Monilea callifera, common name shrewd trochid, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

The lusterless conoidal shell is narrowly umbilicate, more or less depressed, strong and solid.

The lirae are very closely and finely beaded by the oblique incremental striae which are prominent in the interliral spaces.

The columella is short, ending below in a denticle, concave above and reflected partly over the umbilicus, and over the termination of a strong spiral funicle, which almost fills the white umbilicus.

[3] This marine species occurs in the intertidal and subtidal zones along the shores of Australia (New South Wales, Northern Territory, Queensland, Western Australia), the Philippines, New Caledonia, Japan, India, Sri Lanka, the Andaman Islands.
