Note. — Having sent a few valves of our supposed Leda 

 bellula, A. Ad., to Mr. E. A. Smith, I.S.O., of the British Museum, 

 he most obligingly compared them with the type, and wrote

 They are more inequilateral — that is, the posteri/)r half is rather 

 longer in proportion to the anterior, the transverse sculpture is 

 finer, and the posterior escutcheon decidedly broader.^''
