The purple lilliput is a small but relatively thick-shelled species, rarely larger than 40 mm in length. There is sexual dimorphism in shell shape with the male shell roughly elliptical and the female shell more round due to an expansion of the posterio-ventral margin to accommodate the marsupium. The periostracum is dark brown or black. The nacre is typically purple. (Parmalee and Bogan 1998)
