Contains some interesting Oligocene Corals (Turbinolia Case 104. 
and Caryophyllia), the freshwater Snail (Plan- 
orbis) of the Oligocene of the Isle of Wight ; also 
Sharks’ teeth (Notidanus, Odontaspis, and 
Carcharodon). The eggs of Turtles are rare fossils, 
and some exhibited here were found associated 
with a freshwater fauna. 
Here are some delicate fossil leaves from the Eocene of Cases 105, 
of Alum Bay in the Isle of Wight ; also discoidal 108 * 
Foraminifera known as Nummulites from Italy 
and India ; the giant Sea-urchin, Clypeaster ; a 
fine series of volute Gasteropods ; the extinct Cuttle- 
fish bone, Belosepia ; and a series of Sharks’ teeth. 
Cretaceous fossils are represented by a Fern stem Case 107. 
Tempskya, found in the Weald of Buckinghamshire ; 
Siliceous Sponges as Siphonia and Plocoscyphia ; 
“ Shepherd’s Crowns ” (Cyphosoma) ; Cephalopods, 
as Baculites (showing foliated sutures) ; and 
various Ammonites. Here are some good specimens 
of the teeth of a kind of Hay, Ptychodus, termed 
“ Fossil slugs ” by quarrymen. 
This Case is occupied by Jurassic Plants, chiefly from Case 108. 
the Wm. Bean collection, of Yorkshire. They 
comprise Liverworts (March antites) ; Horse-tails 
(Equisetites) ; Ferns (Todites, Cladophlebis, and 
Sphenopteris) ; the Fern-like (Taeniopteris) ; 
Fern-palms (Williamsonia) ; and Maiden-hair 
Trees (Ginkgo). 
Amongst Oolitic fossils here shown is a remarkable Case 109. 
Starfish (Astropecten). Other specimens of interest 
are “ pear Encrinites ” (Apiocrinus), in which 
the crown of this Sea-lily is shaped like the fruit ; 
a curious Bivalve with bar-like hinge-teeth, 
Parallelodon ; some ancestral Trigonias, differing 
from the living Australian species in having con- 
centric ribs ; and an interesting series of Ammonites, 
Belemnites, Prawns, and a Dragon-fly. 
Liassic fossils include fossil Ferns, as Laccopteris, Case 110. 
Dictyophyllum, and Sagenopteris ; whilst the 
Maiden-hair Tree has an early relative in Baiera. 
The beautiful little Brittle-star, Ophioderma, is seen
