FOSSIL FISHES AND OEPHALOPODS.

members of the group, some far exceeding any existing ostrich, 
while others are 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 
Eoc (JEpyornis) from Madagascar, in the south-east corner of 
the room. The skull and certain other remains of large extinct 
birds from Patagonia are also shown in this room. These 
birds appear to have been allied to the existing South American 
Ceriama. 
The long gallery north of the mammalian saloon contains a Extinct 
fine assemblage of Eeptilian remains. The south side is de- ^^P^^^^- 
voted to the G-reat Sea-Lizards (Plesiosauria and Ichthyosauria), 
mostly from the Lias formation. Two nearly perfect skeletons 
of Plesiosaurians from the Oxford Clay are mounted in cases 
in this gallery. Kanged 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 Bernissart 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 Ornithosauria, or Flying 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, which also occurs in 
Eussia. 
Of the galleries running northwards from this, the one nearest Fossil 
the centre of the building is devoted to the collection of Fossil J}^\^^, 
Fishes. The next contains the Cephalopods, a group of molluscs 
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 Extinct 
gallery contains the remaining Molluscs and Brachiopods ; the ^^^^Jj^^^^^®' 
Echinoderms, Annelids and Crustacea; the fourth, the Corals, 
Sponges, Protozoa, and Fossil Plants. In these last two
