The registrars of voters in each municipality in which an enrollment session is to be held shall give notice of such session, and of the purpose, day, hours and place thereof, by publication in a newspaper published in or having a circulation in such municipality, not more than fifteen nor less than five days before such session. Nothing in this section shall require that such publication be in the form of a legal advertisement. In each municipality divided into voting districts, any session for enrollment in such municipality may, if the registrars of voters so decide, be held in each such district by assistant registrars of voters appointed under section 9-192, provided the registrars of voters in the notice shall specify the place in each such district in which such session is to be held. When such a session is so held in each such district by such assistant registrars of voters, within forty-eight hours after the close of each of such sessions, each of such assistant registrars of voters shall deliver to the registrar of whom he is the appointee a true and attested list or lists, as made by such assistant registrars of voters at such session, showing all enrollments and corrections, if any, by them made, together with a list of all applications rejected under the provisions of sections 9-60 and 9-63.
