The experience of Mr. Albany Hancock is opposed to the 

 observation of Mr. Spence Bate, that this mollusk does not bore 

 through the epidermis of the mussel. The former of these 

 excellent observers remarks that it is indifferent what epidermis 

 or shell be opposed to its progress : and has obligingly sent us 

 specimens which indubitably prove his case ; an important point, 

 since this is one of the strong facts against the notion of a solvent 

 being the agent used in boring.

Add to the synonym Buccinum tuberculatum a reference to 

 Fleming, Brit. Anim. p. 341. — Brit. Marine Conch, p. 219 ; both 

 which descriptions are copied from Turton's Conchological Dic- 

 tionary. 



Vol. iii. p. 408. Buccinum Dalei. 



Through the kindness of Mr. Howse, who obtained the speci- 

 men, and Mr. Alder, who examined it, we are enabled to give some 

 notice of the soft parts of this most rare and interesting mollusk. 

 " Its tongue differs," writes Mr. Alder, " from that of Buccinum 

 undatum, as well as from those of the allied species of the genus 

 Fusu&, and makes a slight approach to that of Mangelia. It has a 

 single plain and slightly-curved tooth on each side, and a very thin 

 non-denticulated plate in the centre. The Fusus it comes nearest 

 to is F. Turtoni, whose tongue I have also examined." In the 

 sketch sent of the latter the curved lateral teeth are broader at 

 the bases than the former, shorter, and have two small lobes or 

 denticular processes at junction of the broad part with the hook 

 at the inner side of the centre plate, which, as in the former, 

 has no denticles. 



" Mr. Howse got two or three specimens of Buccinum Dalei from
