HALMATURUS RUFICOLLIS. 
Rufous-necked Wallaby. 
Head and Arms of both Sexes, of the size of life. 
An opinion exists among zoologists that the Halmaturus Bennetti, whieh is exelusively 
eonfined to Tasmania, and the H. ruficollis of the opposite portion of the Australian con- 
tinent, are one and the same species, and that the difference in the colouring of the two 
animals is merely the effect of climate ; the full-sized heads, then, which are given as 
accessories to the reduced figures on the succeeding Plate will be of value as illustrative 
of the difference in question. Certain it is, that aU the specimens from the continent 
(the H. ruficollis of this work and of previous authors) are much redder in colour, and 
have the white of the cheeks extending further on the breast, than the H. Bennetti 
procured in Tasmania. As these differences are carefully detailed on the succeeding 
page, it will not be necessary to enter into them here. 
The accompanying Illustration represents the head and forearms of both sexes, as near 
the size of life as possible.
