Turris ruthveniana Melvill, 1923 Lophiotoma ruthveniana is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.

Original description: The thick shell has a fusiform shape.

The colour of the shell is bright chestnut brown, with squarrose, fairly regular, white tessellations on the spiral carinae.

These revolving keels appertain throughout — one, in particular, central, and subdivided by a shallow sulcus.

The lesser tornate keels increase numerically in each of the lower whorls, till, on the body whorl, they total five or six, all beautifully variegated with white and chestnut alternately, as mentioned above.
