CLAUSILIA KOLPniI. 249 



for August,'|1854. I beg to assure you, nevertheless, that the statement 

 referred to is perfectly accurate, and that within a fortnight of Mr. Guise's 

 visit to Birdlip in April, 1857, I also revisited that place, after an absence 

 of more than three years, and remained till the end of May, and during 

 that period never experienced any difficulty in procuring at least "twenty 

 specimens" of Clausilia Rolphii in an hour's search, exactly in the spot 

 indicated; besides numerous specimens of all the shells mentioned by him, 

 as found during his day's ramble, including also Azeca tridens } which was 

 equally numerous with G. Rolphii. 



As I had previously heard from the gentleman alluded to, as connected 

 with the British Museum, that his search had been unsuccessful, I forwarded 

 for his acceptance a box containing about a dozen living specimens, taken 

 fresh the morning on which they were sent; but as I never received any 

 acknowledgment, I presume the package must have miscarried. 



I have the pleasure of enclosing for your acceptance, several specimens 

 of the identical shells taken by me in May last, if they will be of the 

 slightest service to you, and I shall also be most happy to forward a 

 series to Mr. Guise, if he will favour me with his address in full. 



G. Rolphii appears to me to be gregarious, and is certainly very local, 

 but I cannot conceive how either of the gentlemen failed to find it, as 

 the marks made by Mr. Guise's search amongst the Chrysosplenium were 

 perfectly visible, precisely in the spot where I took so many only a few 

 days later. I also met with the same shells in equal numbers near the 

 park wall in the same wood, but there also confined to a small space; 

 indeed with my little children's assistance, I procured upwards of sixty 

 specimens there, in a very short period. Later in the same year, (1854,) 

 I found G. Rolphii about a mile from Southborough, near Tunbridge Wells, 

 and also near Petersfield, in Hampshire, in company with Helix obvoluta. 



Bulimus lachamensis, abounds in the Birdlip Woods during spring, though 

 it is difficult to procure later in the season: I met with one specimen 

 with reversed volutions. The white variety of Clausilia bidens is also by 

 no means unfrequent. 



It may interest some of your readers to know, that during July last 

 I had the pleasure of taking, near Bowness, Windermere, several specimens 

 of Vertigo alpestris, evidently quite a distinct shell from V. pygmoea, also 

 V. sexdentata and Helix lamellata; the latter I also procured at Castle- 

 head, Keswick; and in the wood's of Bonshaw and Springkell, Dumfriesshire. 



Before leaving Birdlip I pointed out the exact spot to Mr. Pinching, 

 the landlord of the Black Horse, that he might be able to indicate it to 

 any visitor interested in the subject, so that should Mr. Guise or his 

 friend again visit Birdlip, I feel assured that they will be rewarded by 

 success, indeed I had a letter from a gentleman about a month since, to
