NOTES ON THE ARACHNIDA OF EPPING FOREST. 315 Britain, is one of the most beautiful among the many remarkable forms of micro-fungi growing on old dung. It was found by Mr. E. S. Salmon. At the next Fungus Foray of the Club it is intended to make an exhibit of drawings of some Essex Micro-Fungi. FURTHER CONTRIBUTIONS TOWARDS THE KNOWLEDGE OF THE ARACHNIDA OF EPPING FOREST. By F. O. PICKARD-CAMBRIDGE, B.A. A first contribution towards the knowledge of the Arachnida (Spiders, "Harvestmen," "False-scorpions" and Mites) of Epping Forest was published in the Trans. Essex Field Club in 1883 (vol. iv., pp. 41—49), by my uncle, the Rev. O. Pickard-Cam- bridge. There has not, to my knowledge, been any serious collecting done in the Forest itself, or even in the County of Essex, since that time, except by myself in the Dunmow district in 1889. This year, however, through the zealous energy of Mr. William Cole, the subject was again brought to the attention of Members of the Field Club, and on the occasion of the Annual Fungus-Foray a definite effort was made to increase the know- ledge of this group already gained and to add to the published list of species. Although the Foray was held rather late in the season for arachnological research (for the majority of spiders have by that time retired into winter quarters), still a very encouraging addition was made to the list, chiefly through the efforts of Mr. F. P. Smith, whose articles on British Spiders now appearing in Science Gossip will, it is hoped, arouse some interest in the subject amongst Field Naturalists in general. Altogether, on the occasion of the Fungus-Foray on October 6th, 1900, 42 species of spiders, including one "Harvestman," were added to the previous list which accounted for 57 species of spiders, 3 "Harvestmen," 3 "False-scorpions," and 4 Mites. Amongst those added were a few of the largest and most interesting of British spiders—Amaurobius ferox, for instance, a
