The individual variation of Macropus skulls make a direct comparison neces- 
sary for making out differences. Two skulls of M. agilis aurescens and two from 
Dampier land have thus been selected. All four are males in which the last molar 
is just cutting the gum, and they correspond in size as well as in age two and two.

The differences thus recorded are not very important, but as they are con- 
stantly present in the whole series of specimens from Dampier land it appears correct 
to distinguish the agile Wallaby of that country as a different subspecies. 
M. a. jardinez from Northern Queensland is also said to be speckled with black, 
but its ground colour is said to be »light yellowish sandy» (ScHWARZzZ l. c. p. 165), 
and thus probably lighter than that of the Wallabies from Dampier land. As M. a. 
aurescens occupies the intervening country I cannot for the present identify these 
two forms from Northeastern and Northwestern Australia. 
Lagorchestes sp.? — 1 young specimen »found with its mother in a nest in a 
thick tussock of Triodia ”"/2 1911 St. George Range, Kimberley». As the mother 
escaped, and the skull of the young was lost, the specimen cannot be determined 
with certainty, but the whitish tail makes it probable that it represents L. conspi- 
cillatus leichardti.

[Trichosurus sp. — A young specimen from the »>rain forest» of Blackal Range, 
S. Queensland, obtained "5/0 1911. The specimen is too young to be identified. At 
some distance it appears almost entirely black above, because the long hairs are 
shiny black, and the thick underfur is dark grey. Some few of the long hairs have 
light rings, and the underfur has partly light tips, or subterminal rings visible at a 
eloser inspection, so that the animal, although very dark is grizzled on the sides and 
fore quarters. Inside of ears white. The whole of the underside is chamois (between 
325,1 and 325,2 Rép. de Coul.). Feet and tail black, the latter is well furred to the 
tip. The fur is terminally 8 mm., at the middle of the tail about 11 mm.]
