THE NORTHERN ZOOLOGICAL GALLERY. 
FIRST ROOM. 
This room may be for the present considered as an appendage to the 
two foregoing. 
The Wall Cases. A series of the skulls of the larger Mamma¬ 
lia to illustrate the characters of the families and genera, and of the 
nests of birds, and the arbours of the two species of Bower Bird; the 
one ornamented with fresh-water shells and bones, and the other with 
feathers and land shells, &c. 
The Table Cases. The tubes of Annulose Animals, the casts 
of the interior cavities of Shells, and various specimens of shells, illus¬ 
trative of the diseases and malformation of those animals. 
Tables 1, 2 contains the shelly tube formed by the Serpulce, which 
have often been confounded with shells. The tubes of sand agglu¬ 
tinated together by the juices of the animal formed by the Amphitrites. 
Tables 3, 4 contain specimens of shells, exhibiting the different 
size of different specimens in their adult age, the changes of form which 
occur in the shell during the growth of the animal, the changes 
which take place in the cavity of shells, the manner in which shells 
are mended by the animal after any injury, and also how T the animal 
covers any excrescence which attaches itself to a shell, or removes any 
part which is in the way of its enlargement. 
Tables 5, 6 contain a series of plaster casts of the interior cavities 
of different shells of living moliusea, 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 called 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 I—7. The Lizards. 
The Cases I—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 ( Chamcesau - 
rus ), which have very long bodies, and small or very rudimentary legs. 
Case 5. The Seines and other allied genera, which are generally
