42 A Contribution towards the Knowledge of the
Clerck, which I met with subsequently (July 25th) near the
"Forest School," between Wanstead and Walthamstow;
Theridion formosum, Clerck, Attus pubescens, F., and Cheiridium
museorum, Leach, found since in the same locality by Mr.
E. J. Pickard-Cambridge.
Class—ARACHNIDA.

Family—Drassidae.
Drassus lapidicolens, Walck.—Under stones and among
roots and debris of heather and other plants.
D. infuscatus, Westring.—An exceedingly rare spider;
among dead leaves and moss. I feel but little doubt that
this spider is identical with D. criminalis, Cambr.; the latter
being its scarcely-adult female form.

on bushes.
C. terrestris, Westr.—Among dead leaves and moss.
C. brevipes, Blackwall.—On bushes and boughs of low trees.

Hecaerge spinimana, Sund.—Dead leaves, moss, and debris.
Phrurolithus festivus, C. Koch.—At heather roots, and
among dead leaves, &c.
Family—Dictynidae.
Dictyna arundinacea, Linn.—On low plants.

of Dorset' (Sherborne, 1879-81) by the author, published by the "Dorset
Natural History and Antiquarian Field Club," where also references will
be found to Mr. Blackwall's magnificent folio, 'The Spiders of Great
Britain and Ireland' (London, 1861-64; Ray Society).
