APPENDIX. 309 
One specimen only of this species, obtained by myself, is all that I have seen. It appears to be full 
grown, though its sharp and reflexed outer lip is destroyed, but in all its other characters it perfectly 
resembles the recent shell.

Two or three specimens only of what most probably belonged to this species are all that I haye seen. 
They were obtained at Copford by Mr. John Brown, who has obligingly permitted me to have them 
described ; they are unfortunately not in a very good state of preservation. The best specimen appears to 
correspond with the recent shell; but not being full grown, it has only five volutions instead of six, and is 
evidently an immature individual, consequently wants the reflexed lip, the character of maturity. It differs 
from rufescens, which is more depressed ; and from /ispida in having a smaller umbilicus ; and our fossil is 
more globose than either. The identification is not, however, perfectly satisfactory, and it would be desirable 
to see a few more and better specimens.
