O n some new Species of Exotic Araneidea. By the Rev. OCTAVIUS PICKARD-CAMBRIDGE, M.A._, F.R.S., C.M.Z.S., &c. [Received April 6, 1899.] (Plates XXIX. & XXX.) The twelve species of Araneidea described here belong to several families, and are from widely separated localities,-one species (each) from Bogota, Natal, and Madagascar, two from Singapore, and seven from Ceylon. Specimens of five of those from Ceylon were sent to me many years ago by the late Mr. G. H. K. Thwaites, of the Boyal Botanic Gardens, and of tw*o by Mr. Ernest E. Green, of Dickoya, Ceylon. The Singapore spiders were sent to me by Mr. H. N. Ridley, Superintendent of the Botanic Gardens. The Natal spider, an exceedingly fine and remarkable species of the genus Pollys C. Koch, was kindly given to me by Dr. F. N. Dimock Brown, together with some very characteristic coloured sketches 495 millim. 35 „ 24 „ 49 „ 135 „ 53 „ 106 „ 360 |
