EUOMPHALUS angulosus. 
TAB. LH — Fig. 3. 
Spec. Char. Above sub imbricated, with three 
spiral projections,, beneath striated, with live 
obscurely plaited spiral projections. Aperture 
obscurely octangular. 
The upper surface is nearly as in the last. On the under 
side the transverse plaits are partly obsolete in four lon- 
gitudinal ranges, between the five ridges, forming three 
sharpish angles to the upper, and five to the lower half of 
the aperture. Diameter less than an inch. The ridges do 
not always interrupt the inner contour of the aperture. 
The specimen from which this drawing is taken, is in 
the valuable collection of the great friend to this branch of 
Natural History, Thomas Meade, Esq. It is altogether a 
little disturbed, as if it had been in a soft state when it 
became petrified, and is thus irregularly round. 
These three species all partake of an appearance as if 
from a similar Limestone stratum. I have seen one from 
Benthall edge that looked as if it were from the same, but 
not well enough preserved to enable me to determine to 
which species it belongs ; Mr. Parkinson’s PI. 6, f . 7 and 8, 
is nearly in the same predicament : is it not my Fig. 2, from 
the appearance of the under side ?
