The differences in cranial dimensions are, of course, not very great, but as the 
measurements quoted above have been obtained from old specimens of the Phalanger 
from the Cape York Peninsula with obsolete sutures and well worn teeth they appear 
to indicate the maximum size of that race. 
Two small and young specimens collected at the same locality are also very 
pale, one might be termed light smoke grey, the other silvery grey overlaid with 
the blackish tips of the longest hairs; both have the outer two thirds of the tail 
black and are white below. 
All four specimens, two old and two young have been collected at Olen Creek, 
between Coleman- and Mitchell rivers, Cape York Peninsula, ?/9 and "/» 1913 in open 
forest land and a quite »wild country». They are said to sleep over the day in hollow 
trees. 
The Common Phalanger is according to the literature not to be found on the 
Cape York Peninsula. 
Trichosurus vulpecula johnstoni Ramsay. 2 specimens from the »>rain forest 
jungles» at Cedar Creek ”/a 1913. 
»Rests during day-time in the big hollow trees and appears to live chiefly in 
the crowns of the trees where it moves with dexterity from a crown to another. 
Very fierce and tries to defend itself.» 
Trichosurus caninus OGILBY. 1 specimen (no skull) in the rain forests, Tam- 
bourine, S. Queensland, ”"/120 1912. 
Perameles obesula SHaw. 1 specimen from Olen Creek between Coleman and 
Mitchell Riwer, Cape York Peninsula, 2 Sept. 1913.
