- Skeleton of Right incisor very large and chisel-like, Hind-Foot of Koala (Phas- molars with prominent transverse colarctus cinereus), showing ridges, as in Macropus, but without stout opposable hallux, folthe longitudinal connecting ridge.
FILANDER, the name by which the Aru Island wallaby (Macropus brunii) was first described.
- The Great Grey Kangaroo (Macropus giganteus).
In Macropus giganteus and its immediate allies, the premolars and sometimes the first molar are shed, so that in old examples only the two posterior molars and the incisors are found in place.
- Skull and teeth of Bennett's Wallaby (Macropus ruficollis bennettii): i l, i 2, i 3, first, second and third upper incisors; pm, second premolar (the first having been already shed); m l, m 2, m 3, m4, last premolar and three molars.
The typical genus Macropus, in which the muzzle is generally naked, the ears large, the fur on the nape of the neck usually directed backwards, the claw of the fourth hind-toe very large, and the tail stout and tapering, includes a large number of species.
Muelleri, although it is to some extent connected with Macropus by D.
The skull has a remarkably narrow and pointed muzzle and much inflated auditory bullae; while the two halves of the lower jaw are firmly welded together at their junction, thus effectually preventing the scissor-like action of the lower incisors distinctive of Macropus and its immediate allies.
