160 SOME NEW SECTIONS AT ILFORD.
things, teeth of Bos primigenius (Boj,), Rhinoceros megarhinus
(Christol), and Microtus gregalis ? (Pallas). With reference to
the last mentioned he writes, "A second upper molar of a small
Vole corresponds very closely with that of Microtus gregalis in
respect to the pattern of its prisms and also in size. It is just
possible, however, that this specimen belongs to Microtus
ratticeps and since it is somewhat damaged, lacking a prism, it is
certainly more desirable to make a provisional, rather than an
absolute, reference to Microtus gregalis. Whether it belongs to
one or the other it is an important addition to our list cf small
vertebrates from Ilford. The Voles from the Pleistocene
deposits of Ilford are now represented by five specimens indicat-
ing three species, viz., Microtus amphibius from the Uphall pits
(Cotton Coll.) and the Cauliflower Brickyard (a right upper molar
in my collection). Microtus arvalis or agrestis, from the Cauliflower
brickyard, in my collection. Microtus gregalis ? from Uphall."
We also obtained a few worked flints.
A small rounded boulder of greywether sandstone was
exhumed from the gravel.
Besides these two fossiliferous sections there are several
on the east of Ilford Lane, which have not yet yielded any
organic remains, but which are of special interest as they show
in addition the "trail." We measured the best of these which
was as follows : —
Surface soil .. ... 2ft.
(1) Contorted Drift (Trail) ... 4—51/2
(2) Sand ... ... nothing to 3
(3) Gravel ... ... 1—9
(4) Sand .. ... ... 1
(5) Gravel ... ... 4
(6) Sand and gravel ... ... 41/2 feet shown.
A few lenticular patches of manganese dioxide are exposed
in this section.

P.S.—Since writing the above we have obtained another
addition to the fossil invertebrate fauna of Ilford, viz., Planorbis
nautileus (Linn.) We are also able to confirm the occurrence of
Succinea oblonga (Drap.), a mollusc which, being confined to a
more northern tract, is no longer living in Essex.
