Buccinastrum paytense, common name the Payta buccinum, is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, the Nassa mud snails or dog whelks.

Its ground color is whitish, marked with longitudinal reddish lines.

The epidermis which covers it, is pretty thick, and of a beautiful chestnut color.

The whitish aperture is ovate, slightly narrowed towards the upper part, and widened at the base, which is rather deeply emarginated.

The columella shows a white callosity, adhering to the body of the shell, and partially formed by the left lip.
