Clathrodrillia solida, common name the solid drillia, is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

[1][2] The color of the shell is deep chocolate-brown.

Its longitudinal ribs are separated by wider interspaces, crossed by revolving raised lines, forming granules.

It is smooth and slightly concave above the periphery, with a raised line next the suture.

[3] This marine species occurs in the Caribbean Sea, the Gulf of Mexico and in the West Indies.
