PATELLA ancyloides. 



TAB. CCCCLXXXIV— /g. 2. 



Spec. Char. Convex^ 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. 



Very simple and regular in form, and perfectly smooth : 

 the apex is placed about halfway between the centre and 

 the anterior edge ; the ends are equally obtuse. 



Froai Ancliff with the last. 



One figure is enlarged.
