It is true that the description and illustration of E. Jurcata were given by Ehrenberg (1873o, p. 308; 18736, p. 288-289, PI. 6 (III), fig. 6, respectively) later than those of E. muelleri by Haeckel (1862, p. 508-510, PI. 30, figs. 5-10). Because only the spe- cies name was mentioned, however, and because the two asterisks were included, Ehrenberg's action is here presumed to constitute an indica- tion as specified in Article 16 (a) (v) of the Inter- national Code of Zoological Nomenclature (Stoll and others, 1961). Therefore E. jurcata is consid- ered to be a valid name and consequently has priority over E. muelleri.
