Havre lately had an opportunity of consulting Schreber’s ‘‘ Saugthiere,” I find therem the figure of an

; animal so nearly resembling my Perameles arenaria, that I am induced to believe it to be the same species ;

$ I have consequently, in justice to the first describer, Dr. Wagner, placed my own name as a synonym
° to his.

Dr. Wagner, whose labours display great care and no ordinary extent of information, has very accurately

pointed out the distinctions between it and the P. fasciata, the most nearly allied species yet discovered ;

! ; but as he has not mentioned the habitat of the animal he has described, I am unable to come to a positive

\ conclusion on the subject: if it be from Western Australia, it is doubtless identical with the one here figured.

The present animal inhabits the whole line of coast of the Swan River colony, but, so far as I can learn,

\ is not found to the westward of the Darling range of hills. It resides in the densest scrub, thickets of the

seedling Casuarineé being its favourite resort. It makes a compact nest in a hollow on the ground, of

grasses and other materials, which assimilate so closely in colour and appearance to the surrounding

é herbage, that it is very difficult of detection, the difficulty beg much increased by there being no visible
mt opening for the ingress and egress of the animals. The nest is generally inhabited by pairs. The young 2
are either three or four in number. 5
Its food consists of insects, seeds and grain. It excavates holes in the earth with rapidity and ease, and 1

to these and the hollow trunks of fallen trees it flies for shelter when pursued by its natural enemies. y
Mr. Gilbert remarks that this species is, without exception, the most difficult to skin of all the marsupials | °

The sexes are alike in colour, but when adult the female is smaller than the male. Examples are fre- a
quently seen of all sizes, which appears to be solely occasioned by a difference of age. Fi
The fur is harsh to the touch, and of a greyish brown hue, interspersed with numerous long black hairs, >
