 over-sands.

{Concluded frotii page 208). 



Jaminia cylindracea (Da Costa). — A ubiquitous species. It 

 is to be found in abundance under stones on tops of walls, and 

 in some places seems to be very partial to stonecrop. Haggs Lane, 

 Cartmel ; Eggerslack Wood ; Grange Fell Road ; Charney Well 

 Lane ; Windermere Road ; Churchyard wall ; Allithwaite Road ; 

 Cartmel Road; Lindale ; Holme Island and Low Meathop (J.W.J, 

 and C.H.M.), / of C, vol. 11, p. 45; Grange Fell (W.D.R.), 

 / of C, vol. 4, p. 314. 



var. curta Westerlund. — Common ; especially at Cartmel on 

 the walls among stonecrop. Haggs Lane, Cartmel ; Eggerslack 

 Wood (J.W.J, and C.H.M.), /. of C, vol. 11, p. 45. 



var. albina Moquin-Tandon. — This pretty variety existed in 

 two well-established and distinct colonies, almost to the exclusion 

 ot the type ; in fact, not more than ten per cent, of the latter were 

 taken in Hampsfell Road. Here the animals seemed to prefer in 

 dry weather to conceal themselves among the dead dry leaves of 

 laurel, a single leaf sometimes containing five or six specimens ; 

 and in addition, this colony appeared to be absolutely confined to 

 the laurel hedge, as at either end of it not a single shell could 

 be found, either variety or type. On the opposite side of the road, 

 an ivy-covered wall, usually an excellent habitat for this species, 

 seemed to be quite untenanted. The colony at Windermere Road 

 was not so extensive, nor the species so abundant, being confined 

 to a space of about half-a-dozen yards of wall. In this place the 

 wall was quite bare of vegetation (except microscopic lichens), and 

 all the snails were on the garden side of the wall (north), which 

 appeared damper, and was less exposed to the sun and wind. On 

 a dry day not a shell could be seen ; almost without exception 

 the colony consisted of the variety. Hampsfell Road ; Winder- 

 mere Road ; one specimen only at Haggs Lane, Cartmel ; Hospice ; 

 Eggerslack Wood, one shell (J.W.J, and C.H.M.),/. of C.,\o\. 11,

* Jaminia muscorum (Linn^). — Evidently this is one of the 

 rarer species of the district, for it was found in one locality only 

 by the writer, viz. : among stonecrop (Sediun acre), and at the 

 roots of grass tufts growing between the stones, on the top of the 

 churchyard wall. It had for companions H. caperata, P. rupestris, 

 V. pulchella, V. radiatula, and /. cylindracea, and was the
