MILNE AND OLDHAM : MOLLUSCA OF BOWDON DISTRICT. 317 



L. flavus. In nursery gardens at Sale. 



L. arborum. Mere Park ; once from a garden at Bowdon. 



Agriolimax agrestis. Common everywhere; more nu- 

 merous individually than Avion hoitensis, and much 

 oftener seen, as the least dampness brings it out to activity 

 in the daytime. 



A. agrestis var. tristis. Bowdon, Sale, Northenden. 



A. agrestis var. sylvatica. Almost as common as the type 

 form, but not often found with it. As a rule, the speci- 

 mens from one locality are fairly constant in colour and 

 markings. 



A. Isevis. Used to be plentiful at Ashley Hall, in the marshiest 

 part of the copse ; still found at Butt's Clough. 



Testacella scutulum. Mr. Thomas Rogers has specimens 

 from nursery gardens at Sale. 



Vitrina pellucida. Plentiful in a few localities— at Gatley, 

 Wythenshawe, Ashley Hall, and in the copses by the BoUin 

 at Castle Mill, Butt's Clough, and Ashley Mill. 



Hyalinia cellaria. Universally distributed through the 

 district. 



H. alliaria. If possible, commoner than H. cellaria, as it 

 displays a greater love for fields and unsheltered places, 

 probably protected by its smaller size and darker colour. 



H. alliaria var. viridula. Occurs occasionally with the type. 

 We have found it at Bowdon, Ringway, Ashley Hall, and 

 Lymm. 



H. nitidula. Almost equally common with the last two. 



H. radiatula. Rather scarce. It has been taken in small 

 numbers at Ashley Hall, Butt's Clough, Hale, Bollington, 

 and Baguley Hall. 



H. pura. Plentiful where it occurs — at Ashley Hall, Wythen- 

 shawe, and Baguley Hall. The prevailing form is the white 

 one (v. margaritacea Jeff = type Alder), only in the last 

 locality is the brown variety ( = type Jeff.) found with the 

 other.
