Note. — Since the publication of plate VI. I have found in the MSS. of my friend Dr Leach some observations on 
Figs. 8, 9, 10 of that plate ; wherein he says, that he has found out that they are not the Balanus Scoticus cf 
Wood, but a new shell which he had named Balanus candidus ; and had " placed it in the exotic collection 
of the British Museum," as he doubted the authority of the person who found it. I have just seen some beau- 
tiful and perfect specimens of this rare shell, found in the Firth of Forth by my friend James Gerard, Esq., 
Pitt Street, Edinburgh, and in his cabinet. This, taken in connection with the authority of my friend Mr W. 
C. Trevelyan, must establish it as a British species. The synonyms of those shells must stand thus :
