220 Mr. Ogilby's Descriptions of two new Kangaroos. 



and form in this respect a striking contrast to the sombre hue of 

 the toes ; the under surface of the tarsus is naked and callous ; the 

 belly and under parts of the body are very light hoary grey, the fur 

 here being equally long and dense as above, and of the same deep slaty 

 brown colour at base, but with a long and conspicuous hoary point ; 

 the tail of middling size, attenuated, dirty yellowish grey, with a 

 small, brown, obscurely tufted tip, and very nearly naked beneath, 

 the hair being worn short and bristly on the terminal half ; the ears 

 pretty large, rounded, with dirty white hair about the edges, within, 

 densely covered with long soft hair without, grizzled at the base, but 

 dark brown with a shade of russet on the terminal two thirds. The 

 two front incisors larger than the lateral, separate at the base, con- 

 verging at the point ; the external lateral incisor twice the size of 

 the middle one, and divided in the proportion of about 2 : 3 by a 

 vertical duplicature on the outer face, giving the tooth at first sight 

 the appearance of being double. The claw of the great hind toe is 

 short, round, and blunt, as in M. penicillatus ; and M. fruticus is the 

 only kangaroo besides that species in which I have noticed this cha- 

 racter. Length, 2 ft. 9 in. ; tail, 1 ft. 10 in. ; head, 54 in. ; ear, 3 in. ; 

 tarsus to the origin of the great claw, 7f in. 



Macropus (Halmaturus) rufiventer, the Wallabee of Van Diemen's 

 Land. — This is a very different species from the Wallabee of New 

 South Wales, (M. Ualubatus,) being smaller, and of a more reddish 

 brown colour. It is considerably smaller than the last species (M. fru- 

 ticus), but has similar incisors, except that the middle pair are not 

 proportionally longer or larger than the lateral, and the duplicature 

 of the external so small as to be apparent only on the posterior face, 

 dividing the tooth in the proportion of about 1:3; this tooth is 

 itself of smaller dimensions comparatively speaking than its ana- 

 logue in M. fruticus. The general colour of M. rufiventer is greyish 

 brown above, considerably darker than the wild rabbit, and deeply 

 shaded on the back and croup with pure black hairs, which, in cer- 

 tain lights, give these parts a perfectly black shade ; the paws and 

 outer face of the fore legs are of the same colour ; the tarsus and 

 hind legs brown ; the chin, throat, belly, and abdomen, sandy red, 

 more or less intense in different specimens ; ears yellowish red 

 within, black or very dark brown on the outside ; tail short, rather 

 darker than the body above, dirty yellowish on the sides, naked and 

 granulated for two thirds of its length on the under surface ; claws 

 long and pointed ; nose naked ; length of the body, 2 ft. ; tail, 

 1 ft. 2 in. ; head to root of ear, 4-^ in. : ear, 1-t- in. ; tarsus to great 

 claw, 5i in. First described before the Zoological Society, February
