rest (the Plioca Falklandica* of Shaw), by the want of the 
woolly substance under the hair, (called fur by the seal- 
fishers,) and by the length of the ear, which in the latter 
species, described by Shaw, is long and awl-shaped. 
. Captain King m his MS. observes, that this seal is found 
at Rottnest Island on the West Coast, and at King George 
the Third’s Sound. It appeared also to be the same species 
that frequents Shark’s Bay; and, if it is M. Peron’s Otaria 
cinereay it is also found as far to the eastward as Kangaroo 
Island. 
The head is deposited in the Linnean Society’s collection.

Opossum Mouse, Colonists at Port Jackson. 
This little animal, the smallest and most beautiful of the 
opossum tribe, is exceedingly numerous in the vicinity of 
Port Jackson. It was first described by Dr. Shaw in his 
Zoology of New Holland. There are several specimens in 
the Linnean Society’s collection. The above is placed in 
the British Museum. 
* The specimen in the Museum, which I take for this species, 
was brought by Captain Peake from New South Shetland: it 
differs from Pennant’s, and consequently from all succeeding de- 
scriptions that are taken from him, in having five instead of four 
claws and toes to the hind foot.
