R. STANDEN : LAND AND FRESHWATER MOLLUSCA. 



' Much less common than the preceding species. Gardens at 

 Didsbury, Chorlton-cum-Hardy, etc. Rarely seen after mid- 

 summer ' (Hardy's List, 1865). 

 Amalia gagates Drap. Common in a garden at Swinton. A few 

 specimens taken at foot of walls at Southport, and Ashton-on- 

 Ribble. 



Limax maximus L. Common at Swinton. But few met with about 

 Preston. 



Limax flavus L. Occasionally met with about Preston and Swinton. 

 Limax agrestis L. Very common everywhere. 

 Limax arborum B.Ch. 



' Northenden Lane, Didsbury, in a belt of wood, i860' 

 (Hardy's List). 



One specimen in a cellar at Greenheys, 1841-6 ' (R.D.D.). 



Mr. Heathcote has taken some splendid specimens of Zonites 

 draparnaldi in his greenhouse at Preston, and I have taken one 

 fine shell in my own fernery, which may have come in some 

 foreign ferns sent to me by him, and it is probable all are im- 

 portations. Splicerium laciistre^ Paludma cojitecta^ Byth. tenia- 

 culata, Planorbis cartnatus, Planorbis complanatiis^ Planorhis 

 corners, Limncea siagnalis^ and Li?n?icsa glabra have been intro- 

 duced by Mr. Heathcote in quiet ponds about Farrington, from 

 localities near Manchester which seem doomed to destruction 

 at no distant period. All these are increasing rapidly in their 

 new homes, and may even now be termed abundant. Helix 

 pisana has been planted in considerable numbers in seemingly 

 favourable situations, amongst the Southport sand-hills, by 

 Mr. Heathcote. Mr. T. Rogers tells me he has often tried to 

 colonise it, but has hitherto failed, owing, he considers, to birds 

 preying upon it. 



Note : — Hough-end-Clough (' ouse-end-clough ') was (alas !) a 

 lovely little woody water-course, cut down below the flat of the 

 surrounding country south of the town, full of plants, insects, and 

 molluscs. 



In Dyson's List, and Hardy's, Chorlton means Chorlton-cum- 

 Hardy, a township abutting on the north side of the Mersey. Since 

 i860, most of the waters hereabouts have been dyed and poisoned, 

 and most of the grass and hedge-backings have been seriously 

 poisoned by smoky rain, and have been sadly less congenial to 

 plants, insects, and shells. \\\ 184 1-6, I searched all this southern 

 district very well ; and again about i860. I think the ponds had 

 become much less pure and fruitful (R.D.D.).
