alian Museum. It may also be M. Desmarest's; if
this is so, the latter name will have to be adopted, and the one first
used erased from the list.

Number 47.

The Macropi with hairy muffles are found in grassy places, while the
Halmaturi are confined to the scrubs; and the Petrogalae, or
Rock-Kangaroos, to the rocky districts; the latter, like Bettongia, sit
with their tail between the legs. Mr. Gould informs me the animals of the
latter genus also use their tails for the purpose of carrying the grass
to their nests. The tree Kangaroos of New Guinea have a tail somewhat
like a squirrel. These differences of habit show the propriety of
dividing this group of animals into genera.

Number 48. Macropus laniger.

This name must be rejected as the animal is not wool-bearing. The skin in
the Paris Museum is made up with the skin of a sheep. M. Desmarest's
description of the female M. rufogriseus in the New Dictionary, very
nearly agrees with this species, but Mr. Gould is inclined to consider
the specimen he was shown for that species in the Paris Museum was M.
major.

Number 57. Halmaturus elegans.

The description of Mr. Lambert is so short that it has hitherto been
considered impossible to determine it with accuracy; but on comparing the
coloured plate which is bound up with Sir Joseph Banks' copy of the
volume of the Transactions containing the paper, now in the Museum
Library, with the specimens of kangaroos in the Museum collection, I have
very little doubt of its being intended for one which Mr. Gould considers
as identical with M. ruficollis of M. Desmarest. M. Desmarest's animal is
said to come from King's Island, in Bass Strait, while Mr. Gould's
animal, like the one Mr. Lambert described, is from New South Wales. Mr.
Gunn remarks that H. billardieri is common in the locality indicated by
M. Desmarest.

Number 67. Petrogale brachyotis.

This species was discovered by Captain G. Grey, in his expedition, and
the specimens he collected he gave to Mr. Gould, who described them, and
is now about to figure them in his forthcoming monograph of the species
of kangaroos: a work which will be as far superior to any other published
on Mammalia in beauty of design and accuracy in the execution of the
plates as his work on Birds has been to any that has hitherto appeared
either in England or on the Continent. The specimens are now in the
collection of the British Museum.

Number 84. Mus lutreola.
