Shell is small and discoidal, similar to Umbonium elegans but the surface is sculptured with fine concentric grooves. The umbilicus is smaller and less inflated and the color may vary but is mainly dark greenish-grey with yellow streaks and pink sutures. The umbilicus is dark brown to black and the aperture is nacreous green.
Found in open coasts. Occurs at the low tide mark (Ref. 349).
