THE COMITY OF SPIDERS
species inhabiting particular regions or environments. It is believed
that a survey of our present knowledge of the geographical
distribution of our spiders will be of value in exposing our weaknesses
as well as our strength and, to ensure as complete a survey as possible,
careful search has been made through almost the whole literature
dealing with British spiders. This in itself must be my excuse for not
providing a list of references. I am, however, particularly indebted to
the writings of J. Blackwall, O. P. and F. O. P. Cambridge, G. H.
Carpenter, W. Evans, A. R. Jackson, W. Falconer, J. E. Hull, F. P.
Smith and D. Pack Beresford. Published records have been largely
supplemented by my own collections in 57 counties, and by a number
of manuscript lists of varying importance kindly placed at my
disposal. These manuscript lists include the following: F. O. P.
Cambridge (10 counties), W. Falconer (several counties), Warrington
Museum collection (teste W. Falconer several counties), British
Museum collection (several counties), Rev. H. Bloom (teste O. P.
Cambridge 8 counties), F. P. Smith (Middlesex), R. Hancock (teste
F. P. Smith Warwick, Worcester), Colonel Pickard (teste O. P.
Cambridge Argyll, Aberdeen), H. StJ. Donisthorpe (teste O. P.
Cambridge and A. R. Jackson Surrey), Miss G. V. Barnard (teste A.
R. Jackson Norfolk), G. H. Locket (teste A. R. Jackson Herts,
Middlesex, Northampton, Bedford, Kent, Cornwall), T. Savory (teste
J. E. Hull Wales), C. Morley (teste O. P. Cambridge and A. R.
Jackson Suffolk). I myself owe special thanks to Dr. A. R. Jackson
for inestimable assistance continued over a period of twenty years,
and to W. Falconer and D. Pack Beresford for the full lists of all their
records, which they have kindly extracted from their notebooks.
Counties may in certain respects be unsatisfactory units of area, but
as a rough guide to geographical distribution they have their
advantages. We all know the counties, and every map will show us in
which county we are collecting. We are brought up to
