GALLERY.] NATURAL HISTORY. 
nominated on account of their having in a recent state clearly presented 
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. Platyodon 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 stimcture 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 w'hich the 
spiracle on the top of the head, between the eyes, claims particular no¬ 
tice, from Balderton in the county of Nottingham, presented by Dr. 
Bland ;—the splendid specimens of P. intermedins, P. lonchiodon, P. 
communis, all from Lyme Regis; the P. longipinnis and P. longiros^ 
tris 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 TIL 
are temporarily deposited various mammalian remains, chiefly from the 
caverns of Kirkdake in Yorkshire, and from Kent’s Cavern, Devonshire, 
numerous remains of bears and of other animals from those of Gailen- 
reuth, in Franconia, &c. 
The Table Cases in the two last rooms are at present occupied by 
various unarranged fossils, such as corallines, sponges, crinoidea, echino- 
dermata, shells, &c., together with a series of fishes of the chalk forma¬ 
tion from the Mantellian Collection. Several of these collections will 
be systematically arranged in Rooms V. and VI. 
In the centre of Room V. is a complete skeleton of the large extinct 
elk, bones of vdiich are so frequently met with in the bogs of Ireland, 
and which is occasionally found in some parts of England, and in 
the Isle of Man. The present specimen is from the first mentioned 
locality : it is the Cervus megaceros and C. giganteus of authors. 
Room VI. is devoted chiefly to the osseous remains of the Pachy- 
dermata and Edentata, which are at present under arrangement. Among 
the more prominent specimens of the collection may be particularized 
the skeleton of the American Mastodon {Mastodon Ohioticus), and 
suite of separate bones and teeth of the same animali-the jaws, tusks, 
molar teeth and other osseous parts of Elephas primigenius, Blumenb., 
especially those of the Siberian variety, (the Mammoth of early writers) ; 
the crania and other parts of extinct Indian elephants which form 
portion of the highly valuable collection presented by Capt. Cautley, 
Bengal Artillery, to whose.indefatigable exertions science is indebted 
for the formation of a rich assemblage of fossil remains obtained in the 
Siwalic, or Sub-Himalayan ridge, situated between the Jumna and Sutliy 
rivers. From this same collection are the two very perfect skulls of a Mas¬ 
todon, regarded as distinct from other species of that genus hitherto 
noticed or described. The casts of the skull and other parts of the 
Deinotherium, a most gigantic quadruped found at Eppelsheim, forty 
miles N. W. of Darmstadt, will also be placed in this Room, as well as 
the remains of Edentata, including those of the Megatherium, and
