Description

The height of the shell attains 8 mm, its diameter 8 mm. The very thinshell is very elegantly sculptured. It is livid, spotted with pale rufous-brown. The protoconch consists of 2 whorls, very tumid and smooth. The apex is mammillated. The teleoconch consists of 4 whorls. These are tabulated, with their sutures nearly rectangular. Upon the

spire A spire is a tall, slender, pointed structure on top of a roof of a building or tower, especially at the summit of church steeples. A spire may have a square, circular, or polygonal plan, with a roughly conical or pyramidal shape. Spires are ...

there are two or three carinae, and intercalated carinulae. The entire surface is most elegantly and densely radiately costate. The costae are very acute, subgranulose upon the carinae. The interstices on the first whorl are fenestrated, posteriorly decussated. The base of the shell is deeply rounded. The shell is sculptured with about 5 lirulae, anteriorly granulose. The umbilicus is large, closely ornamented with about 3 spiral distant lines, and radiating costulations continued from the base. The umbilicus is bounded by a granular keel, but has three other distant spiral lines crossing the lirulae. The rounded

aperture In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An opt ...

is indentated by the carinae, scarcely in contact parietally, iridescent inside and nacreous. The operculum is very thin, multispiral, with about 10 elegantly rugulose whorls. The aperture is sculptured with delicate waved radiating lines.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia
