The animal is especially remarkable, inasmuch as, although it belongs 
to the Lizard tribe, it possessed but two teeth, and these in the form 
of large tusks, descending nearly vertically from the upper jaw. Here 
are also placed various Batrachian remains from the Coal-measures, 
the Trias, and Tertiary formations, among which may be specially 
mentioned the head of Belodon Kapffii from Stuttgardt, and the 
gigantic Salamander from (Eningen (better known as the "Homo 
JDiluvii testis" of Scheuchzer). 
At the end of the Case are placed various bones of the skeleton and 
parts of the shell of the enormous Tortoise from India, of which a 
restored model will be found in the Lobby to Room No. I. 
In Case 3 are the remainder of the Fossil Tortoises and Turtles ; 
and in Cases 4, 5, and 6, commences the series of the large Sea-reptiles 
(Enaliosaueia). They present two well-marked modifications of struc- 
ture — the Plesiosauri, in which the neck is long and the head small, 
and which are arranged in this room ; and the Ichthyosauri and Plio- 
sauri, in which the head is large, and joined to the body by a very 
short neck. 
On the Wall Cases 4-6, 8, and 9, are arranged fine examples of this 
group, including Plesiosaurus dolichodeirus, and rostratus, and a fine 
head of Pliosaurits grandis (the teeth of this latter are placed in Wall 
Case 5). 
The Wall Case No. 7, at the end of the room, contains Mammalian 
remains of the Ruminant tribe from the Siwalik Hills and other parts 
of India. 
ROOM IV. 
Here the series of Reptilian remains is continued, by the Sea-rep- 
tiles already alluded to in the account of the preceding room, the 
Ichthyosauri occupying the Wall Cases 1-5. In Wall Cases 6 and 7 
is continued the suite of Mammalian remains belonging to the order 
Ruminantia; Case 6 contains the Cervine remains, and Case 7 the 
Bovine, the heads and antlers being placed on the top of the Cases. 
In a series of small Table Cases beneath the windows are placed 
various remains of Reptiles, Birds, and Marsupials : Case No. 12 con- 
tains the remarkable long-tailed Bird from Solenhofen (the Archaop- 
teryx macrura of Prof. Owen). The bones of the wings, the blade- 
bone and furculum, or "merry-thought," the bones of the legs and 
feet, are those of the bird-class ; but the tail is long and many-jointed, 
with a pair of feathers to each joint ; these and the quill feathers and 
" under-coverts" of the wings are beautifully exemplified by impres- 
sions left in the peculiarly fine-grained "lithographic" limestone in 
which this unique specimen of a bird of the Oolitic or Mesozoic 
period has been fossilized. A series of Fossil Sponges from the Chalk 
and Green-sand formations is displayed in one of the window recesses 
of this room.
