U5 
men here deposited of a species of plesiosaure, an ac¬ 
count and figure of which have been given in the Philo¬ 
sophical Transactions for 1719, by Mr. Stukely, who 
took it for a crocodile. A very perfect specimen, with 
head exhibiting the teeth, of the long-necked plesiosaure 
(Plesiosaurus dolichodeirus of Conybeare) from Lyme 
Regis; and another, apparently specifically distinct, 
plesiosaure (as likewise a cast of the same, with re¬ 
storations,) from Street in Somersetshire. 
As illustrative of the natural order of Chelonidae, we 
have some interesting specimens, chiefly from the isle 
of Sheppey. 
The only fossil species of the Batrachian reptiles in 
this collection is the gigantic Salamander, the subject 
of worthy Scheuchzer’s dissertation, Homo diluvii testis 
et theoscopos. Tiguri , 1726. 
The two upright Glass Cases of the western wall of 
the center compartment contain osseous remains (both 
original and as plaster casts) of the orders Edentata 
and Pachydermata. To the former of these the Me¬ 
gatherium (M. Cuverii) is generally referred, of which 
the casts here deposited, though constituting only a 
small portion of the whole skeleton, are sufficient to 
convey an idea of the considerable dimensions of this 
animal.—Among the specimens of the last mentioned 
natural order, may be specified the casts, chiefly of the 
lower jaw, of two species of that extraordinary genus 
the Deinotherium, lately discovered in Bavaria, some 
of the teeth of which were known to Cuvier, who sup¬ 
posed them to belong to gigantic tapirs;—jaws, tusks, 
molar teeth, and other osseous parts of the elephant 
(Elephas primigenins , Blumenb.), especially those of 
the Siberian variety, which is the Mammouth of early 
writers : a name erroneously transferred to the gigantic 
Mastodon (Mastodon okioticus). There are various 
species of this latter genus, the osseous remains of which 
are now under arrangement, together with those of se¬ 
veral species of Rhinoceros, Anoplotherium, Paleothe- 
rium, Tapir, &c.
