Show 318 MR. E. A. SMITH ON THE [Apr. 1, I have been unable to discover the existence of any island name near New Guinea, although that region would be a correct habitat for this species. Perhaps " new " should read near, which would then clear up the doubt with regard to Ascension Island, but I very much question the occurrence of this shell in the Atlantic. All the species enumerated hereafter, with the exception of the three species of Marginella and Lanthina globosa, are represented in the British Museum by specimens from Ascension Island. The greater part were received from Staff-Surgeon T. Conry a few years ago, and partly recorded in the Ann. & Mag. Nat. Hist, for 1881, vol. viii. pp. 430, 431. I. GASTROPODA. PISANIA PUSIO (Linne). Two specimens of this common species were obtained by Dr. Conry, which agree in all respects with typical examples from the West Indies. It has not, I believe, been noticed before from the eastern side of the Atlantic. COLUMBELLA (MITRELLA) CRIBRARIA, Lamarck. Hab. Ascension (Quoy &f Gaimard, Kiener). The four specimens of this species are of a very dark or black-brown colour, and pale-spotted in the usual way. It is common at the West Indies. PURPURA ASCENSIONIS, Quoy & Gaimard. Hub. Ascension Island (Q. <$f G., Kiener, Kiister, &c). This species has not, I believe, ever been recorded from any other locality than Ascension Island. Two specimens sent by Capt. Turton from St. Helena are in a very worn state, and were obtained by him near the harbour at Jamestown, so, as he observes in his notes, '• perhaps they are not true natives." PURPURA HELENA, Quoy & Gaimard. The specimens obtained by Dr. Conry are not quite like Reeve's type oi fasciata (a synonym of this species), having the tubercles rather more distant, the brown colour of a darker tint, and the blotches within the outer lip much more pronounced ; but this may be due to the fact that none of the specimens appear to be adult. HARPA ROSEA, Lamarck. Ascension Island appears to be a new locality for this shell, which, as far as is at present known, has a limited range on the West Coast of Africa. Kiener cites "les mers du Japon" as the habitat, but this is certainly incorrect. RANELLA COI.LATA, Broderip. Hab. Ascension (Conry). H. pustulosa is a variety of this species. |
