fossils in the Harwich Cliff, and "Shells on the Sands of the Shore"
(P. 377).
In 1852 a most interesting paper on the fossil land and fresh-water
shells of the Copford Marl, by Mr. John Brown, F.G.S., was pub-
lished in the "Journal of the Geological Society."
A "List of Land and Freshwater Shells found in the neighbour-
hood of Sudbury," by William Doubleday King, of Sudbury, was
published in the "Zoologist" for 1853 (vol. xi., p. 3913), containing
sixty-three species found by him in the Valley of the Stour. They
appear to have been collected chiefly on the Suffolk side, but the
few freshwater species found in the River Stour may fairly be
reckoned as Essex shells. The most remarkable record in the
paper is that of Cyclostoma elegans, noted as occurring "on a bank
near the village of Belchamp, large, and mostly of a buff or clay
colour." The three villages so named, Belchamp St. Paul, Belchamp
Otten, and Belchamp Walter, are all in Essex, and this record
appears to be the first for the species in the county. The form noted
is evidently the var. ochroleuca, which I have invariably found to be
larger than the purple-spotted one.
No systematic list of recent Essex shells appears to have been
published till our member, Mr. Henry Laver, contributed his paper
"On the Land and Fresh-water Mollusca of the District around
Colchester" ("Trans. Essex Field Club," vol. ii., 1882). In this
he made record of seventy-five species, of which sixteen are not
to be found in my list, and eleven of my record were not found by
him, viz. :—
A few notes on Mr. Laver's paper by myself appeared in "Journ.
Proceedings, E.F.C," vol. ii. pp. lix.—lx.
The next paper is by Mr. J. French on the "Recent Mollusca
of Felstead" which appeared in the Essex Naturalist, vol. ii.,
pp. 1-3, with corrections and additions in the same volume, p. 46 ;
showing altogether sixty-two species, of which fifteen are not to be
found in my list, and twenty-three of mine are not recorded in his:
