F. R. Wollaston and to Mr. W. E. Ogilvie-Grant for the opportunity of examining the spiders described in this paper. Some were obtained during the B.O.U. Expedition to the Mimika River, 1909-11, but the majority were collected by the Wollaston Expedition about the camps on the route from sea-level to the foot-hills in the neighbourhood of the Setakwa and Utakwa Rivers between September 1912 and March 1913 — that is, in the winter half of the year. Important collections from New Guinea and the neighbouring islands have been previously worked out by Dr. C. L. Doleschall, Professors Thorell and VOL. XX. — PART XIV. No. 1. — July, 1915. 3 p
