Original Description (from Conrad, 1833, p. 344-345):
"Shell suborbicular, compressed, with regular concentric striae, and covered with a very thin pale brown deciduous epidermis; anterior and posterior sides each with an obscure fold; beaks central, not elevated; hinge edentulous; anterior muscular impression not greatly elongated. Length, one inch.
This shell resembles the fossil L. anodonta, of Say, but is very distinct. It was found near Pensacola by Dr. Hutchins, who sent it to Dr. S. G. Morton."
