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 Aulolepis txjpus , figured, and provision¬ 
ally placed with the Halecoids, in the same work. To these are added 
specimens of the singularly-preserved angmarset, (Salmo Grcenlandicus 
of Bloch, Mallotus villosus of Cuvier,) which occur in the shape of 
elongated nodules or hard argillaceous mummies, at the Sukkertop, on 
the West Coast of Greenland. 
In Case 35 are deposited some fine fragments (chiefly the heads) of 
fishes from the London clay of Sheppey. They belong to the genera 
Ccelocephalus, Brychcetus, &c., the true position of which is not yet 
determined. 
The few remains referable to the Eel family (Murs&noids) will be 
found in the lower shelves of Case 35. 
The specimens in Case 36 belong to the Order of Placoid fishes, 
consisting of spines of Aster acanthus, Oracanthus, which were too 
large to be arranged with the remains of allied genera in the small 
Table Cases, and which have already been noticed. 
The Wall Case at the north-east end (divisions 37 to 42 inclusive) 
are occupied by examples of Fossil Star-fishes of various kinds: these 
will be hereafter arranged in the new Room (adjoining Room III.) 
now in preparation. The principal objects in the Case are—the large 
group of Crinoid Star-fishes, or Pentacrinites (P. Hiemeri, Konig), 
from the lias of Boll, Wurtemberg; several specimens of the Briarean 
Pentacrinite, from the English lias ; a series of Crinoids from the 
Wenlock, or Dudley limestone ; “ stone-lilies ” (Bncrinus liluformis, 
Lam.) from the Muschelkalk of Germany; the Pear Encrinite ( 'Apio - 
crinus Parkinsoni), of the Bradford clay ; the Marsupite of the chalk ; 
Star-fishes ( Asteriadce ) and “ sand-stars” ( Ophiuridce), from the lias, 
oolites, and chalk; slabs containing Sea-Urchins (Hexnicidaris inter¬ 
media), with their spines attached, and slabs of carboniferous limestone, 
with remains of Crinoids and Echinidm. 
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 WsW 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. W. 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 JEolodori) from the lias at Monheim in Franconia, 
being the unique specimen described and figured by Soemmerring in
