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.

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
