THE ANNALS AND MAGAZINE OF NATUEAL HISTOEY. [FIFTH SERIES.] No. 2. FEBKUAEY 1878. X IV. — Notes on British Spiders^ with Descriptions of some new Species. By the Rev. O. P. Cambridge, M.A., C.M.Z.S., &c. [Plate XI.] My last communication on British spiders was made two years ago (Ann. & Mag. Nat. Hist. 1875, xvi. pp. 237-260, pi. viii.). Since that time numerous other avocations have pre-vented any very extended researches in British arachnology. The results, however, of my own observations, and of the kind help of some other naturalists, are subjoined. From these results I have now to record five species supposed to be new to science, and five others previously described, but only dis-covered in Great Britain during the last two years. Ten species are thus added to our list of indigenous spiders, which now reaches a total of 484 species. Details of all these additions will be found below, as well as some rectifications of syno-nymy, with observations on habits and other points conceived to be of interest to araneologists, both in respect to the new additions and to some other species also. In the communication mentioned above, I remarked upon the very scanty materials extant for any list or history of Irish spiders ; and an appeal was made to Irish naturalists to collect and send me spiders from Ireland. I have had one kind response to this from Mr. T. Workman of Belfast, who has sent me a good many spiders during the last year, all of them, however, belonging to species already known, and one only being of any rarity — Drepanodus alhipunctatus^ Cambr. {vide Ann. & Mag.
