HORN EXPEDITION—MAMMALIA. 
15 
Of five specimens secured at Paisley BlufiT, in the McDonnell Ranges, four 
were females, and each had a single, fairly-developed young one in the pouch. The 
teats are four in number. All the specimens seen were of the typical colouration. 
In each of six skulls secured at Alice Springs (two “ aged,” two “ adult,” and 
two immature) there is only one premolar present on each side of each jaw. In the 
“aged ” and “adult ” specimens it belongs to the permanent and in the immature 
ones to the milk dentition. 
In a young female specimen taken from the pouch, and in which r‘ is just 
appeai’ing, there is also no trace of any third premolar. 
The animal is plentiful in and confined to the rocky ranges, not coming down 
on to the plains. It is very shy and remarkably agile in its movements amongst 
the rocks. 
Habitat ,—^It is not, as its popular name implies, by any means confined to 
West Australia, and is to be met with probably everywhere in the hill country of 
the central part of Australia. It is certainly to be found amongst the ranges of 
the central part drained by the Finke and Todd rivers and their tributaries, and 
was also secured liy the Elder Expedition in the Barrow Ranges. 
(4) Lagorchestes consficil/atiis, var. leichardti, Gould. The spectacled hare- 
wallaliy. 
Though far from uncommon, only one specimen of the continental variety of 
the spectacled hare-wallaby, known as Leichardt’s hare-wallaby, was caught. It 
was secured in a spring-trap at night amongst sandy country, close to a camp at 
the base of Mt. Sender in tlie McDonnell Ranges. It is apparently (Krefft) a 
solitary-living and nocturnal animal, and we never saw it about during the day¬ 
time. The fact that during the greater part of our time the thermometer fell at 
night to a very low temperature, often below freezing-point, will probably account 
for the fact that nocturnal animals were only rarely to be secured. Unfortunately 
the skull of the specimen was stolen one night from camp by a dingo, and for 
purposes of recognising the species only the skin remained. The following are the 
measurements of the skin, the bones having been left in the legs;—
