Hab. Port Essington, North coast of Australia. 
Mr. Gould observed that the Petrogale robusta should also be re- 
ferred to this section. 
Of the second species Mr. Gould regretted he was not able to lay 
before the meeting a perfect specimen ; the skin, however, which he 
exhibited, though imperfect, in his opinion exhibited characters not 
found in any species hitherto described: they are, 
OspHRANTER(?) IsABELLINUS. Osphr. vellere aliquantd brevi, molli, 
splendide fulvo ; guld, corpore infra, artubusque albidis, hic atque 
illic flavescente leviter tinctis. 
Longitudo corporis circiter 36 unc. 
The general colour of the skin is bright fulvous or sandy red; 
the fur is rather short and soft to the touch; the hairs are uniform 
in tint to the base: the throat and under parts of the body are 
white, faintly tinted with yellowish in parts. The fur on the belly 
is long and very soft: the white or whitish colouring of the under 
parts, and the uniform fulvous colouring of the upper parts and 
sides of the body, do not blend gradually. ‘he colour of the tail is 
nearly the same as that of the body, but is rather paler, and is nearly 
uniform. The fore-feet and toes above are covered with brown hairs, 
but on the sides of the toes the hairs are yellowish. ‘The size of the 
animal is probably about equal to that of the Macropus Bennettii. 
This skin was procured at Barrow Island, on the north-west coast 
of Australia, by Capt. Stokes, of H.M.S. ‘ Beagle,’ and transmitted 
by him to Mr. Gould, that its characters might be published. 
The third species is thus named and characterized.
