Il8 JOURNAL OF CONCHOLOGY, VOL. l6, NO. 4, AUGUST, I92O. 



about is to increase the annual subscription from 5/- to 10/- for new members, and 

 to appeal earnestly to present members voluntarily to increase their subscription. 

 In like manner it is proposed to increase the Life Composition Fee from Three 

 Guineas to Six Guineas for future Life Members, and to appeal for increased sup- 

 port from present Life Members. The resolution embodying these proposals was 

 duly advertised and submitted to the members of the Society at a Special Meeting 

 held immediately prior to the present meeting and was carried neni. con. The 

 Council feels confident that sufficient support will be forthcoming to enable the 

 useful work to be carried on, and to maintain the high status of the Journal. 



The Council wishes particularly to point out that authors must be prepared to 

 pay the printers' charges for any alterations made in their proofs. In the case of 

 Reprints, the Council has decided to have them issued in a cheaper form and with- 

 out covers, and authors having illustrations to their papers are invited to contribute 

 towards the cost of printing plates, in addition to paying for the blocks. 



The Library has been fairly M'ell used, and during the past twelve months has 

 received a number of additions, the chief donors being the late Mr. W. Denison 

 Roebuck, Drs. A. E. Boycott, H. A. Pilsbry, P. Bartsch, W. H. Dall, Lieut. - 

 Col. H. H. Godwin-Austen, Messrs. II. Miickardt, A. T. Hopwood, Chr. 

 Petersen, J. A. Grieg, H. O. N. Shaw, J. R. le B. Tomlin, and J. Wilfrid Jackson, 

 In order to economise space in the Journal it has been decided not to publish the 

 various additions in the Proceedings, at least for the present. 



The Autograph Collection has been considerably augmented by a large batch of 

 autograph letters presented by Mr. Hans Schlesch. Other additions were duly 

 noted in the Proceedings of November 13th, 1918. 



The Donations to the Cabinet have been very few, and consist mainly of voucher 

 specimens from the Hon. Recorder. An exceedingly fine collection of slides of 

 Molluscan Raduiss, prepared by the late Rev. Prof H. M. Gwatkin, has also been 

 recently presented by Mr. Joseph Bliss. This addition is very welcome, as the 

 Society did not possess any radulse for purposes of study. The best thanks of the 

 Society have been sent to Mr. Bliss. 



RECORDER'S REPORT. 



Comparatively few fresh records have been added to the Census during the past 

 year. Mr. Roebuck's death in February naturally upset the ordered progress of 

 his organisation, and it is only during the autumn that it has been possible to 

 announce the reduction of the sixty thousand entries which he left in the record 

 books. It is proposed to complete and publish a new edition of the census as 

 quickly as possible, as a memorial to the originator and chief executant of the 

 scheme. 



ANNUAL REPORT OF THE LEEDS BRANCH. 



Eleven meetings have been held, five in the field and six indoors. Four papers 

 have been given. In October last Mr. J. A. Hargreaves gave a paper on "The 

 Origin of the British Marine Mollusca," and in February a second paper on " The 

 Origin of the Freshwater Mollusca." He showed how, by transitionary stages, 

 the evolution from marine to freshwater forms had come about. 



In November Mr. F. Rhodes gave a paper on " Evolution in Mollusca." He 

 confined his remarks to the lower forms, and showed the great similarity in the 

 early stages of development in certain mollusca, the Brachiopoda, and worms.
