 of the central digits. Tail short-haired, dull fawn, its base whitish below.

Skull, greatest length 175 mm., basal length 155; greatest breadth 91 ; nasals

 three ])Osterior cheek teeth, 37 mm. 



This fine Kangaroo, the representative of ^f. ruhnst/is in North Australia, is 

 most nearly allied to the South Australian crii/jesceiis, but it is duller-coloured, 

 both above and below, has fawn-colonred instead of blackish backs to its ears, and 

 has shorter fur. The type, as in M. r. woochvanli, has its nuchal hairs reversed, but 

 this character would seem to be inconstant.

" Caught in high granite ranges ; difficult to procure." 



Deceived by the peculiar Ueudrolagus-like look of this interesting black (or 

 rather chocolate-coloured) Kangaroo, Mr. Rotlischiid formed a special genus for 

 its reception ; but he has since rightly recognised that it should be considered a 

 member of the genus Macropus. 



It is, however, none the less a most striking and remarkable discovery, the 

 finest that has been made in Australia for many years, and the organisers of 

 Mr. Tunney's expedition are to be congratulated on so valuable a result. 



The skull of M. bernardus is very like tliat of M. robustiis ; it is, however, 

 smaller, more lightly built, and notably lower in side view, the height of the 

 muzzle at the diastema and of the brain-case and pterygoids being both markedly 

 less. The posterior nares are in consequence also much lower. The nasal notch 

 is somewhat deeper, the overhang of the nasals being about 15 mm., as against 

 11 mm. in the larger skull of robi(stus. 



The dentition is quite normal, and the diagnostic teeth P and the premolar 

 are of the dimensions and strnctnre of those of M. robustus. 



The measurements of an adult male skull are as follows : — 



Greatest length, 153 ; basal length, 139 ; greatest breadth, 85 ; nasals, length, 

 64, breadth behind, 24 ; constriction, 17 ; diastema, 31 ; palate length, 95; length 

 of jialatal foramina, 9: height of muzzle at anterior end of premolar, 26; height 

 of posterior narial opening-, 14 mm.

 three anterior molariform teeth, 32 mm.
