SCAPHITES. 
Gen. Cuar. <A concamerated shell, commencing 
with a depressed volution, the last turn of 
which, after being enlarged and elongated, is 
diminished and reflected imwards. 
SCAPHITES equalis. 
TAB. XVIUIL—Figures 1, 2, and 3. 
Seec. Cuan. Invyolute, umbilicated, inner whorles 
concealed, surface with projecting distant radii 
extending all round the whorle; outer part 
rounded with about two projecting striae be- 
tween and equal to each of the radii; outer 
whorle ventricose, the radii upon it much en- 
larged, and abruptly terminated before they 
reach the edge.

"Tus is an even shell, a little more than an inch long. On 
account of the imperfection of the specimen, I am not sure 
that the mouth is incurved. 
I received this specimen some years ago, by favour of the 
indefatigable and highly intelligent Dr. W. E. Leach, 
from Yeovil. I place it under Mr. Parkinson’s new genus 
Scaphites, not with the strictest propriety, but in the present 
infant state of our knowledge, it may be convenient, as it 
agrees so nearly with the next. Figure 1, is a side view. 
Figure 2, shews the front with the volution central and a 
flinty grain or two of sand. Figure 3, is a section through 
one of the concamerations, exposing part of the undulations, 
not always to be seen in such marly stone casts. The coat 
or remaining part of the shell has a little of the pearly lustre. 
It is from the green sand formation.
