Yorkshire Naluralisfs' Union : Annual Report, 1909, 55 



^Members of the Committee are requested to send difficult 

 specimens to Mr. Falconer for identification, and labels giving full 

 data should be inserted in the tubes of spiders, etc., sent to him. 



]\Ir. W. P. Winter makes an excellent suggestion with regard 

 to one phase of the work which might be taken up by the new Arach- 

 nological Committee, viz., that members should as far as possible 

 work up by Photomicrographs the essential organs and general 

 structure of certain selected genera. Copies of photographs made 

 could be exchanged amongst arachnologists in the county, and 

 would prove of great ser\-ice in tiie identification of species. 

 There is also much good work to be done in taking observations 

 of the habits of rarer species. Entomologists working in the 

 remoter parts of the county could render great assfstance if the}- 

 would collect any spiders they might meet with, and forward them 

 to some member of the Committee. 



The Committee for iqio is as follows : — 



Chairman — W. Falconer, Slaithwaite. 



Convener — T. Stainforth, Hull. 



Representative on Executive — T. Stainforth, Hull. 



Representative on Committee of Suggestions— T. Stainforth, 

 Hull. 



Other Members— W. H. ^^'inter, B.Sc, Shipley; W. J. Ford- 

 ham, M.B., Selby ; H. C. Drake, Scarborough; W. 

 Denison Roebuck, Leeds; G. B. Walsh, B.Sc, 

 Middlesbrough ; and E. A. Parsons, Hull. 



CONCHOLOGICAL SECTION. 



In so well-worked a subject as the Land and Fresh-water 

 Mollusca of Yorkshire, it can hardly be expected to find novelties, 

 and the work done is chiefly concerned with detailed local dis- 

 tribution. \\'ork of this kind has been done at all the excursions 

 of the Union, Messrs. Hutton, Musham, Roebuck and Taylor 

 being present at Market Weighton, Messrs. Saimders and Woods 

 at Runswick, Mr. Musham at Sedbergh, and Messrs. Crowther 

 and Hutton at Cawthorne, while at Bowland shells were collected 

 by Mr. R. P'owler-Jones. No species calls for special comment, 

 except that Milax sowerhyi, so unaccountably rare in Yorkshire, 

 though an unmitigated pest in some localities in the south, has 

 been found at Cawthorne and in Leeds, each case being a new 

 vice-comital record. In respect of marine mollusca, Mr. Saunders 

 and Rev. F. H. Woods collected specimens at the Runswick 

 excursion. 



The Section has met monthly throughout the year in friendly 

 co-operation with the Leeds Conchological Club, to mutual advan- 

 tage. 



Of work done, attention may be called to the appearance of a 

 new part of Mr. J. W^ Taylor's magnificent Monograph, and also 

 to Mr. J. A. Hargreave's list of Scarborough mollusca, and Mr.
