near the avIdcIows at the ends of the room are devoted to the Fossil 
species of Hippopotamus and Rhinoceros. 
Remains of two kinds of Rhinoceros, both with two horns, have been 
discovered in the newer tertiary deposits of England : one of these, 
called RJiinoceros leptorhinns, in lacustrine beds, associated with re-, 
mains of an extinct Elephant, differing from the Mammoth ; the 
other, and more common species, is the Wiinoceros ticliorliinus, the re- 
mains of which occur in later drift formations, and in caverns, associ- 
ated with those of the Mammoth, large Oxen, Deer, Bears, and Wolves. 
Remains of the Hippopotamus are less common 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. 
In the Table Cases of the rooms Nos. V. and VL are arranged the 
Fossil species of the Invertebrate classes (animals without back-bone), 
called Mollusca, Articulata, and Piadiata. 
Corals {Zoophyta). In Table Case 8, of Room VI. are exhibited 
a series of Oolitic corals, chiefly from Steeple-Ashton, Wilts ; polished 
sections of " Madrepores," from the Devonshire marble ; and Silurian 
Corals from Dudley and North America, including fine examples of 
the " Chain-coral " brought home by the Arctic expedition under Cap- 
tain Kellett. 
NuMMULiTEs [Foraminifera). A Table Case (No. 17) in the window 
of Room V. contains numerous examples of these small chambered 
shells, resembling Nautili and Ammonites in form, but constructed by 
creatures of a more simple organization. The larger sorts are most 
abundant in the Older Tertiary rocks (" Nummulite limestone") of 
Europe, Africa, and India, such as that of wdiich the Great Pyramid is 
built. 
Sea-urchins (EcliinidcB). Case 7, Room VI. These are arranged 
in four principal groups. 1. Those from the Tertiary strata, of which 
the most remarkable are the large Clypeasters from Malta. 2. The 
Chalk Echinidm, amongst which are the Helmet-urchins {Ananchytes), 
popularly known as "fairy-loaves;" the Heart-urchins [Spatangidce), 
called " fair3^-hearts ;" and numerous species of Cidaris, provincially 
termed " shepherd's crowns ;" some of the specimens have spines 
still attached to the shell. 3. The Jurassic or OoMiio, EchinidcB, and 
the Sea-urchins from the Trias and older rocks, which include many 
singular forms of the spines or locomotive organs. 
Fossil Insects, Crabs and Lobsters [Articulata). Table Case 
No. 12, Room VI. The Insect remains consist of the wing-covers 
{elytra) of beetles from the Oolitic strata of Purbeck and Stonesfield, 
and Dragon-flies (some in their larval state), from Solenhofen and 
Gilningen. There is also the wing of a large flying insect, resembling 
the living Corydalis of the United States, in a nodule of clay-ironstone 
from Coal brook Dale. 
Fossil insects may be seen in some of the specimens of amber in 
the Table Case No. 00, Room I. 
The Crabs and liobsters in the Table Case No. 12, are chiefly from
