PATELLA ancyloides. 
TAB. CCCCLXXXIY— Jig. 2. 
Spec. Char. Con vex, smooth ; apex spiral; base 
oval. 
A small shell, without any strongly marked character 
except the decidedly spiral apex, which being turned to 
one side makes it resemble the Ancylus fluviatilis; but 
it is more depressed, and from the shells that accompany 
it, we would judge it to be marine ; the apex is very 
much inclined towards the anterior edge. 
Found with the following and many other minute or- 
ganic remains at AnclifF, by the Rev. G. Cookson. 
The larger figure is magnified. 
PATELLA nanus. 
TAB. CCCCLXXXIV.— /g.3. 
Spec. Char. Obliquely smooth ; base oval; apex 
obtuse. 
V ery simple and regular in form, and perfectly smooth : 
the apex is placed about half way between the centre and 
the anterior edge ; the ends are equally obtuse. 
From Ancliff with the last. 
One figure is enlarged.
