INDRI  , a Malagasy word believed to mean " there it goes," but now accepted as the designation of the largest of the existing Malagasy (and indeed of all) lemurs . Belonging to the

family Lemuridae (see PRIMATES) it typifies the subfamily Indrisinae, which includes the avahi and the sifakas (q.v.) .
