Pachydermia laevis has a moderately large protoconch with regular overall interconnected reticulate sculpture, strongly marked in the proximal region and becoming finer and less distinct toward the aperture. The aperture is slightly curved with a thickened broad rim that tapers slightly toward the inner edge.

Pachydermia laevis is most likely to be confused with Unknown neomphalid W, as they are approximately the same size and both have reticulate sculpture. However, Unknown neomphalid W lacks the thickened aperture rim and its sculpture is coarser and less regular and is limited to the proximal half of the shell.
