This species commences the second section of the genus, 
in which the upper part of the whorls, instead of being 
coronated, is produced into an undivided ledge, and the 
shell is more covered by the mantle. In C. proboscidale 
the left side of the mantle covers the shell entirely, secre- 
ting a vitrified glazing over the surface, which is generally 
roughened in parts with pimples arising from the inter- 
vention of particles of sand or some such substance. The 
upper ledge of the whorls is so produced in this species 
as to form a broad hollow channel around the spire, en- 
tirely concealing the apex from view by its callous deposit 
of enamel. Both ends of the shell are attenuately con- 
tracted, the contraction increasing with age. It has no 
coloured bands or marking.
