I07 wliicli is also called after Bennett the naturalist (Afacropus Bcnnelti), does not leave the poucli of its mother permanently, until it is as large as a Rabbit. In the north of Australia, in the region of King George's Sound, there is a small Kangaroo which is not larger than a common Rabbit, and it is a very interesting example of how species may differ from the type of a genus. It has a slender and rather short tail, which is rather scaly, and has but a few hairs on it, but it is not very short. The ears are short and round, and the hind feet are short. The departure from the contiguration of the Great and Brush Kangaroo shape is therefore great. It ii called the Short-tailed Kangaroo. The hi-st four kinds mentioned are grouped together with others under a sub-genus, IlaliiuUurus (, a leap, and oipa, a tail).. THE BRUSH-TAILED ROCK KANGAROO. Almost as strange as the slender-tailed Kangaroo are those which are called the " brush-tailed," an<l which inhabit rocky situations {Macropm peniciUatus). Mr. Waterhouse thus notices them :— " Whilst the Kangaroos of the plain" have the fore part of the body slender and light, great .strength in the hinder parts, combined with a long leg and foot, adapting them to fleetness, the tail powerful, and assisting in the support of the long body, we perceive certain modifications in the form and structure of these parts in the Rock Kangaroos which adapt them to their particular habitats. The body, more compact in form, requires but little from the tail for its support, the leverage being less; and the feet are, though powerful, eompai'atively short, and remarkably rough beneath, being thickly covered over this part with hard tubercles, which no doubt prevent the foot from slipping. The nails of the two larger toes are shorter than usual, and, indeed, in some of the .species, scarcely project beyond th
