258 MR. E. A. SMITH ON THE [Apr. 5, ser. 2, vi. p. 19) to the Hartebeest of South Africa (Bubalis caama) , but that it was evident, from the shape of the horns and colour of the hairs, that this specimen also belonged to B. swaynei. In reference to some remarks that had been made upon his usage of " Bubalis" instead of " Alcelaphus " for this group of Antelopes, Mr. Sclater pointed out that " Bubalis " of Lichtenstein was pro-posed in 1814 (Mag. d. Gesellsch. nat. Fr. vi, p. 152), two years hehre '•' AlcelapJius " of Blainville, and had been constantly used by Sundevall, Peters, and other writers, so that it had undoubtedly good claims to priority. A note was read from Professor Jeffrey Bell regarding the habitat of Bipalium kewense. This interesting Planarian, first found in Kew Gardens, had been observed in very various parts of the world. In only one case, however, did the circumstances of its discovery make it possible that the worm was indigenous to the place v^here it was met with. That one place was Samoa, where Mr. J. J. Lister found it uuder stones in the bush. Mr. Fletcher, in communicating this fact to the Linnean Society of New South Wales (see Zool. Anzeig. 1891, p. 139), had expressed the opinion that there was little ground for supposing that the species was indigenous in Samoa. Further reason, however, for supposing that Samoa may be one of the places in w^iich the worm is indigenous was to be found in the fact that Mr. R. B. Leefe had recently collected the same worm in Tongatabu. Prof. Bell had learnt from the Director of the Royal Gardens, Kew, that though no plants had, to the Director's know-ledge, been received directly from Tongatabu, exchanges had been made with Fiji. It might be urged that the probability of the group of islands just named being the original home of the species was, on the whole, increased by the facts now stated. The following papers were read : — 1. On the Laud-Shells of St. Helena. By Edgar A. Smith. (Plates XXI. & XXII.) [Eeceived March 2, 1892.] Last year I had the honour of presenting to the Society an account of the marine Mollusca of St. Helena. I now propose to introduce to its notice some remarks upon the terrestrial fauna of that island. Like the former, the present report is based chiefly upon collections made by Capt. W. H. Turton, R.E., and presented to the British Museum. The collection is the most complete that has ever been made, and contains examples not only of most of the known species, but also of as many as eleven undescribed forms, a proportion of more than one third of the entire fauna. Our best thanks are due to Capt. Turton for the labour of getting together such an interesting
