hinder part whitish yellow: a brandish dusky band crosses 
the hinder part of the back. 
Inhabits the Swan River district, Western Australia, and the 
neighbourhood of King George’s Sound. 
The present animal has received the name of the Saddle- 
backed Perameles from Mr. Gould, on accouut of its having 
a large and nearly circular area on the back, which is of a 
darker hue than other parts, if we except the transverse band 
which crosses the lumbar region, u little in front of the hind 
leg: with respect to this dusky patch, it must be remarked, 
however, that it is extremely indistinct, and it appears to me 
that it would be more accurate to describe the animal as 
having a crescent-shaped band, of a rather paler laic than the 
ground-colour of the back, immediately in front of the dark 
band on the lumbar region ; this pale band, which corre¬ 
sponds to the foremost of the bands in P .fasciata orP. Gun tut, 
combined with the sides of the body being paler than the 
other parts, causes the appearance of the dark area re¬ 
ferred to. 
The under fur in P. myosuros is unusually plentiful, 
especially on the hinder parts of the back, and is of a whitish 
grey colour ; the longer flattened, harsh hairs, are grey- 
white at the root, and rusty yellow near or at the point; on 
the hack are many which are black at the point, and these 
produce the darker general hue of that port: on the under 
parts of the body the hairs are uniform to the root, white, 
but slightly suffused with yellow ; the feet and tail are of the 
same colour, hut the small hairs on the upper surface of the 
hitter are partly yellowish, but chiefly black. The ears art* 
rather long, very broad at the base, and rather suddenly con¬ 
tracted at the apical portion ; their hinder edge is somewhat 
emarginated; on the inner side they have pale yellow hairs, 
and externally they are clothed with minute hairs of the same
