56 Yorkshire Naturalists' Union: Annual Report, 1909. 



J. W. Jackson's paper on Holocene Mollusca near Great Mytton 

 in Bowland, both printed in the " Journal of Conchology," and 

 it is a pity that these papers should not have appeared in our own 

 journal " The Naturalist." 



East Yorks., Mr. J. F. Musham writes : — Although the 

 climatic conditions have been adverse throughout the greater 

 part of the year for genial field days, it appears to have been 

 very favourable to Mollusca, in spite of the more or less swollen 

 state of dykes and streams, which interfered somewhat with 

 search for aquatic species. 



The first Field Meeting of the Union was held in this division 

 at Market Weighton, on Saturday, May 8th. Although the 

 weather was cold and dry, the conchologists were in full force, 

 and upwards of forty species of Mollusca were noted. 



Acanthinula aciileata Miill. was wanted, to add to the list of 

 East Yorkshire shells, but no one was lucky enough to turn it up. 

 Mr. A. J. Moore reports that Milax soiverhyi var. nigrescens Roeb. 

 and Milax gagates vslv. rava have been taken at Hessle and Hull 

 respectively ; also Helix rufescens vars. alba Mog. and ruhens have 

 occurred at Hessle, and Helix cantiana var. rubescens at Kelsey 

 Hill, Holderness. 



These, with Planorbis nautileiis var. inibricata, which I dredged 

 up at Bowthorpe, October 2nd, are varieties not recorded in 

 Fetch's " List of Land and Fresh Water Shells for the East 

 Riding," and are welcome additions to the divisional list. 



The Officers were elected for 1910 as follows : — 

 President — John F. Musham, Selby. 

 Secretaries — W. Denison Roebuck, Leeds ; Thos. W. Saunders, 



Brotton; A. J. Moore, Hull. 

 Representative on Executive — J. E. Crowther, Elland. 

 Representative on Committee of Suggestions — W. Harrison 

 Hutton, Leeds. 



Marine Biology Committee. — The Rev. F. H. Woods writes : — 

 A very important meeting of the Marine Biological Committee took 

 place at Leeds, on Satiu'day, February 13th, in connection with 

 the Leeds Conchological Society, in which we had the pleasure of 

 welcoming for the first time, our new Chairman, Professor Gar- 

 stang, who made some valuable suggestions as to the future work 

 of members interested in the subject. He urged upon them to 

 observe very attentively, and record, the habits of marine animals 

 of every sort ; facts even that seemed trivial might prove veiy 

 important. What was especially interesting was the promises he 

 held out for the future, of giving active support to the work of 

 the Committee. In particular he expressed a hope of being able 

 to arrange a meeting on some part of the coast. This hope, un- 

 fortunately, has not yet been fulfilled, but it will be, let us trust, in 

 the course of next year. 



The only coast excursion in 1909 was that at Runswick Bay.
