and blushes when exposed to the light ; of this there is a very accurate 
wax model, to exhibit its appearance when alive. 
The Table Cases. The Sea Eggs, Star- Fish and Encrinites. 
Tables 1 — 9. Sea Eggs. 
Tables 1 — 6. The globular sea eggs. The club-spined echinus 
(Case 3), which has very large club-shaped spines; the tessellated 
echinus, which has short, broad, flat-topped spines like tessellated pave- 
ment. The spines easily fall off when the animal is dead, which makes 
specimens with spines on them rare in collections. 
Tables 7, 8. The Sea Pancakes, which are so depressed that there 
scarcely appears to be any room for their internal viscera ; some of them 
are lobed or fingered on the margin, and others pierced with slits. 
Table 9. The Galerites , which are most abundant in a fossil state ; 
and some of the Sea Hearts, the species of which are continued into 
and occupy Case 10. 
Tables 11 — 18. The Star- Fish. 
Some have five and others many rays ; some have the surface 
scattered with tubercles placed on the junction of a net-like skeleton, 
and others are formed of flat-topped pieces, like a tessellated pavement, 
each separate stem being fringed with an edge of minuter pieces; some 
of them bear on the top of each of the flat pieces a solid tubercle, 
which often falls off when the animal is dead. 
Tables 19—23. The Lizard-tailed Star-fish, 
So called because they often throw off the end of their rays when they 
are handled or put into fresh water, as lizards do when they are caught 
and cannot escape. 
Table 23. The Gorgon’s Head, 
The arms of which are repeated branches, so as to end in in- 
numerable flexible filaments, by which the animal attaches itself to 
marine bodies, and strains its food from the surrounding water. 
Table 24. The Comatula or Sea Wigs, 
Which are the recent representatives of encrinites, found so abundantly 
in certain rocks. 
THIRD ROOM. 
The Wall Cases round this Room contain the Handed and Glirine 
Mammalia, and the Table Cases the different kinds of Corals. 
The Wall Cases. Mammalia. 
Cases 1 — 28. The Handed Beasts. 
Cases 1 — 4. The Apes: as the chimpanzee of Tropical Africa; 
and the pongo or orang outan ; the siamang, and the long-armed 
apes or gibbons of Tropical Asia and the islands of the Asiatic Ocean. 
Cases 5— 7. The Capped Apes of Asia; as the Simpai, from 
Sumatra and Java ; the grey-headed capped ape, and the houlman of 
Continental India ; and the Nestor of Ceylon ; the houlman lives near 
the houses, and is venerated by the natives. 
Cases 8, 9. The Thumbless Monkeys of Tropical Africa ; as 
the guereza, which has a fringe of long white hairs on each side of
