|A shell of Pusula radians from Nicaragua on display at the Museo Civico di Storia Naturale di Milano|
J. B. Lamarck, 1810
The shell of an adult Pusula radians can be as long as 21 millimetres (0.83 in), with a diameter of about 15 millimetres (0.59 in). The shell is ovate and pinkish. It has small pale brown spots and wart-like tubercles on the dorsum, and strong transverse ribs on the base. As is the case is all the members of this family, the aperture runs the length of the shell and has teeth along the margins.
