R. Cantiana, H. virgata (two vars.), and a dark S. aspersa are very 

 abundant. I fonnd no H. Carthusiana. 



The first section is at right angles to the new road, and runs with 

 the slope of the hill : it exposes a hill-wash of a remarkable character. 



At the lower part Helix aspersa was exceedingly plentiful, from the 

 youngest and most fragile shell to the massive adult specimen. Near 

 the base of this deposit occurred a fragment of Roman tile. "When 

 these shells were living on the spot the flints must have been on the 

 surface, for even the youngest shells are quite uninjured. 



In this deposit occur : 



Vitrea cellaria, Miill. 

 ,, nitidula, Drap. 

 Pyramidula rotundata, Miill. 

 Helicella Itala, Linn. 



,, caperata, Mont. 



,, Cantiana, Mont. 



,, Carthusiana, Miill. 

 Sygromia hispida, Linn. 



,, rufescens, Penn. 



Vallonia pulchella, Miill. (1 specimen). 

 Helix aspersa, Miill. 



,, nemoralis, Linn. 

 Cochlicopa lubrica. 



Pupa muscorum, Linn. (1 specimen). 

 Clausilia laminaia, Mont. (1 specimen). 



About 150 yards eastward another promontory has been cut away 

 to form the road. Here for about 100 yards the face of the section 

 may be generalized as follows : —
