Vaceuchelus profundior, common name the deepwater top shell, is a species of sea snail, a marine gastropod mollusc in the family Chilodontaidae.

Its colour is whitish to yellowish, with irregularly scattered dark brown spots on the keels.

The body whorl has eight keels, the two at the periphery the strongest, the last, which is nodulous, encloses the umbilical area.

The keels and interstices are crossed by numerous fine axial riblets, about 25 to 30 on a half turn of the body whorl.

The columella is smooth — not toothed — reflexed, so as to hide the small umbilicus from a front view.
