The List of a hundred and eighty species which I give below includes, I believe, all the species that are known to inhabit Suffolk in 1937. Several have not previously been recorded. Many more of the 550 British kinds will be added in the future as the result of careful search. I have not attempted to give a complete list of the localities in which each species has been found [though such has been later inserted, as far as at present ascertained.—Ed.] but have recorded only my own unpublished localitity records. Most of my collecting has been carried out, besides Hemley, within the area bounded by Mildenhall, Brandon, Thetford and Bury St. Edmunds, and its duration unfortunately has amounted to very fevv days in all. This is a rieh area, which deserves much more attention. The saltmarshes, where Mr. Claude Morley and M r . H . St. J. Donisthorpe have recently discovered a species new to Britain (recorded by Dr. Randelf Jackson in the Trans, of the Suff. Nat. Soc. 1937, p. 279) Trochosa fulvolineata, Luc., at Hemley and Blythburgh, would also repay careful search. The little blue-bodied Spider, Physocyclus Simoni, Berl., was also new to Britain when I found it in the cellars of the Angel Hotel at Bury St. Edmunds in 1932, but I have since rediscovered it in similar situations in eight other counties. Previous records of Suffolk Spiders have comprised a list of species, rarely with any indication of locality, by your Hon. Secretary [on the authority of the late Revd. Octavius Pickard-Cambridge, M.A., F.R.S., of " Bloxworth Blue " fame, Wareham in Dorset] in the Victoria History of the County of Suffolk 1911, and scattered additions in the Transactions of the Suffolk Naturalists' Society and elsewhere.
