A CONTRIBUTION TO THE FLORA OF THE COUNTY. 207
know least, although of the first importance, the distribution of
the various forms according to the soil and situation in which
they grow, are among other points of interest. This biological
survey should go hand-in-hand with a similar survey of the
flowering plants, and the land and freshwater molluscs particu-
larly, but other forms of life should not be ignored. Something
has been done in various parts of the world of late on these lines,
but nothing so far as I know in Essex.
In the compilation of the following list I have had the kind
assistance of, and desire to tender my best thanks to, Mr. W.
Cole, through whom I have been able to carefully examine the
collections belonging to the Essex Field Club; Mr. A. Gepp, for
assistance in consulting the specimens collected by Mr. Forster,
now in the Herbarium of the British Museum; Mr. G. Maynard,
who kindly compiled a list of mosses collected by Mr. F. Y.
Brocas, and now in the Saffron Walden Museum; Mr. W.
Sherrin, for the list of mosses collected by himself in Essex; Mr.
J. Wheldon, for naming the critical group of Hypnum known as
Harpidium; the Rev. E. N. Blomfield, for additions to the list
in the Victoria History of Essex; and Mr. H. N. Dixon for lists
and much help when in doubt.

tion contained in the following list of localities has been derived.
