NOKTH GALLERY. 
[upper 
the right of this will be found portions of the skull and lower jaw, and 
the teeth of different specimens of the same species ; and to the left, 
extending to Case 8, are nearly all the more characteristic parts of the 
skeletons of various Iguanodons, chiefly from the Wealden formation 
at Til gate, and in the Isle of Wight. Tiiese specimens are mostly 
from the collection of the late Dr. Mantell. The remainder of the 
Case to the left (No. 8) is occupied by the remains of other gigantic 
reptiles from the Wealden and upper Oolitic formations, including the 
Megalosaurus and Cetiosaurus. On the right of the centre (Case No. 
10) are the Crocodilian remains ; among the specimens may be noticed 
the slender-snouted Crocodilians, in which the vertebrae are bi-concave, 
including the Teleosaurus Chaimianni, from the Lias of Whitby, and 
other Teleosauri from the Lias and Oolites of Germany and France. 
On the lower shelves will be found the remains of the Hylseosaurus, 
including the large block from Tilgate Forest, discovered by Dr. 
Mantell, which contains a considerable series of vertebraB, dermal 
spines, and other parts of this singular reptile. Among the Croco- 
dilians with the ordinary form of vertebrae, the body, or central part, 
being concave in front and convex behind, attention may be directed 
to the skull of the Crocodilus Toliapicus, mentioned by Cuvier as the 
" Crocodile de Sheppey," and a smaller Crocodile skull, which, like the 
last, is from the London Clay of Sheppey, and received the name of 
Crocodilus Spenceri from Dr. Bucldand. The most gigantic Crocodilian 
remains hitherto found are those from the Siwalik Hills, which are 
here arranged in the three divisions at the right hand of the Case ; 
they include both examples of the true Crocodiles, and of the long and 
slender-snouted Gavials. 
The Reptilian series is here interrupted by a collection of Bird re- 
mains, which occupy the Wall Case No. 11 at the end of the room. 
They are from New Zealand, and were found in a deposit which there 
are good grounds for regarding as of very recent origin. Part of the 
series was collected by Mr. Percy Earl, in the Middle Island, and the 
remainder by Mr. Walter Mantell in the North Island. These Bird 
remains are referred by Professor Owen to several species, and, indeed, 
to distinct genera of Birds, some of which are still living in New Zea- 
land, whilst others are, most probably, extinct. Amongst the living 
species may be noticed the Notornis Mantelli, a very large species of 
the Rail family. The first indication of this bird was given by some 
fragments of the skull found with remains of other birds, in super- 
ficial deposits of New Zealand, by Mr. W. Mantell. The living bird 
was subsequently discovered by Mr. Mantell in the middle island of 
New Zealand, and the specimen which he obtained is deposited in the 
Museum.* The greater portion of the bones, as determined by Pro- 
fessor Owen, belongs to a genus of birds to which the Professor has 
applied the name Dinornis : the birds of this genus were wingless, of 
large size, and some of gigantic proportions. The Dinornis giganteus 
(of which there are numerous parts of the skeleton in the collection) 
It will be found ia the Bird Gallery. — See Case No. 138."^
