EAST WING. 
Edentata (Sloths, Anteaters, Armadilloes), the Marsupials or 
Pouched Mammalia, and finally the Monotremes of Australia 
(Ornithorhynchus and Echidna), which in their skeleton as 
well as other structures differ widely from the ordinary members 
of the class. 
Along the centre of the gallery is ranged a very complete 
series of skeletons of the wild cattle of the old and new world, 
and of the various species of Ehinoceros and Hippopotamus. 
A collection of horns of Oxen, Buffaloes, Antelopes and 
Sheep is placed on the top of the cases of the gallery and on 
the wall of the pavilion. 
EAST WING. 
Ground Eloor. 
Palaeontologi- The ground floor of this wing consists, as on the other side of 
cal CoUection. fj^^ building, of a gallery running west and east the whole length 
of the wing in front, of a smaller parallel gallery behind it, and 
leading from the latter, a series of galleries running north and 
south. The whole of this floor is occupied by the collection of 
the remains of animals and plants which flourished in geo- 
logical periods anterior to that in which we are now living. 
Some of these belong to species still existing upon the earth, 
but the great majority are extinct. They are arranged mainly 
upon zoological principles, that is, the forms which are believed 
to have natural affinities are placed together, but within some of 
the great divisions thus mapped out, especially of the Inverte- 
brata and plants, it has been found convenient to adopt a 
stratigraphical or even geographical grouping, the fossils of 
different geological formations being kept apart, and those of 
the British Isles separated from those of foreign localities. 
As this portion of the Museum is fully described in the 
Illustrated Guides* it will only be necessary to give a brief 
account of it here.
