Description
The shell is glossy and lemon-shaped, with 20-30 transverse ridges. The upper part of the shell is a uniform very pale brown in color; there are no pigment spots present on the shell, but sometimes there are dots on the mantle of the animal.
The shell length is up to a maximum of about 10 mm and a width of about 8 mm.
The mantle is covered with many papillae. It has a light colour in deeper waters, but becomes darker between tide marks. The foot is light yellow or light orange. The admedian teeth of the radula have denticles. The penis is flat and broad.
The larvae have a light stomach and intestine. In the veliger stage they have a four-lobed velum (a structure used for swimming and particulate food collection) with very long lobes.

Famous quotes containing the word description:
“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)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
