MACROPUS MAGISTER. 
At the time of founding this new species, De Vis went fully 
into the points of resemblance and difference of M. titan (Owen) 
and this form of extinct Kangaroo. The specimen from Balladonia 
consists of a fragment of the left lower jaw containing one perfect 
molar, presumably M2, and the stumps of the two anterior teeth ; 
the perfect tooth cannot be distinguished from the teeth M2 shown 
in figures 13 and 14, plate xxii., and figure 10, plate xxvi. of Phil. 
Trans., 1874, nor does it differ from several of the second molars of 
M. magister from Queensland, presented to this Museum by Mr. 
C. W. De Vis some thirteen years ago. The dimensions of the 
crown are 14.4 and 8.4; the crest of the hind lobe is somewhat 
worn, so that the tooth must have been in use for some time. The 
anterior talon has straight converging sides and a slightly sinuous, 
almost straight, anterior edge ; the lobes are thick, with rounded 
angles and rounded crests, having their convexity backwards ; the 
connecting links or bridges are slightly curved, the exterior face 
being concave. A vertical fold and a groove are present on the 
posterior aspect of the tooth. There is a bulging of the base and 
to erect plate. 
This is the first recorded specimen of this Queensland form for 
Western Australia. The fact that an undoubted M. titan was 
obtained in the Mammoth Cave in 1909 is of importance when 
considering the distribution of the two kindred species.
