Drew's Pond, Devizes (Vize) ; Stourton, Edington, and Amesbury 

 (E. W. S.). 



In all probability the last four species have a much wider distri- 

 bution than the above records indicate. 



Species Erroneously Eecorded for Wilts. 



The H cartusiana in the Cunnington Collection at Devizes are 

 H. cantiana. Bulimus ventrosus (= Helix acuta) in Bromehead's 

 list of shells from the neighbourhood of Marlborough should have 

 been Cochlicopa lubrica. 



Addenda. 



Since the foregoing notes were published in the Journal of 

 ■Conchology I have received the following interesting communication 

 irom Dr. H. P. Blackmore, of Salisbury : — 



" You may like to hear that Helix cantiana occurs at two spots 

 close to Salisbury. I fancy this species has been brought from 

 Weyhill Fair, both localities are by roadsides, where flocks of sheep 

 pass from Andover. Testacella haliotidea also occurs here — it was 

 first noticed on the site of an old nursery garden, so it was probably 

 introduced in the soil with plants. Some years ago I turned out 

 three in the garden at the back of my house, and this year I find 

 they have increased considerably, and are not difficult to find if 

 hunted for with a lantern at night. 



" The best evidence of Helix aspersa being indigenous to England 

 occurred at Dewlish, in Dorset, in 1898. When examining the 

 Pliocene gravel of this locality I accidentally came upon an un- 

 disturbed bed of sand 4 or 5 feet in thickness of Holocene age. 

 This sand contained a large number of land shells, amongst them 

 nine examples of Helix aspersa. 



" Succinea oblonga can no longer be reckoned as foreign to this 

 district. I met with it at Alderbury in a damp gravel pit in 

 1890, and have since occasionally seen it in the same place, but it 

 is not abundant there."
