NOTES — MOLLUSCA AND BOTANY. 



It will be seen, on examination of the foregoing list, that the 

 most important and significant fact it contains is the discovery of 

 Clausilia rolphii^ important inasmuch as this new district for it is so 

 far distant from the very few English counties which the species has 

 hitherto been known to inhabit and much further North tlian any 

 one of them, and significant as showing the possibilities of a county 

 which has been so little worked as, Lincolnshire. 



Since the appearance of the first portion of the list, specimens 

 and information have been sent me by the Misses Laura and 

 Katherine Mason, Messrs. J. Darker Butterell, J. W. Carter, J. Burtt 

 Davy, and J. A. Hargreaves ; and Mr. George Roberts has done me 

 the inestimable service of pointing out the existence of a list of North 

 Lincolnshire Shells which, from having been published so long ago 

 as 1864 in a very obscure journal, had quite escaped my researches. 



It seems best, however, to let this paper stand as originally 

 written, and to embody the additional facts thus brought to light 

 in a supplementary paper, which I hope to issue in an early number, 

 and in the preparation of which I trust that any readers who have 

 specimens or information of any kind not included in the paper will 

 kindly assist. 



NOTES— MOLL USCA. 

 Pisidium roseum in Yorkshire. — A specimen of this species was 



sent to me about a year ago by Mr. W. A. Gain, who had found it in the rejecta- 

 menta of a small stream near Bawtry, in the spring of 1886. The only previous 

 Yorkshire record was for Bentley, near Doncaster. — John W. Taylor, Leeds. 



Helix arbustorum monst. sinistrorsum in Derbyshire.— 



When collecting H. arbiistoriini and its variety flavescens among nettles by the 

 road-side in Ashwood Dale, near Buxton, on the 1st inst., I found a sinistral 

 monstrosity of the variety, and as I believe this form of H. arbustorum has not 

 been previously recorded for Great Britain, a note of my capture may be of interest 

 to some of your readers. The typical form of the species and the var. flavescens 

 were present in about equal numbers. — Chas. Oldham, Sale, 5th August, 1S87. 



NOTE— BOTANY. 

 Chara fragilis var. f ulcrata in Yorkshire.— In the stagnant pool 



of an old stone quarry at Sandal near Wakefield, I noticed in July last year, a fine 

 fruiting Chara, which was evidently Chara fragilis Desv. , but not typical. Acting 

 as distributor in the early part of the present year for the Watson Botanical 

 Exchange Club, I sent specimens to Mr. Arthur Bennett, F.L.S., of Croydon, the 

 Referee for the Club, and he places the plant under Chara fragilis Desv. var. 

 fidcrata Gant., a form not contained in Messrs. H. and J. Groves' revised list of 

 the Charace(F, in the 8th Edition of the London Catalogue (1886), though it is 

 fully set forth in their 'Review of the British Characese' in the 'Journal of 

 Botany' for 1880 as characterised by very short bract -cells, and rudimentary 

 stipulodes. Chara fragilis and its various forms are monoecious plants, the var. 

 fnlcrata 'resembling the fertile plant of C, connivens,'' a dioecious Chara. — 

 P. Fox Lee, Dewsbury, August 6th, 1887.
