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. 
Buccrnum psEupo-Dauet, S. Wood. Supplement, Tab. V, fig. 4; Tab. VI, fig. 9. 
Locality. Cor. Crag, near Orford. 
Tab. V, fig. 4, represents a specimen lately obtamed by Mr. A. Bell from the 
Coralline Crag near Orford, which, though resembling B. Da/e?, 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 striee, 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, Hsq.; 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. Dale: in my cabinet from the Cor. Crag of Sutton have the first 
two or three volutions filled with calcareous matter.

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.
