Comments on HES’s Report ["Report of a committee … (on) nomenclature of zoology", Rep. BAAS 12 (1842): 105–21]. Suggests limit be put to changing names that are only partially erroneous to prevent those who detect the error from coining new names and attaching their own. HES’s rule for "authority for a species" is difficult, though on the whole best. Suggests stating it boldly to prevent appropriation of species names by "tacker[s] of two old names together".
