AURICULA buceinea. 
TAR. CCCCLXV.— j%. 2. 
Spec. Char. Subovate, inflated, smooth ; spire 
short, acute ; base notched ; three sharp 
plaits upon the columella ; left lip callous; 
right lip with a thick border. 
Syn. Yoluta buceinea, Brocchi , 319. t . 4 .f. 9. 
D istiNguisheo from A. turgida, M: C. 163, and other 
similar shells by the regularity of its form, smooth sur- 
face, short spire, and plain outer lip. The upper plait 
in the aperture is partly concealed by the callus upon the 
left lip, and the lower is the spiral edge of the columella; 
the length and breadth are in the proportion of 3 to 2, 
nearly. 
Collected in the Crag, at Ramsholt, by the Rev. 
G. R. Leathes, 
The shells upon this plate with their analagous species, 
agree so exactly with Lamarck’s Auricula ringens, that 
they must be included in the same Genus ; bi^t the notch 
at the base of the aperture perfectly distinguishes them 
from that under which Lamarck has placed them. 
Brocchi has referred his Yoluta buceinea, with two other 
very different shells to Marginella, but without sufficient 
reason. They have strong claims to he united under the 
Genus Nassa, and are somewhat related to Columbella; 
whether it will be necessary upon a revision of the fossils 
in this work, to create a new Generic division for their 
reception, is at present a question. They are in all 
probability marine reliquia.
