62 SUPPLEMENT TO THE CRAG MOLLUSCA. 
Mr. Bell (‘ Ann. and Mag. Nat. Hist.,’ May, 1871) gives this also from Walton, but 
I have not seen that specimen.

Locality. Coralline Crag, Sutton. 
An imperfect specimen of this species has recently been obtained by myself from 
Sutton. It has lost its obtuse apex and a part of the spire, but may, I think, be 
distinguished by its peculiar ornament. It is the only specimen I have seen.

Locality. Coralline Crag, Sutton. 
A single specimen was found by myself a few years since which I then considered as 
a new species, and had given to it the name of O. mitis. Upon showing the shell to 
Mr. Jeffreys he considered it as an identity with a British species which he had figured 
and described under the name of Odostomia minima (‘ Ann. and Mag. Nat Hist.,’ 1858, 
p. 9, Pl. XI, fig. 3); and my shell passed under that name in a report by him upon the 
dredgings of the Shetland seas (‘ Brit. Assoc.,? 1863). He has not, however, in ‘ Brit. 
Conch.’ identified Od. minima with any Crag shell, but speaks (vol. iv, p. 107) of Aclis 
Gulsone having been found by me in the Coralline Crag at Clacton (corrected to Sutton 
in vol. v, p. 210). I presume that the shell thus referred to is the single specimen of 
which I have been speaking, and I have accordingly adopted the specific name for it. ‘The 
figure above referred to is a copy from a figure of a recent shell, my specimen (which, I 
believe, is the only one that has been found) having been destroyed while in the hands of 
the engraver. ; ;
