This interesting species of Bulla, which has lately been found 

 in Devonshire, and considered as a new discovery, was first in- 

 troduced to the notice of English Conchologists by the Rev. Mr. 

 Cordiner. He discovered them some years ago on the shores of 

 BamfF, one of the Scottish islands, and sent them, with several 

 others, disposed in a grotto work, as a present to the late Du- 

 chess of Portland. Since that time they have been found at Ly- 

 mington, in Dorsetshire, by Mr. Keate ; and lastly, during the
