Notes on the Penmdce in the Collection of the British Museum, with Descriptions of some new Species. By Edward J. Miers, F.L.S., F.Z.S., Zoological Depart-ment, British Museum. [Received February 12, 1878.] (Plate XVII.) Mr. G. E. Dobson, M.B., F.L.S., lately presented to the Trustees of the British Museum a remarkable specimen of Penceus, with the request that I should lay a description of it before the Society. In studying the affinities of this form, which is described below under the name of P. dobsoni, I found it necessary to revise the characters of the whole of the species of this large and difficult genus ; and al-though the materials existing in the national collection are not rich enough at present to permit of a complete review of the subject, it is hoped that the following notes on the species in the collection will contribute toward the elucidation of the genus, while the synoptical key to the genus appended will serve to indicate what appear to be the principal distinctive characters of the different species, and to mark what are desiderata in the collection of the British Museum. I have added some remarks upon the Funchalia woodwardi, and on the Penceus edwardsianus of Mr. J. Y. Johnson, showing that this latter species must be referred to the genus Aristeus of Duvernoy ; also a description of a species of Sicyonia not hitherto recorded. Penceus canaliculatus. Palcemon canaliculatus, Olivier, Encycl. Meth. Hist. Nat. viii. p. 660(1811). Penceus canaliculatus, M.-Edw. Hist. Nat. Crust, ii. p. 414 (1837); De Haan, Faun. Japon. Crust, p. 190 (1849).
