THE MUSK-KANGAROOS. GENUS HYPSIPRYMNODON. 
LTypsiprymnodon, Ramsay, Proc. Linn. Soc., N. South Wales, 
wal, 1, Dp: 33: (1876). 
The third and last sub-family (ypsiprymnodontine) of the 
Macropodide is represented solely by the remarkable creature 
known, from its strong scent, as the Musk-Kangaroo, which 
forms a connecting link between the present and following 
families. Indeed, it is somewhat difficult to decide to which 
of the two the species ought to be assigned, although the 
presence of a large pocket-like pit on the outer side of the 
hinder part of the lower jaw seems to be indicative of closer 
affinity with the Macropfodide than with the Phalangeride. 
The following are the distinctive features by which the sub- 
family differs from the two other equivalent groups :— 
Claws small, weak, and of nearly equal size ; first toe of hind 
foot well-developed and opposable to the others ; tail naked 
and scaly. Last premolar set obliquely to the line of the 
molars. 
The undermentioned characters, on the other hand, may be 
regarded rather as distinctive of the one genus Aypsiprym- 
nodon. 
Size very small; form Rat-like; nose entirely naked; ears 
large, thin, and devoid of hair ; limbs of sub-equal length, and 
adapted for walking ; first toe of hind foot long and clawless ; 
fourth toe of same not disproportionately larger than the other ; 
the fifth and united second and third being alike well de- 
veloped ; tail cylindrical and tapering, haired only at the 
root.
