Shell Description
Shell subfusiform, with, somewhat of a quadrangular outline, thin and semitransparent, very glossy, horn-color, with a faint tinge of yellow, very slightly and remotely striate in the line of growth; periphery rounded, with a tendency to angularity; epidermis thin; whorls 4 ½ or 5, very convex and cylindrical, gradually increasing in size, the penultimate whorl as broad as the last, which occupies about two-fifths of the shell. Spire is shortish, but rather tapering, and blunt at the point. Suture is very deep.
Aperture is semioval, contracted or sinuous in the middle of the outer edge; teeth six or seven, viz. two on the pillar, two on the pillar lip (the inner one of which is always larger, and the outside one tubercular and placed in the angle where the outer lip joins), and two or three within the outer lip (the third, when it is present, placed near the pillar lip and being a mere tubercle:) outer lip rather thick and slightly reflected, strengthened by a strong rib both outside and inside, which is situate near the opening of the mouth and is yellowish-white; outer edge rather abruptly inflected; inner lip slightly thickened in full grown specimens; umbilicus small and narrow, contracted by a rather sharp and gibbous crest or ridge at the base of the shell.

Famous quotes containing the words shell and/or description:
“There are no small number of people in this world who, solitary by nature,
always try to go back into their shell like a hermit crab or a snail.”
—Anton Pavlovich Chekhov (1860–1904)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
