210 rev. o. p. Cambridge on [Mar. 4, March 4, 1873. John Gould, Esq., F.R.S., V.P., in the Chair. Mr. Edwin Ward sent for exhibition the original leg-bones of Dinornis maximus, described and figured by Professor Owen in the Society's ' Transactions ' (vol. vi. p. 497, pis. lxxxix., xc), belonging to Col. Michael. The following papers were read : — 1 . On the Spiders of St. Helena. By the Rev. O. P. Cambridge, M.A., C.M.Z.S. [Keceived February 1, 1873.] (Plate XXIV.) In a former paper (Proc. Zool. Soc. 1869, pp. 531-544, pi. xlii.) twenty species of Spiders were recorded and described from a collection received from Mr. Melliss, by whom they were captured in the Island of St. Helena. Since then I have received from the same gentleman two other collections, in which, in addition to most of the species before recorded, I have found twenty-three others : among these, eleven appear to be undescribed, while, of the re-mainder, five are indigenous to Great Britain, Segestria senoculata, Tegenaria civitis, Scytodes thoracica, Theridion tepidariorum, and Linyphia leprosa ; two have been also received from Ceylon and India, Pholcus distinctus and Artema convexa ; two are European, Argyrodes epe'irce and Xysticus grammicus ; and two are Egyptian, Latrodectus erebus and Tetragnatha pelusia. The European stamp observed upon in regard to the Spiders of the former collection is thus equally marked in those now recorded and described, three only of those already described belonging to species not hitherto recorded as European. According to the present and former papers, the known Spiders of St. Helena thus number forty species, a number which will, I doubt not, be greatly added to when a closer and more extended search shall have been made. I understand that Mr. Melliss has ceased to reside in St. Helena, so there is no more chance of further discoveries in Arachnida from his exertions ; but for what he has done, and so kindly placed within my reach as materials for the present and former papers, I desire now to return him my very heartiest thanks.
