Monilea is a genus of sea snails in the family Trochidae, the top snails.
Description The solid shell has a depressed-conical shape. The outer surface is sharply, spirally striate and closely obliquely striate. The shell has a more or less developed callous ridge or funicle revolving on the inner side of the whorl within the umbilicus, and terminating at the columella, the edge of which is reflexed over it. The sinuous columella terminates in a point or denticle at its base. The outer lip is lirate within.George Washington Tryon, Structural and systematic conchology: an introduction to the study of the Mollusca, p.12; 1882H.
