GASTEROPODA. 17 



Mr. A. Bell gives this species from the Chillesford Bed of Easton Bavent Cliff, in ' Ann. 

 and Mag. Nat. Hist/ for Sept., 1870. 



Buccinum pseudo-Dalet, S. Wood. Supplement, Tab. V, fig. 4; Tab. VI, fig. 9. 



Locality. Cor. Crag, near Orford. 



Tab. V, fig. 4, represents a specimen lately obtained by Mr. A. Bell from the 

 Coralline Crag near Orford, which, though resembling B. Dalei, departs from that shell 

 sufficiently to entitle it, I think, to a distinct specific name, and I propose to call it 

 pseudo-Dulei. The exterior of the specimen is not quite perfect, but it appears to have 

 been covered with fine striae, smaller and finer than I have seen upon any specimens of 

 B. Dalei. The form of the aperture is also different, being more expanded at the base, 

 and the columella is more twisted. The apex of this specimen is obscured. There is 

 also a general angularity of aspect presented by the shell, in which it contrasts with 

 B. Dalei. 



Tab. VII, fig. 9, represents the fragment of a shell now in the British Museum 

 found in the Coralline Crag at Orford by Henry Woodward, Esq. ; it is marked as the 

 apex of B. Dalei, which I believe it is, or even more probably of the above pseudo-Dalei. 

 It seems from its depression and from the early expansion of the volutions to have belonged 

 to the present species, which in the perfect shell has unfortunately this part hidden. 

 Several fragments of B. Dalei in my cabinet from the Cor. Crag of Sutton have the first 

 two or three volutions filled with calcareous matter.

Tritonium — Fabr. Faun. Groenl., No. 397, 1780. 



Length, 2 inches. 



Locality. Red Crag, Sutton ? and Walton Naze. 



The figure of this species here given is from a recent shell in the British Museum, but 

 I have seen a perfect specimen that was, I believe, obtained by the late Mr. Edward Acton 

 from some of the nodule diggers in the parish of Sutton, undoubtedly belonging to this 

 species. This I should have preferred to figure, but I was not able to obtain it for that 

 purpose. There can be no doubt that it came from the Crag, and I have myself found 

 a fragment of what I believe belongs to this species at Walton-on-the-Naze.
