Papuan and Australian subregions. This family is a very distinct and sharply-defined one, its only ally being the Basijuridce, from which it diflxjrs in many important respects. Owing to the syndactyly of the hind feet of its members, it has been commonly considered as forming a connecting link between the Polyprotodonts and Diprotodouts ; but, judging from the wholly Polyprotodont character of the rest of their organization, even down to the structure of their carpal and tarsal bones, all of which show far greater resemblances to the Dasj/uridce than to the Pludanijeridce, it seems probable that this presumption is wrong, and that their syndactyly has arisen entirely independently of that of the Diprotodonts, a view under which we should look upon the * Said to be slightly prehensile in Peramoles hroadbcnti only, t The molars roundt^l and somii-rooted in Prraf/r//r ^ar/nf/s Please note that these images are extracted from scanned page images that may have been digitally e
