Description
The length of the shell attains 6 mm, its diameter 3.75 mm.
(Original description) The small shell has a columbelliform shape. It is white, spirally banded with bright yellow, centrally on the upper
whorls, and twice, at the periphery and towards the base, of the
body whorl. The shell contains 6 whorls, in our specimens imperfect as regards the
protoconch. The three remaining whorls are angular below the impressed sutures, everywhere closely and obliquely ribbed, crossed by spiral incrassate lines, beautifully gemmate with small globular shining nodules at the points of junction, so that the whole surface is cancellate, the interstices being deep and smooth. The outer
lip
The lips are the visible body part at the mouth of many animals, including humans. Lips are soft, movable, and serve as the opening for food intake and in the articulation of sound and speech. Human lips are a tactile sensory organ, and can be ...
is thickened, crenulate without, eight or nine denticled within. The sinus is rather narrow, but deep and conspicuous. The columellar margin is slightly plicate, fairly straight. The
siphonal canal is short.
