(231) 9. South African Crustacea (Part X of S. A. Crustacea, for the Marine Investigations in South Africa). By the Eev. THOMAS E. E. STEBBINO, M.A., F.E.S., F.L.S., F.Z.S., Fellow of King's College, London, Hon. Memb. of New Zealand Inst., Hon. Fellow of Worcester College, Oxford. (Plates XVIII-XXVII of Vol. XVII. Plates XCVIII-CVII of Crustacea.) OF the thirty-six species noted in this contribution ten are regarded as new to science, and for three of them new genera have been named, Dairoides in the family Xanthidae of the Cyclometopa, Xeinostoma in the family Cyclodorippidae of the Oxystomata, and Hapaloptyx in the family Uroptychidae of the Galatheidea. Notice is taken of Dr. Ihle's identification of my genus NasinataHs, 1910, with Corycodus, A. Milne-Edwards. 1880, and the transfer of Corycodus disjunctives from the Eauinidae to the Cyclodorippidae. The specific validity of Platymaia turbynei is accepted, as proposed or suggested by Miss Eathbuu. Mr. Keppel Barnard has pointed out to me that the locality given in Part IX, p. 26, of this series for Hyastenus uncifer, Caiman, is misleading, since " Pietermaritzburg is at least 50 miles from the sea." Whatever the explanation may be, my authority was correctly quoted. Perhaps Pieterniaritzburg was only added to indicate whereabouts in Natal the " Umsunduzi Eiver " should be looked for, without any intention to imply that the marine species had visited the inland town. It may be worth mentioning that the paper has been unavoidably curtailed and its publication considerably delayed, owing to those gigantic troubles, still reluctantly subsiding, which have extended their interference to efforts the most unambitious and peaceful.
