LONDON BRANCH— Annual Report. 



During the past year there have been thirteen meetings of this branch, seven of 

 which were field meetings. The attendance at most was somewhat disappointing. 

 As we have had a very dry summer it has been almost impossible to collect land 

 shells ; freshwater collecting was fairly successful. Messrs. J. C. Dacie, A. S. 

 Poore, J. B. Rosevear, and W. M. Webb, F.Z.S., kindly invited us to see their 

 collections on various dates during the past winter ; we are also indebted to Dr. 

 Tuke, of Chiswick, for permission to visit his grounds. Our president, Rev. J. W. 

 Horsley, brought his annual consignment of living Swiss mollasca to the June meet- 

 ing. The membership of this branch is about the same as it was a year ago.

LEEDS BRANCH— Annual Report. 



The last Annual Meeting was held at Crossgates, on the 22nd April, 1898, when 

 Mr. H. Crowther, F.R.M.S., was elected President, and the two Hon. Secretaries, 

 Mr. W. Denison Roebuck, F.L.S., and Mr. W. Nelson, were re-elected. 



The papers read have been more numerous than during the preceding year, and 

 several of them have been printed in The Naturalist. The papers so published 

 include two by Mr. Nelson, in which he described visits to Wiston and Cawood, 

 and to Camblesforth and Gowdall in search of Limncea glabra. Also a short paper 

 by Mr. J. Hawkins on "Food as Influencing Variation in Helices," communicated 

 through Mr. J. W. Taylor, F.L.S. A short paper by the President "On the 

 Bionomics of the Mollusca inhabiting the Scar at Whitby," and a brief note by 

 him on the "Occurrence of Planorbis cornetis in flood-refuse at Skipton." Two 

 papers dealing with subjects beyond the geographical scope of The Naturalist have 

 been printed at length in the Weekly Supplement of the Leeds Mercury. In one of 

 these Mr. Nelson recounted "A Conchological Pilgrimage to Loch Skene in search 

 of Limncea bnrnetti" and in the other the President gave an account of Mr. 

 Moore's investigations of the peculiar molluscan fauna of Lake Tanganyika. 



Of papers and addresses not intended for publication, Mr. J. W. Taylor, F.L.S., 

 gave an account of the classification of molluscan teeth. Mr. Cash, F.G.S., gave an 

 account of the distribution and variation of the Achatinelke of the Sandwich Islands ; 

 and Mr. Broadhead initiated an interesting discussion of some points in evolution, 

 more especially as bearing on the mollusca. The exhibits have been very numerous 

 at all the meetings, and of much value and interest. 



On the whole the Club is to be congratulated upon the sound and satisfactory 

 position which it now occupies, as well as upon the success of the quiet and unas- 

 suming work done by its members.
