ADAMS : DERBYSHIRE FROM A CONCHOLOGIST's PolNT OF VIEW. 249 



character and south-west aspect is unproductive, perhaps on 

 account of its scanty vegetation. The woods and tors of lovely 

 Dovedale have, as yet not yielded much, though I shall be sur- 

 prised if a summer visit does not reward me. From Winster to 

 x\shbourne by Mappleton is a fine track, after the High Peak 

 railway is crossed, about a mile past which the road descends 

 betAveen some disused quarries and continues with old stone 

 walls on each side, to within two miles of Ashbourne, where 

 hedges take their place. These quarries and walls yielded, 

 amongst other things, white varieties of He/ix hispida, H. coii- 

 cinna, H. rotundala, two specimens of albino Clausilia laininata, 

 and nearer to Ashbourne colonies of Cochlicopa tiidens. The 

 four Arions and Limaces agrestis, arboriim, and Tuaxiinus, with 

 some of their varieties occur throughout the district. 



(3, 4) The Red Marl and Saiidstone Districts. The south- 

 ern district, though enriched in some places by luxuriant vegeta- 

 tion, is a poor one conchologically. One specimen of Vertigo 

 edentula found adhering to the underside of a bracken frond is 

 the most noteworthy capture \ noteworthy because molluscs 

 have a well-known antipathy for bracken, or, at any rate, for the 

 gritty soil on which it flourishes. Round Clifton I have taken 

 occasionally specimens of Zonites excavatus, which, I may re- 

 mark, I have never taken on the limestone. The aquatic 

 species are more numerous in this district than further north, 

 though they are few. 



The fourth or Eastern District I have not worked, and for 

 this I refer to Mr. T. Hey's interesting list in the July number 

 of the Journal of Conchology for 1889.* 



The rivers of Derbyshire are particularly unfruitful. I may 

 mention that I have never taken a single shell in any one, and 



* With reference to Mr. Hey's list, I trust he will pardon me for remind- 

 ing him that the term ' Peak District,' as generally used, applies to the whole 

 of North Derbyshire as far as Buxton. He evidently meant the ' Peak 

 Forest District ' only when speaking of Helix rupestris and H. lapicida.- I 

 am surprised, though much interested to hear that Pupa uinlnlicata occurs 

 near Kinderscout.
