30 JOURNAI. OF CONCHOI.OGY, VOL. I3, NO. I, JANUARY, I9IO. 



It is perhaps not out of place to offer a suggestion, that, when the total number 

 of authentications reaches the round figure of 10,000, which it will in all probability 

 do within the next few months, the journal of Conchology should print either a new 

 "Census or a table of the blanks yet to be filled up. 



Meanwhile, it is much to be desired that special attention be paid to the working 

 out of Scotland, for which there have been only 65 new records during the year. 

 This portion of the kingdom is especially interesting in respect of the thinning out 

 of our fauna as we go northward, and the interesting problems of geological and 

 climatological influences and their effect on distribution. The greatest difficulty 

 has been experienced in obtaining Scottish material or informations, doubtless in 

 part attributable to the fact that Scottish malacologists are but few in number and 

 widely scattered, which makes it needful ihat a special effort be made during the 

 coming season to work up this portion of our islands. Therefore the Recorder would 

 be glad if all conchologists who have Scottish material in their possession, or who 

 would volunteer to assist by making Scotland the scene of investigation, would 

 place themselves in communication with him. 



A few remarks on the blanks for certain generally distributed species may be of 

 interest. 



Agriolimax agrestis is still needed from Carmarthenshire only. 



Arion ater is needed from Sussex East, Ross W. and E., and Longford. 



Vitrhia pdliuida is needed from Wilts. N., Hants. N., Aberdeen N., Ebudes S., 

 Shetlands, Longford and Mayo E. 



Hyalinia cellaria is needed from Aberdeen N., Westerness, Sutherland W., 

 and Longford. 



Pyra7nidula roHindata is still needed from Aberdeen N. and Longford. 



Cochlicopa lubrica is needed from Linlithgow, Aberdeen N. , Banff, Elgin, 

 Ebudes S., Longford and Roscommon. 



REPORT OF THE LEEDS BRANCH 



For the Twenty-One Months ending September, 1909. 



Our report in the past has been the Annual Report of the Branch, issued in 

 December of each year. The Annual Meeting of the parent Society being held in 

 October, we have given our report to the end of the previous December, which, 

 in the opinion of the Editor of the journal, is a little antiquated. 



On his suggestion, we have this year brought our report up to modern times by 

 giving the particulars up to the end of September, 1909, which covers twenty-one 

 months instead of twelve. During this period we have had twenty-four meetings 

 — fourteen in the field and ten indoors — with an average attendance of six mem- 

 bers, exclusive of visitors. 



The indoor meetings were held alternately at Leeds, in the Institute of Science 

 and Art ; and at Bradford, in the Cartwright Hall. Our field meetings were held 

 in the neighbourhood of the following places : — 9th May, 1908, Agbrigg, for the 

 Barnsley Canal ; 27th June, 1908, Keighley, for the old river bed and a visit to the 

 Museum ; l8th July, 1908, Malham Tarn ; 15th August, 1908, Micklefield 

 and Aberford ; 12th September, 1908, Ingleton (Joint Annual Ramble with the 

 members from Manchester); I2ih April, 1909, Southport ; 8th May, 1909, Market
