AURICULA pyramidalis. 
TAB. CCCLXXIX. 
Spec. Char. Ovate, pointed, smooth ; spire 
pyramidal ; volutions rounded above, the 
last subcylindrical short; aperture half the 
length of the shell, with a sharp outer lip, 
and two plaits upon the columella. 
A thick rather clumsy formed shell, with a prominent 
base and small umbilicus ; the plaits upon the columella 
do not project much, they are near together, the inner 
lip is rather thickened, the outer one not at all. 
As the Genus Auricula is supposed to contain only 
land shells, it may be questioned whether the subject of 
this plate be properly arranged among them ; but it 
agrees well with Lamarck’s second division, formerly 
called by him Conovulus; and it is not unlikely that a 
formation of so late a date as the Crag appears to be, 
should contain land shells, since it is found to hold 
several marine species precisely like those of the present 
day, although land shells have not been hitherto suspec- 
ted in it. The Auricula incrassata, and A. turgida, tab. 
163. found in the Green Sand, ought in all probability, 
to be removed to another, perhaps a new, Genus. We 
first received this species from Mrs. Cobbold of Ipswich, 
so long ago as in 1812. (see fig. 2.) but could not be
