ftreaked with brown or chefnut, which at the bafe fre- 

 quently become confluent, and form one or two regular 

 bands : aperture fub-oval ; outer lip thin ; pillar lip a 

 little reflexed, forming a fmall cavity behind. Length 

 near three-quarters of an inch ; breadth a quarter. 



This fpecies was firft noticed by Lister in Wales ; 

 and afterwards by Pennant as frequent in Angle fea, on 

 fandy foil near the coaft. It is certainly a local fpecies, 

 though very abundant in fome places near the fea, and 

 rarely, we behve, but in arenaceous foil, within the in- 

 fluence of faline air. On the coafl; of Caerma> thenjliire, 

 and on the hill above WIntfand bay in Cornwall, it is in 

 fuch vafl; profufion, that a perfon cannot ft^ep without 

 crufliing numbers. At the lafl place is a prevailing opi- 

 nion, that they contribute much to fatten fneep,* it is in- 

 deed impoflTible that thofe animals fliould browze on fuch 

 fhort grafs without devouring a prodigious quantity, 

 efpecially in the night, or after rain, when they afcend 

 the flunted blades.
