Cyclostoma elegans. Common in the woods at Gloddaeth. 

 In 1877 it was common in the 'Happy Valley' on the 

 Great Orme's Head, but in 1883 I failed to find a single 

 specimen there. 



The list thus includes 35 species and 15 varieties as a con- 

 tribution towards the Denbighshire shell-list. 



Helix villosa Drap. as a British species. — I do not 



consider that this shell should be on the British list at all, as I 

 think that the three or four specimens found on the moor at 

 Cardiff are the only ones that have been found alive. Mr. T. 

 Rogers and I went down to Cardiff the autumn after they were 

 found and searched well for them, but could not find any, but 

 found the exact place where they had been picked up. They 

 had evidently been brought over with ballast, as the moor at 

 Cardiff is the place where all the ballast is put. I have since 

 corresponded with Mr. F. Wotton of Cardiff, and he has seen 

 nothing of it, but he has found living specimens of S. carthagin- 

 iensis, along with dead shells of the same species, and also 

 JI. lactea. Evidently new species discovered at Cardiff are not 

 to be relied upon as British shells. — E. Collier, Manchester. 



Paludina contecta in Yorkshire. — This fine species 

 has been recorded from the immediate vicinity of York, but is 

 now extinct in this locality. During 1883, my friends Mr. W. 

 D. Roebuck and Mr. W. E. Clarke found a dead shell in York- 

 shire, but near to the borders of Lincolnshire. At Askern, a 

 dwarf form in a subfossil state is occasionally turned up along 

 with the soil by the moles. During June, 1884, I found several 

 living specimens in a small tributary of the Derwent between 

 Breighton and Wressle, which again firmly establishes it in the 

 Yorkshire fauna. — Wm. Nelson.-
