If the defendant is a corporation, it is sufficient to state the corporate name of the defendant in an indictment, or to state any name or designation by which it has been or is known or by which it may be identified, without an averment that it is a corporation or that it was incorporated according to law.
If the defendant is a partnership or other association of persons not incorporated, it is sufficient to state any proper name of the partnership or association, or to state any name or designation by which it is known, or to state the names of all the persons in the partnership or association, or to state the name of one or more persons in the partnership or association referring to the other or others as "another" or "others." It is not necessary to state the legal form of the partnership or association.
