by its long fur and peculiar pale body-colour, which latter indeed 

 seemed to be quite unique within the genus. 



Mr. Thomas also exhibited a Kangaroo which had been sent 

 to him from Western Australia by Mr. Bernard H. Woodward, 

 Curator of the Museum at Perth. 



Judging by its skull and more essential characters, it seemed to 

 be assignable to Macropus robustus, the Wallaroo, of which Mr. 

 Sclater's 31. erubescens was the South and Central Australian 

 representative. Its colour, however, was so different from either 

 the Eastern or Central forms of the species that Mr. Thomas 

 thought it necessary to distinguish it as a local subspecies, for 

 which he suggested the name Macropus robustus cervinus. 



With the exception of the head (which was greyish brown, much 

 as in M. r. lypicus), the whole of the upper surface was of a deep 

 rufous fawn, the hairs being of this colour to their bases. In both 

 M. r. typicus said M. erubescens the general colour was grey, the latter 

 being rufous across the shoulders. Tips of dorsal hairs black. 

 The chin, throat, and centre of the belly were whitish, not sharply 

 defined. The limbs also more whitish than the body, but darkening 

 to black on the tips of the fingers and toes. The tail was pale 

 sandy rufous, its extreme tip above black. 



The skull and dentition were apparently quite similar to those 

 of the true M. robustus, except that, in common with 31. erubescens, 

 the third upper incisor was less elongated. 



Hind-foot of type, without claw, 241 mm. 



Skull — basal length 128 mm.; greatest breadth 76*5; nasals 

 58 x 22 ; diastema (to p 3 ) 36 ; combined length of three anterior 

 grin ding-teeth 32 ; horizontal length of i 3 8*6, of p s 8. 



Hab. Pinda Station, Talgoo, Murchison District, Western 

 Australia. 



Type. Pemale (immature). B.M. No. 0.2.6.6. ; original number 

 1213. Killed 15th August 1899, by the Perth Museum collector. 

 Two specimens examined. 



Native name " Picquarda." 



With the specimens of Macropus r. cervinus, Mr. Woodward 

 had also sent several examples of the Eed Kangaroo (Macropus 

 rufus), a species which, when the Catalogue of Marsupials was 

 published, was not certainly known to inhabit Western Australia 1 . 

 These examples were also from the Murchison District, and seemed 

 to agree with the ordinary M. rufus of Eastern Australia, showing 

 no approximation to either M. isabellinus or M. magnus. 



Mr. Lydekker, on behalf of Mr. Eowland Ward, E.Z.S., exhibited 

 the horns and skin of a male specimen in the winter coat of 

 the Sheep which, on the evidence of specimens in the summer 

 dress, he had named Oris sairensis ('Wild Oxen, Sheep and Goats,'
