EAST WING. 
some in section showing the extraordinary modification of the 
skull in adaptation to the sujDport of the heavy tusks and power- 
ful trunk. The series of elephants is continued in the pavilion 
at the end of the gallery, where skulls and skeletons of the 
African and Indian elephants are exhibited, among them a 
skeleton of a very large tuskless elephant or Mooknah. 
In the pavilion are also placed skeletons of the Sirenia or 
Sea-Cows, aquatic animals more nearly allied to the Ungulates 
than to the Whales with which they were associated in former 
times. Stuffed examples of these animals have also been 
placed here for want of space in the Mammalian Gallery. 
The majority of the cases on the right hand of the gallery 
are occupied by the Euminant Ungulata, such as the Camels, 
Oxen, Antelopes, Sheep, Goats and Deer ; cases 23 and 24 con- 
taining the 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.

Geound Eloor. 
Paiaeontoiogi- The ground floor of this wing consists, as on the other side of 
cal CollecUon. ^j^g 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.
