Petrogale brachyotis, Gould in Proc. of Zool. Soc., for Oct. 1840. 
Tuis new species of Rock-Wallaby was presented to me by Captain George Grey, the present Governor of South 
Australia, who procured it on the north-west coast while traversing that previously unexplored region. Only two spe- 
cimens were collected: these fortunately proved to be a male and a female, and apparently adult. It differs from 
most of the other species with which I am acquainted in the shortness and scantiness of its hair, which may, perhaps, 
be attributed to the great heat of the latitudes it inhabits, and the peculiar localities to which the animal resorts, viz. 
hard craggy surfaces exposed to the burning sun. The following account, which has been kindly furnished me by 
His Excellency, is all that is known respecting it :— 
“ I procured this species near Hanover Bay, December the 29th, 1837. It is excessively wild and shy in its habits; fre- 
quenting in the day-time the highest and most inaccessible rocks, and only comes down to the valleys to feed early in the 
morning and late in the evening. When disturbed in the day-time it bounds among the roughest and most precipitous rocks, 
apparently with the greatest facility, and is so watchful and wary that it is by no means easy to get a shot at it. How it can 
support the excessive heat of the sand rocks amongst which it always lies is to me truly astonishing, the temperature there 
during the hottest part of the day being frequently 136°. I have never seen this animal on the low land or the plains, and I 
consequently believe it to be entirely an inhabitant of the mountains.”’
