ward range of various species and the influence of environment thereupon, has 

 commenced a series of papers in the "Scottish Naturalist" upon the more neglected 

 vice-counties of Northern Britain. The first paper on Easterness appeared in May, 

 and the second on Main Argyll in September, while a third on Wigtownshire 

 appeared in the October and November numbers. 



ANNUAL REPORT OF THE LEEDS BRANCH. 



We have had ten meetings during the year : — Four in the field, viz., at Heckmond- 

 wike in April ; at Woodlesford in May ; at Adel near Leeds in July ; and at South 

 Milford in September. No new species were added during the year, but our 

 knowledge of the distribution of species is being extended. 



Of the six indoor meetings, three were held in the University, Leeds, and three 

 in the Cartwright Hall, Bradford. These winter meetings continue to attract an 

 excellent attendance, with an average of thirteen members. Two of the meetings 

 were devoted to a display of Clausilia and Balea respectively, and Mr. J. W. Taylor, 

 M.Sc, gave a survey of the characteristics of the types and varieties, their bio- 

 logical peculiarities, and their distribution. As in the past, the members are 

 greatly indebted to Mr. Taylor for the knowledge gained through his addresses. 

 Mr. A. Hartley gave a paper on Achatinellidce, illustrated by a fine display of 

 specimens, and by numerous photographs of scenery, showing the varied habitats 

 of this beautiful family in the Sandwich Isles. Mr. J. A. Hargreaves gave a 

 practical paper on the Marine MoUusca of the Yorkshire coast, illustrated with 

 specimens. He fully explained the methods of collecting, the habitats of particular 

 species, and how to look for them. Both papers were most instructive. 



Our membership is the same as last year — 23, with three corresponding mem- 

 bers. Mr. Greevz Fysher is our President. -p gQQ.r.TT tt ., o 



ANNUAL REPORT OF THE LONDON BRANCH. 



Only six meetings have been held during the past year. The war has claimed the 

 whole time of several members, and most of the others have had little leisure for 

 shells ; consequently the attendance at all the meetings has been small. 



Field-meetings were held at Mitcham, Swanley, and Putney, but nothing worth 

 recording was collected. 



At the evening meetings various interesting shells were exhibited, especially 

 Hygromia icinbrosa from Margate (already noted in the /omnal of Conchology, vol. 

 XV., p. 11), and Cassidaria rugosa from the Irish Sea. 



We are again indebted to Mr. J. C. Dacie for giving us house-room for the 



evening meetings. t -c r^ tt
