Triumphis distorta is a species of sea snail, a marine gastropod mollusk in the family Pseudolividae.

This is partly smooth, pretty strongly furrowed at its base, larger than all the others, and separated by a broad and deep suture, forming a kind of scaffold, which renders it very round above.

At their surface is seen, besides the longitudinal folds of which we have spoken, transverse striae which terminate in the body whorl.

The outer lip is striated internally, is thick above, and denticulated upon the remainder of its length.

The columella, sinuous in its middle, is covered by the left lip, which is pretty thick, and partially conceals at its base a grooved columellar callosity.
