24 LLOYD'S NATURAL HISTORY. 
specimens of the latter sex are rare, the dogs generally stopping 
the progress of the rear-guard of ‘old men.’ In wet weather, 
when the chalky top-soil of the ‘malley scrub’ is softened, 
these Kangaroos are easily captured ; they sink deep into the 
ground, and any black-fellow’s cur, trained to such work, will 
stick to the tail of the Kangaroo until his master is able to 
come up and crack its skull or run a spear through it.” 
VI. OWEN’S KANGAROO. MACROPUS MAGNUS. 
Macropus (Boriogale) magnus, Owen, Phil. Trans., 1874, 
p. 247. 
Macropus magnus, Thomas, Cat. Marsup. Brit. Mus., p. 27 
(1888). 
Known only by a single skull in the British Museum from 
Northern Central Australia, distinguished from that of the 
preceding species by the small size or absence of the ledges 
on the front of the molar teeth, as well as by the longer 
foramina on the palate. There is a possibility that this Kan- 
garoo may eventually prove to be identical with the Isabelline 
Kangaroo, of which only a single skin was known when the 
British Museum “Catalogue of Marsupials” was written.

With this species we leave the true Kangaroos and come to 
the smaller animals forming the group of the Large Wallabies.
