PLATE LXV. 



The Shells figured in the annexed plate are the true C. virgata of 

 Da Costa, but not the Helix Zonaria of Pennant, as that author has 

 erroneously considered them in his British Conchology. It appears 

 that the latter species came into the possession of Da Costa after the 

 work was published, for it stands corrected in some Mss. notes in his 

 collection, though it is not noticed in his publication. Gmelin in his 

 Systema Natura admits Da Costa's Shell as the Linnaean Zonaria ; 

 Pennant's Shell is not described by either author. 



It inhabits dry sandy soils and banks, and, as Da Costa observes, is 

 common only in some parts, as in the grass on Heddington-heath in 

 Oxfordshire, and in Hampshire in plenty. It is also found in Corn- 

 wall, and was met with by Petiver on Newmarket-heath in Cam- 

 bridgeshire.
