NATURAL HISTORY. 
r NORTH 
the external appearance of certain orders of fishes combined with the 
internal organization belonging to the Saurian reptiles. The most 
striking specimens are the I. PlatyodGn in the central Case, and various 
bones of its gigantic variety on the top of the same Case and in Case 2, 
such as the head cut transversely to show the internal structure of the 
jaws; the carpal bones of one of the extremities, &c.: all from the 
lias of Lyme Regis—a new small species I. latifrons , in which the 
spiracle on the top of the head, between the eyes, claims particular no¬ 
tice, from Balderton in the county of Nottingham ■the splendid spe¬ 
cimens of P. intermedius, P. lonchiodon, P. communis , all from Lyme 
Regis ; the P. longvpinnis and P. longirostris from Whitby, &c. 
In the central passage between the Table Cases of these Rooms are 
placed various objects illustrative of particular mineral substances. One 
of the most interesting is a Table, presented by H. G. the Duke of 
Rutland, the slab of which is composed of a stalagmitical calcareous de¬ 
position, which was found investing the interior of a square wooden pipe 
in Blythe Lead Mine, Derbyshire. 
In the small Table Cases under the windows of Rooms II. and III. 
are temporarily deposited various mammalian remains, chiefly from the 
caverns of Eirkdake in Yorkshire, and from Kent’s Cavern, Devonshire, 
numerous remains of bears and of other animals from those of Gailen- 
reuth, in Franconia, ike. 
The Tables Cases in the two last rooms are at present occupied by 
various unarranged fossils, such as coralines, sponges, crinoidea, echiiio- 
dermata, shells, &c., together with a series of fishes of the chalk format 
tion from the Mantellian Collection. Several of these collections will 
be systematically arranged in Rooms V. and VI.
