seen about eight or nine examples altogether, barely differing, except 

 in size. The above measurement was taken from the largest obtained. 

 I do not think it can be compared with L. piiUeinei Yerco, the shells 

 are so abundantly distinct. Both were described within a very few 

 months of each other. 



It only remains for me to thank the Editor of Proc. Malac. Soc, 

 Lond., for having kindly lent the process blocks, belonging to the 

 Society, of L. ernesti and soiverbyi, for the purpose of reintroduction 

 into this paper. I only wish it had been possible to illustrate all the 

 species, but in every instance references have been given to the 

 original figures. : , 



Note on Helix Pomatia. — -I have a couple of captive Helix pomatia wliich 

 are kept in a wooden box. At the Ijottom is a sod on which, of course, the grass 

 lias 1)}' this time died oft'. On looking into the box a few days ago, I find that all 

 the dead grass has been collected and formed into a heap in one corner under which 

 the snails are now hil^ernating. (One has formed the usual epiphragm, the other 

 has not). Query : What method is adopted in the collecting and transporting of 

 the grass?— Geo. C. Spencr (A'i?rtc^/;4/tfi;-£ z'//« i'(?aV/;)', Jan. nth, 1911). 



Limnsea pereger v. lacustris Leach living without shell. — Whilst collecting 

 specimens of tliis species in Derwentwater last summer, I was surprised to come 

 across two specimens quite shell -less. They were crawling upon the stony bottom 

 of the lake in about one foot of water.— W. Gyngeli. {Read before the Society, 

 Jan. nth, ign). 



An Interesting Association of Species in Windermere. — In June, 1910, 

 where the lake washes the shore of what is called the Colgarth estate, a mile or so 

 north of Bowness, I found the following species on the shingle bed which forms the 

 margin of the lake, and in some two or three feet of water, all within fifty yards 

 length of the shore. Livimea ptreger var. lacustris, L. pahistris (a short and 

 decollate form), Flanorbis albus, Physa fontinalis, Ancylus jlnviatili^ (fine speci- 

 mens including type-colour and var. albida, the latter being quite common), and 

 Spheriwn corneiaii v. Jlavesccn-s. The Planorbis is generally regarded as inhabiting 

 slow-running streams and stagnant water ; I have, however, found it crawling' on 

 and under the stones of one of our swift-running Yorkshire moorland streams.— 

 W. Gyngeli, [Kead before the Society, ]a.v\. nth, ign). 



Helix aspersa m. sinistrorsum at Scarborough. — To the records of sinistral 

 monstrosities I have pleasure in adding a full-grown and perfect example of the 

 above, found by myself thisautumn on the Castle Hill, Scarborough, —W. G'N'N'i'.f.i.i, 

 {A'ead be/oir tlif SPiie/y. \-AX\. \\\\\. iQn).
