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 aliquanth brevi, molli, 

 splendide fulvo ; guld, corpore infra, artubusque albidis, hie 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. I'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 Ma- 

 cropus Bennett it. 



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. 



Halmaturus agilis, Hal.fulvus, supra nigra adspersus, infrd.
