Bulla utriculus ? Brocchi. Addendum Plate, fig. 26. 



Bulla utriculus, A. Bell. English Crags, p. 19, Proc. Geol. Ass., 1872. 



Locality. Cor. Crag, Gedgrave. 



The specimen in the above figure was sent to me by Mr. Robert Bell, with the name 

 B. utriculus, Broc, attached, being that under which it was inserted by Mr. A. Bell in his 

 paper on the 'English Crags,' p. 19. Upon examination I find this specimen to be quite 

 free from striae of any kind, while utriculus is punctato-striated. It does not corre- 

 spond with Brocchi's figure of either species. 



It resembles, in its freedom from strias, both Brocchi's and Homes' figures of 

 miliaria ; but the figures of these two authors do not accord with each other in respect to 

 the general form of the shell. Under this uncertainty, although I am inclined to refer 

 the Crag shell to miliaria rather than to utriculus, I think it likely to give rise to less 

 confusion if I figure it under the name in which it first appeared in Mr. Bell's list of the 

 ' English Crags.' 



The shell is umbilicated at both ends, and particularly so at the base.

In order to confirm the statements and fragmentary figures already put forward in 

 this Supplement, page 22, and Tab. V, fig. 20, I have had represented a very perfect 

 specimen obtained by Mr. Canham from the Cor. Crag, near Orford, which measures one 

 inch and three quarters in length. The shell is beautifully smooth and glossy, even to 

 its posterior termination, without a vestige of striae, which, had they ever existed, could 

 not fail to appear on so beautifully preserved a specimen. The terminal slit is very 

 narrow, and nearly one fourth the length of the entire shell.

A single specimen, as above referred, was found by Mr. Canham, and it is the only 

 one I have seen from the Crag ; it was accompanied with specimens of Helix hispida,
