RUFOUS-HAIRED HARK-KANGAROO.

tail is clothed throughout with short, stiff, mlpresscd hairs, 
scarcely hiding the scaly skin ; they are finely pencilled with 
black and rust colour at the base of the tail, but on the upper 
surface they soon assume an uniform brown black tint, which 
is continued to the point; on the under surface they are of a 
dirty pale rust colour, and towards the apex (about one inch 
from the point) is a naked scaly space of about an inch in 
length. The fur on the hack is very nearly black next the 
skin, but a considerable portion of each lmir is of a brownish 
rust colour; near the point the hairs are broadly annulated 
with white; and at the point, they are dusky or black. On 
the belly the fur is ashy grey next the skin.

The front incisor in L. hirsuttis is very large (very much 
larger than the others); as broad as the one next to it and 
half the third taken together. The second is a larger tooth 
than the third, being longer and broader at the base; but the 
third, which is very short in the vertical direction, is more 
dilated at the apex, and presents a strong oblique groove on 
the outer side. The second tooth also has a groove, but this 
is scarcely perceptible on the outer side of the tooth ; it 
truverscs the crown of the tooth in the longitudinal direction, 
and is deeply indented on the under part of die tooth. I did 
not see this groove in the second incisor in a female speci¬ 
men, which was perhaps older, and had the crown of die 
tooth more worn. This animal has a minute canine, which, 
when it was alive, could scarcely have penetrated the gum; 
it shows, however, in the skin, and is situated at die distance
