Roseaplagis artizona

The sculpture consists of fine spiral lirae, about 15 on the penultimate whorl.

It has a light yellow colour with radiate oblique broad streaks of dark brown.

The epidermis is very thin, the pearly inner layer shining partly through it.

The protoconch is small, acute, and consists of two convex, light-brown, and finely spirally striate whorls.

The outer and basal lip are sharp, angled where they meet, margined with a white bead.
