blacker shade than on the rest of the fur prevails 
on the upper parts of the shoulders, extending over 
each side of the neck. The tail is at least equal 
to the whole length of the head and body, and is 
extremely full of long, soft fur, of a blacker cast

the whole is of a roundish or subcylindric form, 
but from the disposition of the long fur, has a 
slightly flattened appearance towards the ex- 
tremity. This species is most elegantly figured 
in Mr. White's Journal: and the representation 
here given is copied from the same plate, as was 
also the figure published some years past in the 
Naturalist's Miscellany, under the title of Petau- 
rus; it being then supposed that this animal had 
no abdominal pouch ; for which reason I at that 
time considered it as belonging to the tribe of 
flying squirrels, and separated them from the rest 
under a distinct genus of the above denomina-

The native name of this animal is Hepoona
