This is probably the shell to which Montagu al- 

 ludes, when, speaking of " Solen vespertinus,"' he 

 says, " not uncommon of a small size at King'*s 

 Bridge, Devonshire, and other parts of that coast."" 

 (Test. Brit. p. 54.) The Psammobia florida of La- 

 marck, with which Dr. Turton confounded this spe- 

 cies, is probably that form of Psammobia vespertina, 

 which is found on the Scotch coast at Loch Ryan by 

 Mr. Nicol, and which constitutes the " Psammobia 

 vespertina, var. 7?" of Phillippi.
