the latter. Dorcopsis is confined to New Guinea, and contains three species, viz. D. muelleri, D. luctuosa, and D. macleani. D. muelleri has a striking resemblance to Macropus brunii, with which it has been confounded. Though intermediate between Macropus and Dendrolagus, these Kangaroos are not arboreal.
The genus Dendrolagus is remarkable for its un-kangaroo-like habit of living in trees. In accordance with this change of habit is a relative shortening of the hind-limbs, a feature which begins to be observable in Dorcopsis. "The general build," writes Mr. Thomas, "is of the ordinary mammalian proportions, not macropodiform at all." The muffle is not naked for the greater part, though the shortness of the hairs gives that effect. As in Dorcopsis, but not as in Macropus, the bulla tympani is not swollen. There are altogether five species, the fifth, D. bennetti, having been lately described from specimens living in the Zoological Society's Gardens.
