70 NATURAL HISTORY. (Fossils.) [NORTH 
Van Diemen’s Land, presented by Mrs. Howley, the lady of His Grace 
the Archbishop of Canterbury. 
In this room are also placed two geological models, by the late 
Mr. Elias Hull; one representing part of the High Peak of Derby¬ 
shire ; the other, the lake district of Cumberland, Westmoreland, and 
Lancashire. 
Room II. 
In the Wall Cases of Room II. are various mammalian remains, 
amongst which are numerous parts of the Megatherium, from Buenos 
Ayres : these will ultimately be removed to Room VI., where many of 
the specimens formerly in these cases are now deposited. In Case V. 
are arranged the portions of the carapace and other parts of the gigan¬ 
tic fossil tortoise ( Megalochelys Atlas ) discovered by Major Cautley, 
Bengal Artillery, in the Sewalik Hills, and formed part of the very ex¬ 
tensive collection presented by that gentleman to the Museum. On the 
upper shelf in Case III. are arranged the bones of various species of 
J Dinornis, an extinct genus of birds, which formerly inhabited New 
Zealand—some of these bones, it will be seen, must have belonged to 
birds of most gigantic dimensions. In the Table Cases under the 
windows of this and the next room are temporarily deposited some 
mammalian remains; and the north-east Wall Case is filled with 
Crinoids, Star-fishes, &c. 
Room III. 
The Wall Cases 1 to 4 are set apart for the Batrachian, the Chelonian 
and Emydosaurian reptiles, now under arrangement. To the first 
named of these orders belongs the gigantic Salamander, the sub¬ 
ject of Scheuchzer’s dissertation, Homo diluvii testis et theoscopos. 
Various specimens illustrative of the Chelonians will also be placed 
in some of the Wall Cases of Room II. Among the specimens 
of the third of these orders may be specified the Crocodilian 
division, containing very interesting objects, such as specimens of 
the head, with other bones, of the gavial (or rather gharial) of 
Whitby ( Teleosaurus Chapmanni ), which, though correctly deter¬ 
mined by its discoverer, Capt. V/. Chapman, and also by Wooller 
(Phil. Trans, for 1758), was subsequently mistaken for a species of 
Ichthyosaurus ;—another species of gharial (considered a distinct genus, 
bearing the name of JEolodon) from the lias at Monheim in Franconia, 
being the unique specimen described and figured by Soemmerring in 
the Memoirs of the Academy of Munich, under the name of Crocodilus 
priscus; —ahead of Crocodilus Toliapicus, mentioned by Cuvier as Cro- 
codile de Skeppey , and which appears to be distinct from Crocodilus 
Spenceri , of which the original specimen is likewise deposited here; 
—the head and other parts of the Geosaurus (the Lacerta gicjantea 
of Soemmerring) found together with the preceding, and figured 
and described by the last-mentioned naturalist in the Transactions 
of the Academy of Munich^—the interesting groups embedded in two 
slabs of limestone of the well known Swanage Crocodile (a distinct 
genus) and one of the principal specimens of the Mantellian collection ; 
—the low T er jaw and other parts of the cranium, vertebrae, &c., of the 
huge reptile ( Mososaurus Sancti Petri) from the St. Peteps Mountain 
near Maestricht, presented, in 1784, by the celebrated Peter Camper,
