Twenty-two of these species are wrongly named, namely : -Nos. 8, 

 13, 15. 17. iS) 19. 20, 21, 22, 30, 33, 37, 39, 41, 42, 43, 44, 46 part, 

 48, 52, 56 and 59. Three of them, Nos. 33, 41 and 45 part, are not 

 British species, and nine of the figured shells (Nos. 8, 17, 18, 30, 37, 

 42, 46 part, 52 and 59) although British, appear under names belonging 

 to non-British species. 



Many of these wrong identifications have already been noted by 

 Forbes & Hanley, and Jeffreys in their works on British mollusca, 

 but some are now indicated for the first time, and this has only been 

 possible through an examination of the actual specimens referred to 

 by Pennant. 



Helix nemoralis m. sinistrorsum in West Kent. — Whilst on a conchological 

 excursion with Messrs. R. Welch and A. S. Kennard, to the valley of the Darenth, 

 on October 13th last, I had the good fortune to find a fine adult specimen of the 

 above monstrosity, which, though dead, is in quite fresh condition. The specimen 

 was obtained whilst searching a hedgerow in a lane leading into the Pilgrims' Way, 

 between Otford and Kemsing. The other forms of mollusca noticed at this place 

 were Helix aspersa, Helicella vh-gata, H. caperata var. heripensis, H. cantiana, 

 Hygromia hispida, Helicigona lapicida and Clausilia laminata, — J. Wilfrid 

 Jackson {Read before the Society, Nov. 13th, 1912).
