For numerous other emendations of nomenclature, corrections of 
synonymy, etc., the paper itself must be consulted. Several of the pro- 
posed alterations of the generic or specific denominations in common use, 
cannot be approved, as they are based upon misconceptions of the law of 
priority, or, in some instances, quite arbitrary.
