the apex, and rise so much as to give the margin the 
appearance of having been rolled or gathered up, as one 
might gather lip the edge of a woollen cap while holding 
it in the hand : the shell appears to be tolerably thick. 
Hampton Common and Amberley Heath, near Minch - 
inhampton, Gloucestershire, afford this shell, in Bath 
shelly Oolite. I have to thank the Rev. Mr. Newton for 
my specimen, a token of some years standing ; it is cha- 
racteristic of the bed in which it occurs, where it is not 
very rare, and is generally in a very high state of pre- 
servation. 
PATELLA unguis. 
CAPULUS. Mont. 
TAB. CXXXI X.—Fig. 7. 
Spec. Char. Depressed, suborbicular, obscurely 
radiated ; vertex oblique recurved, extended 
beyond the base, acute. 
A rather flat shell, being about one -third of its width 
high ; the whole of the beak is solid ; the other parts 
gradually growing thinner to a sharp edge. The recent 
Patella ungarica of Linnaeus is so very similar to this 
fossil, that I doubt if a distinction can be found ; if there 
be any it lies in the radii, which are very obscure in this, 
a circumstance that may be attributed to wear; the 
beak is, perhaps, less oblique, but in this it is variable. 
My specimens came from the Holy wells Craig.
