nina, p. 334. t. 4 f. 15. Buc. pupa, id. t. 4. f. 14). 

 This unique specimen was recently found in the red crag of Wal-

 cabinet. 



1. Buccinum Dalei, Sow. (Min. Con. t. 486. f. 1, 2). 



Ramsholt. | Walton Naze. | | 



The difference between this and Buc. ovum, Turt. Zool. Journ. 

 xi. p. 366. t. 13. f. 9, is in the striae with which the former is more 

 or less ornamented, and it has rather a deeper suture.

(var. /3.), Min. Con. t. 486).

 from the crag.
