 Caton, or rather, the old village Brookhouse, a lane near the church ; 

 at intervals to Claughton ; Hornby (G. Roberts, Journ. of Conch., 

 vol. 3, p. 255); Bolton-le-Sands (H. Beeston) ; Hale Moss, Burton-

var. fusca Ferussac. — Kirkby Lonsdale (E. Collier), 1888. The 

 type occurs near the Devil's Bridge, and this variety on the waste 

 ground near the Lune. 



Helix aspersa Miiller. — Well distributed, but somewhat local. 

 The general type is a dark shell, approaching in some cases to 

 nigrescens, but more often to albo-fasciata or flamniea. Hibernation 

 continues to the end of April or the beginning of May. On May 3rd 

 this year the thermometer dropped to 51 deg., and on ]\Iay 5th rose 

 to 61 deg. On May 7th seventy snails were counted at the base of a 

 wall near Hest Bank, and all were engaged in copulation with the 

 exception of a few with an unformed lip. Many had the remains of 

 the freshly-broken epiphragm attached to the shells. Lancaster ;

 mate percentage as they occur in the Lancaster area : —
