Murohisou District, Western Australia. The females are the specimens on which my 

 Macropus robustus cervinus was founded, the males, owing to an error in labelling, 

 having lieen thought to be ^f. rufiis, of which specimens were sent home at the 

 same time. For these males the name rertinus is unfortunately not very suitable, 

 as they are of a deep rich rufons, similar to, but richer than the ground colour 

 of J/, isabellinus. The head is of the same colour as the back, not markedly greyer, 

 as it is in the female; but the muzzle is inconspicnously browner. The hairs of the 

 ears are rufous, like those of the crown. In all, males and females, the fur of the 

 nape and fore-back slopes evenly backwards, there being no trace of a dividing 

 whorl in the regions of the withers. This is also the case in M. isabellinus. 

 The skull of the male, like that of the female, closely agrees with that of the true 

 M. robustus. 



A second set of four, two males and two females, obtained, like the previous 

 ones, through the kind agency of Mr. Woodward, are from the Grant Range, in the 

 Kimberley District, North-West Australia. These specimens, which could not be 

 distinguished from M. isabellinus until proper material of the latter form was 

 available, I now think to represent another very distinct subspecies of the robustus 

 group, and I have ventured to name it in honour of Mr. Woodward, to whose 

 assistance the Museum owes the whole of the material referred to in the present 

 paper. 



Macropus robustus woodward! sp. nov. 



Fur shorter, thinner, and harsher than in cercinus. Far of nape and fore-back 

 more or less reversed forwards from a dividing whorl situated on the withers. 



Male. — Bright rufous, nearly matching that of J/, isabellinus above throughout, 

 the head, ears, and back being all of this colour, as are also the middle line 

 of the tail pro.ximally, and the outer side of the limbs. Digits indistinctly 

 blackL-ih. Remainder of limbs and tail, and underside of body dull whitish. 



Female in general colour more or less fawn. Otherwise similar to male. 

 One of the two specimens is of a pale sandy fawn, the other a deep fawn like 

 the female of cervinus ; the former apjiears to be in summer, and the latter in 

 autumn or winter pelage. 



Skull similar in general characters to that of robustus, erubescens, and 

 cercinus, but a little smaller than any of them. 



Dimensions (approximate) of the male, taken from the dried skin : — 



Head and body, 1250 mm. ; tail, SOO ; hind-foot (s.n.) ; ear, 90.
