This beautiful species was procured in the interior of W. Australia. 
It is nearly allied to P. penicillata, but is of smaller size and has 
the tail less bushy; the portion covered with short hair is extended 
from the base nearly to the middle of the tail, and is remarkable 
for its brilliant rusty-red colour; on the apical half of the tail the 
hairs are long, being on an average about half an inch in length ; 
all the under side is black, very nearly to the root. The fur is 
soft and moderately long, and its general colour is ashy grey ex¬ 
ternally, but grey next the skin; the under parts of the body are 
white, tinted with cream-colour, and this last-mentioned tint is 
very distinct on the sides of the body; the eye is encircled by a 
narrow black line, and there is a blackish patch in front of the 
eye. The ears are large and very sparingly clothed for the most 
part with very minute dusky hairs, but at the base, both exter¬ 
nally and internally, are some longish yellow hairs.

ON THE RUDIMENTAL MARSUPIAL BONES IN THE 
THYLACINUS. By Professor Owen. 
(From the Proceedings of the Zoological Society, December 12, 1843.) 
The marsupial bones, as bones, do not exist in the Dog-headed 
Opossum or Hyeena of the Tasmanian colonists (Thylacinus 
Harrisii , Temm.); they are represented by two small, oblong, 
flattened fibro-cartilages, imbedded in the internal pillars of the 
abdominal rings, and appear each as a thickened part of the 
tendon of the external oblique abdominal muscle, which forms 
the above pillar. The length of the marsupial fibro-cartilage is 
six lines, its breadth from three to four lines, its thickness one 
line and a half.
