PER CURIAM:
The appellants brought this suit as a class action. Before the court reached a determination of appellants’ right to maintain this suit as a class action, the district judge ordered appellants to “amend their complaints so as to include ' as parties plaintiff all members of the alleged class who have retained counsel for the plaintiffs to represent them in these two cases.” Ten months later the district judge dismissed appellants’ suit with prejudice when appellants failed to comply with this order.
