Eulithidium Pilsbry 1898

Eulithidium is a genus of small colorful sea snails, marine gastropod mollusks in the family Phasianellidae, the pheasant shells.^[1]

Several species in this genus were originally placed in the genus Eucosmia. However, the name Eucosmia was pre-occupied in zoology for a group of moths established by Stephens in 1829. The molluscan Eucosmia was therefore called Eulithidium to distinguish it from the group of Lepidoptera.^[2]
