Alone among marsupials bandicoots have no clavicles.
Finally, there is the hypothesis that marsupials are the descendants of placentals, in which case, as was suggested by its discoverer, the placenta of the bandicoots would be a true vestigial structure.
It is urged that the imperfect placenta of the bandicoots instead of being vestigial, may be an instance of parallelism, and that in marsupials generally the allantois failed to form a placental connexion.
It burrows in the ground, but in other respects resembles bandicoots in habits.
Its general habits and food appear to resemble those of other bandicoots.
