BuLua urricutus? Brocchi. Addendum Plate, fig. 26. 
Bunia urricutus, 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 striz of any kind, while wfrécwdus is punctato-striated. It does not corre- 
spond with Brocchi’s figure of either species. 
It resembles, in its freedom from strie, both Brocchi’s and Hdérnes’ figures of 
miliaris ; 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 mlaris rather than to wtriculus, 1 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, 1 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 striee, 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,
