
considering it to come from these beds. I have also omitted
Ovis, which it should be remarked is given with a query.
It is curious that previous writers should have failed to note
the occurrence of Palaeolithic Implements in the Uphall series.
Indeed, until recently, when the above-mentioned author
recorded (op. cit.) two from the Cauliflower Pit, they were
unknown from the Ilford brickearth. I found several in situ in
the upper part of the gravel, and clearly in association with the
extinct mollusca. They consist of flakes, notched on the basal
side, so as to produce a saw-like edge, and are not derived, being
quite fresh and but little worn. I also obtained many waste
flakes—all more or less rolled—from the overlying bed of sand.
