Pseudovertagus aluco, common name aluco vertagus or Cuming's cerith, is a species of sea snail, a marine gastropod mollusk in the family Cerithiidae, the ceriths.

[1][2] This species is present in the Indo-Pacific from the Eastern Africa to Philippines, and in Australia (Northern Territory, Queensland and Western Australia), the Samoan Islands and New Caledonia.

[3][4] Pseudovertagus aluco can be found on sand-bars at the high tide level, on tidalflats, on clean sand and coralrubble.

[3] This species possess high-spired shells with a small aperture and a few spiral rows of tubercles.

These sea snails usually extend their proboscis and foot deep into the sediments, rather than burrowing below the surface.
