Genus CINULIA, Gray. 
The genus Cinulia of Gray, was founded upon Auricula globulosa, of 
Deshayes, a subglobose shell, with a comparatively very large body-whorl, 
a short, abruptly attenuate spire, and a single obscure oblique fold on the 
thickened columella. Its outer lip is thickened and reflected without, and 
smooth within; its aperture is narrow, and its surface marked with 
revolving striz. D’Orbigny, in subsequently proposing to found a genus 
for this and similar shells, under the name Avellan bes first in that 
conneetion, the same species (Auricula globulosa), so that his genus be- 
comes exactly synonymous with Cinulia of Gray. d’Orbigny, how- 
Subgenus Avetuana, d’Orbigny. 
Shell globose ; body-whorl large; spire much depressed ; aperture 
narrow, arcuate, sometimes a little sinuous below; outer lip srongit 
thickened without, crenate within; columella thickened, and provi led 
with two or three prominent transverse folds; surface with revolving ust 
ally punctate striz. ;
