Glans domingensis (d’Orbigny, 1853) is a small clam that grows to about 6 mm (0.24 inch). The shell is squarish, with sharp, beaded radial ribs, and the shell margin is strongly notched, crenulated. The shell color is white with small, faint pink or orange spots. Do not confuse this species with the juveniles of its more common relative, the Broad-ribbed Carditid, Cardites floridanus. These latter are narrower, with the shell “beak” displaced to one of the sides. (In the figure, the inside of the valves may look "dirty," and viewers may think that curatorial staff at the National Shell Museum didn't care to clean the shell prior to photography. The dried “dirt,” however, are residues of the mollusk soft parts that may yield genetic information in the future, so it stays.)
