promises me to watch the stones at the foot of the lime-kiln, and inform me if any 

 fresh crop of capsules is produced. What he has sent me are small and green ; 

 yet some of them had sufficiently exhibited the twisted stmcture to characterise the 

 species independent of the foliage ; and though they are not so numerous as I 

 could wish, you must consider (as I do) half of them as your own. 



2,yd yovejube?-, 1832. 

 I was in Derbyshire the end of last April, I found from twenty to thirty 

 capsules of Encalypta streptocarpa in an unripe state on the two lumps of tufa 

 under the old lime-kiln in Lathkil Dale on which I found them last year, but not 

 one on the new piece you rolled there. I left them in charge of Mr. Henry 

 Bowman, but they had made no progress at Midsummer when my daughter was 

 there. She brought me a few, and left the rest to their fate. I also found about 

 six more capsules near the top of the wall close to the Conksbury Bridge, but not 

 one lower down the wall and nearer the water, though the moss was there 

 unusually abundant and luxuriant. From this I infer that the very moist atmos- 

 phere and the partial seclusion from light and circulation of air is not favourable 

 to its fructification. I visited Rowter, and replenished my stock of Schistostega, 

 Didymodon {Cynodcntium) bniiiioni, etc., and got a few more capsules of Weissia 

 \Seligeria) pusilla^ but do not recollect anything else that was interesting. 



24^'/^ October, 1833. 



I spent about a fortnight in Derbyshire in August, whither Mrs. Bowman 

 accompanied me, and being with friends and the weather very unsettled, I could 

 not devote much time to botany, Mr. H. Bowman had gathered for me in May 

 about a dozen capsules of Encalypta streptocarpa^ which, like the former, had not 

 ripened kindly ; but there was none on the piece of tufa you had rolled under the 



lime-kiln I saw abundance of Hypmtm riigosum in Dovedale, but all 



barren ; and gathered MentJia rubra, M. viridis, and M. piperita, and what I 

 suppose will prove a hairy variety of M. rubra ; Verbascum nigrujn, Polenionium 

 caruleum, Galeopsis ladaiium, and a species of Cardials, which I shall believe to 

 be new to our Flora till I am told to the contrary either by yourself or some other 



competent botanist wSoon after our return out of Derbyshire we went into 



Wales. At the upper end of Llanberis lower lake I found a solitary clump of 

 Mentha rottmdifolia, and on the margin of Capel Curig lower lake noble specimens 

 of Cajupanula hederacea, both in flower and fruit. 



NOTE— CONCHOLOG V. 



MoUusea of Coniston and Carnforth, Lancashire. — On 



April 6th I had two hours at Carnforth, and met with the following species of 

 Mollusca : — Lifnax agrestis, Vitrina pellucida, Zoiiites cellarius, Z. radiatulus, 

 Z. purus. Helix aspersa, H. nernoralis, H. aculeata, H. eruetorum, H. rttfescens, 

 H. piilchella, H. rotundata, H. rupestris, Bulitnus obscurus, Cochlicopa iubrica. 

 Pupa u?nbilicata, Vertigo edentula, Clausilia riigosa, and vars. dubia and tutuidula. 

 One each of H. rufescens and Vitrina pellucida showed traces of spiral banding. 

 The greater number of the above occurred on the summit of the limestone hill 

 called W^arton Crag. It may be interesting to note that all the Clausilia 7'ugosa 

 on this hill belonged to the var. dubia, while all those in the valley were typical. 

 I should like to know whether the var. dubia is ever found in other than elevated 

 localities. 



On the following days I took several species near Coniston. Valvata piscinalis, 

 Physa fontinalis, and LitnncEa peregra var. lacustris are fairly abundant in the 

 Lake, and Ancylus Jiuviatilis occurs in most of the larger streams. Arion ater 

 and a fine example of var. albolateralis (is this not also an inhabitant of hilly 

 districts?), A. bourgtdgnati, Limax agrestis, L. loevis, and Z. arborum were the 

 slugs seen. The land-shells were V, pellucida, Zntiites alliarius, Z. nitidulus, 

 Z. radiatulus, Z. excavatus, Z. fulvus, Z, crystallinus, H. aspersa, H. nemoralis, 

 H. hispida, H. rotjitidata. Pupa umbilicata, Clausilia rugosa, and Cochlicopa 

 lubrica. I happened to put two living Z. peregra in a box with the slugs, and 

 found, on looking at them the next day, that they had been entirely devoured, 

 leaving the shells clean and empty! — S. C. Cockerell, Bedford Park,W., April 24.
