﻿THE DORCA KANGAROOS. 57 



Dorcopsis chalmersi^ etZ>. beccaru, Mikl. Macl., Proc. Linn. Soc 

 N. South Wales, vol. ix., p. 569 (1884), vol. x., p. 146 

 (1885). 



Characters. — Smaller than the last, with the soft and thicTc fur 

 longer; hair of neck reversed. General colour dark smoky- 

 grey, of variable shade ; chin brown ; under-parts grey or 

 greyish-white. Face dark grey, with a faint pale cheek-stripe ; 

 ears larger than m D. miielleri, with their back thinly haired 

 and not darker than the crown. No hip-stripe ; limbs dark 

 smoky-grey ; tail shorter than body, dark brown, with the tip 

 white and naked. 



DistrilDiition. — Eastern and South-eastern New Guinea. 



Curiously enough, this species presents the same superficial 

 resemblance to Macropus browni as is shown by D. muelkri to 

 M. brunii. Whether these resemblances are examples of mimi- 

 cry, and if so on which side the mimicry exists, and what may 

 be its object, is at present quite unknown. 



III. MACLEAY's DORCA. DORCOPSIS MACLEAYI. 



Dorcopsis inackayi, Mikl. Macl, Proc. Linn. Soc. N. South 

 Wales, vol. x., p. 149 (1885) ; Thomas, Cat. Marsup. Brit. 

 Mus., p. 92 (1888). 



Characters. — The smallest form. Fur radiating from two centres 

 on back of neck. General colour brownish-grey, becoming 

 somewhat lighter on the under-parts ; tip of tail white and 

 nearly naked. 



Distrihution. — Southern New Guinea. 



As the single specimen on which this species was established 

 presents many features connecting the typical representative 

 of the genus with Macropus, it has been suggested that it may 

 turn out to be a hybrid between J/, broivni and D. luciuosa.
