Mr. Gould exhibited and pointed out the characters of two new 
species of Kangaroo. The first of these belongs to the section to 
which Mr. Gray gave the name Petrogale, as was described under 
the name <

This species of Petrogale is remarkable for its small size, the gene- 
ral pale colouring and the bright rusty tint of the upper parts of the 
body ; these parts are freely pencilled with whitish and with brown ; 
the sides of the neck and body are of a delicate yellowish hue, or 
might be described as very pale rust, and this is the prevailing hue 
of the head, which is nearly of a uniform tint; but is white, or 
nearly so, on the sides of the muzzle at the tip, and there is a trace 
of the usual white mark on the cheeks; above the eye is a spot of a 
pale rust-colour, and an indistinct brownish mark running towards 
the nostrils from the front of the eye; the ears are clothed within 
with white hair; externally they are of the same palish rusty yellow- 
ish hue as the upper surface of the head ; the chin, throat and whole 
under parts are white, with a faint yellowish rusty tint ; the outer side 
of the hinder legs is of a brighter tint than the sides of the body, but 
less red than the back; the feet are of a very pale brownish colour, 
freely pencilled with dirty white; a small space at the. base of 
the tail is covered with fur of the same texture and colour as that 
of the body; beyond this the hairs of the tail are harsh, at first 
about half an inch or rather more in length, but becoming gradually 
longer towards the apex, where they are more than an inch long; 
these hairs are of a yellowish white colour, but the apical third of 
each hair is black. This species was brought to England by Lieut: 
Emery, of H.M.S. Beagle, and is now in the British Museum. 
The second species belongs to the section or genus Halmaturus, 
and received from Mr. Gould the specific name Binoé, in honour of 
No, CXII.—Procrepines or THE Zoot. Soc,
