182 THE SPIDERS OF EPPING FOREST. English language. True it is that the study can boast of abundance of valuable embellishments bestowed by such well- known scientists as Mr. F. O. Pickard-Cambridge, the Rev. John Hull, Dr. G. Carpenter, etc., but the foundations laid in this country by the untiring industry of Mr. John Blackwall and the Rev. O. Pickard-Cambridge can hardly be expected to support the rapidly-increasing structure of araneological science superimposed by a few earnest students of this much-neglected order. A practical difficulty, too, presents itself in the scarcity of copies of Mr. Blackwall's Spiders of Great Britain and Ireland and the Rev. O. Pickard-Cambridge's Spiders of Dorset, and in the face of such facts I may be allowed, perhaps, to add my iota to the splendid efforts of these veteran araneologists. In the hope of affording assistance to prospective students of the order I feel justified in devoting a considerable portion of the space at my disposal to the consideration of the anatomy and classification of the Araneae, trusting that opportunities will arise later for the publication of more detailed generic and specific descriptions. It will be obviously impossible to publish full drawings of all the species enumerated, but I hope to illustrate many of the more important specific distinctions, by means of which the collector will be enabled to recognise at least the commoner and more striking of the Epping Forest Spiders. I find from experience that simple, diagrammatic drawings are of far greater practical value than heavily shaded productions of a more pretentious character, and I propose to model the present illustrations in accordance with this belief. In generic and specific descriptions, similarly, style and effect must be sacrificed to clearness, even at the risk of frequent iteration and monotony of expression. In order to facilitate reference the subject matter might, I think with advantage, be arranged as follows :— I. Anatomy, including description of anatomical terms. II. Classification. III. Practical Work, including collection, examination, and preservation of specimens and noting of habits. IV. Literature.
