Monilea smithi

Monilea smithi is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

The 6 to 7 whorls are encircled by numerous unequal, grained, partly pearly riblets.

The convex base is sculptured with smoother riblets, their interstices cancellated.

The columella is deeply sinuous, callous, terminating in an acute denticle.

The outer lip is sulcate within, subcinereus or ashen-reddish, with scattered obscure spots on the upper whorls.
