A hermaphroditic sea urchin, Strongylocentrotus purpuratus, with three ovotestes and two testes is described. Neither cleaving eggs nor embryos were found in corpore. Fertilization inter se gave normal larvae. The specimen was collected from Palos Verdes, Calif., a region which has yielded an unusually large number of hermaphroditic S. purpuratus.
