chambers are lined with Carbonate of Lime: it is from 
Cropredy. Fig. 2. is half a nodule of indurated Marle, 
containing a similar shell, from Whitby. Figs. 3 and 4. 
are two views of a small specimen given me by EH. 
Strangeways, Esq. from the neighbourhood of Imin- 
ster: the same Gentleman has likewise given me a spe- 
cimen from Whitby. The large specimen, fig. 5. is 
remarkable for the gibbosity of its whorles ; but in other 
respects it does not differ from the small one, fig. 4, in the 
centre of it. It is from the same place, by favour of my 
valued friend, the late Cunnington, Esq. It is in 
indurated Marle, with some few grains of Hydrate of 
Tron, indicating an approach to the inferior Oolite.
