berg; the small L . papyraceus , from the lignite called paper coal, of 
Bonn and Bareuth, to which species also the impressions in semiopal, 
from Bohemia, appear to belong. 
Among the Esocids or pikes, (Cases 24 to 27,) the tine suite of 
specimens of Esox lepidotus from Oeningen deserve particular notice, 
as likewise the large Sphenolepis squamosseus, from Aix, in Provence, 
and the Sphenolepis Cuvieri, of very rare occurrence in the gypsum 
of Montmartre, and named after its illustrious discoverer, by whom it 
was first noticed, in his Recherches sur les Ossem,ens fossiles. 
The Halecoids, (Cases 25 to 27, middle,) or Herrings, (a family con- 
sisting of Cuvier’s Clupese and Salmonidse, but which have lately 
undergone still further subdivision,) begin with the chalk, and 
are frequent in more recent formations: of those of the former 
may be mentioned the Clupea Scheuchzeri , megaptera , &c., from 
the slate of Glaris; and, above all, the considerable suite of spe- 
cimens (many of them figured in Agassiz’s work) of Osmeroides, first 
described as Salmo Lewesiensis by Dr. Man tell, by whom they were 
obtained from the quarries in the immediate vicinity of Lewes, and most 
successfully extricated from the chalk ; — from the same locality, and 
likewise from the Mantellian collection, are the almost unique specimens 
of Acrognathus Boops and of Aulolepis typus, figured and provision- 
ally placed with the Halecoids in the same work. To these are added 
specimens of the singularly preserved angmarset, ( Salino Groenlandicus 
of Bloch, Mailotus villosus of Cuvier,) which occur in the shape of 
slender nodules or hard argillaceous mummies, at the Sukkertop, on 
the West Coast of Greenland ; being perhaps the only instance of 
identity of a fossil with a recent species of fish. 
Of the two last families of this order of Cycloids, the Anguilliform 
and the Gadoids , no well determined species are extant in the collec- 
tion, except perhaps, of the former, a species or two of Anguilla , from 
Oeningen ; and of the latter, the head of Arnpheristus toliapicus, from 
Sheppey. 
The Table Cases on the N. side of the Room are at present occu- 
pied by various unarranged fossils, such as corallines, sponges, crinoidea, 
echinodermata, shells, &c. : these will hereafter be systematically ar- 
ranged in this Room, and in Room VI. 
The Wall Case at the East end of the Room is occupied by the 
remains of ruminant mammalia. The most conspicuous specimen in 
the Case is the skull of the Sivatherium, from the Sewalik Hills, 
presented by Major Cautlev. 
The Wall Case at the West end of the Room contains remains of 
various species of Rhinoceros, amongst which are a fine series of teeth, 
and other parts of the two species found in this country — the Rhinoceros 
tichorhinus , and R. leptorhinus ; most of these specimens are from the 
Pleistocene freshwater deposits of Essex. 
In the centre of the Room is a complete skeleton of the large extinct 
elk, bones of which 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.
