various remains of Reptiles, Birds, and Marsupial Mammalia. 
A series of Fossil Sponges from the Chalk, Green-sand, Oolitic, 
Devonian, and Silurian formations is displayed in the window recesses 
of this room. 
ROOM V. 
Here the Wall Cases are occupied by Mammalian remains. 
lu Case VI. are placed the Fossil Carnivora (the Cave-Lion, 
Hysena, Wolf, &c.). In Cases I. and II. are arranged (1) the re- 
mains of the Cave-Bear and other Ursidm; (2) the Cetaceans, Ziphius, 
Zeughdon, &c. ; (3) a large series of Hippoj^wtarni, remains of which 
are uncommon in England; the specimens in the Wall Case are 
chiefly from fresh-water formations in Italy, France and India. The 
existing Hippopotamus is restricted to the Continent of Africa. 
Cases III. to V. contain various other Pachyderms from England, 
France, Germany, Italy, and India. Remains of several species of 
Rhinoceros from each of these countries are exhibited, together with 
the Horse, Hippotheriiim, Tapir, PalcBotherium, Anoplotherium, Pig, 
&c. In Table Case No. 13 are arranged remains of several small 
Mammalia, including the Monkey, Bat, Beaver, &c. 
In the centre of this Room are skeletons of the male and female 
gigantic Irish Deer (Cervus megaceros), a series of antlers of which 
is placed on the Wall Cases, where are also exhibited a collection of 
skulls of Ruminants from India. 
In the Table Cases of the rooms Nos. V. and VI. are arranged the 
Fossil species of the Invertebrate classes (animals without back-bone), 
called Mollusca, Articulata, and Badiata. 
Corals (Zoophyta). In Table Cases 16 and 17, Room V., are ex- 
hibited a series of Tertiary and Cretaceous Corals, Oolitic corals, 
polished sections of "Madrepores," from the Devonshire marble; 
and Silurian Corals from Dudley, Gotland, and North America. The 
series is continued in Cases in the window recess, including fine 
examples of the " Chain-coral " brought home by the Arctic expedi- 
tion under Captain Kellett. 
A portion of Case 15 is occupied with the Polyzoa, horny coral- 
lines, most of which are found in the sea, encrusting shells and stones ; 
and which are now considered to be more nearly related to certain low 
forms of Mollusca (the Tunicata) than to the Zoophyta. 
The remainder of the Case is occupied with Nummulites {Fora- 
minifera); numerous examples are exhibited of these small chambered 
shells, which resemble Nautili and Ammonites in form, but are con- 
structed by creatures of a more simple organization. The larger sorts 
are most abundant in the Older Tertiary rocks (" Nummulitic lime- 
stone") of Europe, Africa, and India, — such as that of which the Great 
Pyramid is built. 
Two instructive series of enlarged models of these, for the most 
part, microscopic forms, are placed in this case : one series by M. 
D'Orbigny, the other by Drs. Reuss and Fritsch.
