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- 

 ton-on-the-Naze by Mr. Charlesworth, and liberally deposited in my 

 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 strise with which the former is more 

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

(var. fi.), Min. Con. t. 486).
