EAST WING. 
preserved in the specimen. A series of skeletons of the " Moa," 
or Dinornis of New Zealand, a bird in which no trace of a 
wing has been discovered, show the diversity of size of different 
members of the group, some far exceeding any existing ostrich 
and others scarcely larger than a good-sized turkey. Some 
of these remains are so recent as still to be covered with dried 
skin, and even feathers. Several eggs are also shown ; but, large 
as these are, they are greatly exceeded in size by those of the 
iEpyornis from Madagascar, in the south-east corner of the 
room. 
Extinct The long gallery north of the mammalian saloon contains a 
Beptiles. frQg assemblage of Eeptilian remains. The south side is devoted 
to the Great Sea-Lizards (Plesiosauria and Ichthyosauria) , 
mostly from the Lias formation. Eanged in the cases on the 
north side are remains of the gigantic Dinosauria, which far 
exceeded in size any other land-animals. A mounted plaster 
cast of a complete skeleton of an Iguanodon, found (with many 
others) at Bernisart in Belgium, is a conspicuous object in the 
middle of the room. The original from which it was taken is 
in the Brussels Natural History Museum. At the eastern end 
of the gallery are the Pterosauria, or Plying Eeptiles. At the 
west end is the nearly complete skeleton of Pariasaurus from 
the Karoo formation (Trias) of South Africa, one of the most 
remarkable fossil reptiles yet obtained. 
Extinct Of the galleries running northwards from this, the one nearest 
Pishes. th e centre of the building is devoted to the collection of fossil 
Fishes, an account of which has been published in a special 
guide.* The next contains the Cephalopods, a group of animals 
abounding in extinct forms, of which the Belemnites and 
Ammonites are the best known. The form and structure of 
their nearest living representatives, the various species of Cuttle- 
fishes, Squids, Argonauts and Nautilus are illustrated by models 
and drawings and specimens, placed near the entrance of the 
gallery and along the top-line of the wall-cases. The third 
gallery contains the remaining Molluscs and Brachiopods ; the 
invertebrates Echinoderms, Annelids and Crustacea; the fourth, the Corals, 
and Plants. Sponges, Protozoa, and Fossil Plants. In these last two
