of different shells of living mollusca, to assist in determining the 
casts of fossil species often found in rocks. 
Tables 7, 8 contain a series of models on an enlarged scale, and 
some specimens of minute bodies, formerly ealled Nautili , but now 
formed into a group under the name of Foraminifera. 
SECOND ROOM. 
The Upright Cases round the room contain the collection of 
Reptiles and Batrachian Animals, preserved dry and in spirits, 
and the Table Cases the first part of the collection of the hard part of 
Radiated Animals, including the Sea Eggs, Sea Stars, and 
Encrinites. 
The Wall Cases. 
Cases 1 — 7- The Lizards. 
The Cases 1 — 3. The Monitors of Africa and India. In both 
countries they are venerated by the natives, who assert that they give 
notice of the approach of crocodiles, by hissing when they perceive one 
of those animals; hence their name. 
Case 3. At the bottom are the Heloderms from Mexico, which, unlike 
any other lizard, have a groove in the back of the teeth like serpents. 
They are said to be poisonous, but this may be a mistake, for ignorant 
persons are inclined to believe that all reptiles are dangerous. 
Case 4. At the upper part, the Safeguards of the tropical parts 
of America. They grow to a large size. The Crocodilurus has two 
keels in the tail like the crocodiles. The lower part of the Case, 
the lizards of Europe and North Africa, and the snake lizards ( Chamxz- 
saurus ), which have very long bodies, and small or very rudimentary 
legs. 
Case 5. The Seines and other allied genera, which are generally 
small and polished. They come from the warmer parts of both hemi- 
spheres. Some have distinct and strong legs, and others rudimentary 
ones ; as the blind worms, which have the bones of the legs hid under the 
skin ; they are all quite innocent. In the lower part of the Case are 
the Aprasia, Pygopi, Delmce and Fialisidce, or different kinds of blind 
worms from Australia, and the Acontia from the Cape of Good Hope. 
Case 6. The Geckos, or night lizards, which have the power of 
walking up glass, or even to run with facility back downwards on the 
ceiling of a room, like a fly. They come from the warm parts of both 
hemispheres, and differ greatly in the form of their toes ; some have the 
skin of the sides spread out to assist them when jumping from tree to 
tree. In the lower part are the various lizards allied to the Guanas. 
They are only found in America, and live on trees ; are very quarrelsome, 
and often fight with great ardour when they meet; they have the 
faculty of changing their colour with great quickness. The Anoles 
have the end of their toes dilated, which enables them to walk on 
smooth and perpendicular surfaces, like the Geckos. 
Case 7. The different genera allied to Agama. They are only 
found in the warmer parts of the Old World and Australia ; as the Mo- 
lochs, which are almost entirely covered with large spines ; the Dragons 
of India, which have the skin of their sides spread out into the form of 
wings, held up by the ends of the ribs ; when at rest these wings are folded
