South Court. 
In the center of this court are four groups of White-tailed 
or Virginia Deer, representing the animals in the four seasons. 
The case at the north end contains a group of Mountain Sheep, 
and that at the south end contains a group of Polar Bears. 
Under the North Gallery and along the sides of this court 
are arranged table cases, numbers one to thirty-four containing 
Shells. 
MOLLUSKS. 
The collection of Shells or Mollusks contains 7,000 species or 
more. It is believed to represent fairly well the subject of 
Conchology. The collection is shown in 34 table cases, in the 
South Court. In the arrangement of the families Dr. Paul 
Fischer’s classification in its reverse order has been followed. 
Cases 1 and 2. — These cases contain a small collection of 
Brachiopods; these are not Mollusks, though in external form 
they resemble the Lamellibranchs. The Brachiopods were very 
numerous in earlier geological times. The Mollusks proper 
follow the Brachiopods in Case 1, the important families repre- 
sented are the Anatinidce, Pandoridcs, Tellinidce and the Tere- 
dinidcB (Ship Worms, Piddocks, etc.) ; examples of injury done 
submerged wood by the Ship Worms; Pholadidce (Burrowing 
Shells) ; Myidce (Soft-shelled Clams). 
Case 3. — SolenidcB (Razor Shells) ; PsammohiidcB ; Dona- 
cidce (Wedge Shells). 
Case 4. — Veneridce, a very large family which contains many 
beautiful shells; ChamidcB. 
Case 5. — Cardiidce (Cockle Shells) ; Tridacnidcs (Giant 
Clams) ; two very large examples of this family can be seen in 
a separate case; UnionidcB (River Mussels). 
Case 6. — Unionidce continued, and a series of shells illustrat- 
ing the various stages in the making of Pearl Buttons. 
Case 7. — Unionidce continued. 
Case 8. — UnionidcB continued. 
Case 9.— In this case is represented a collection of Pearl- 
bearing Shells from Wisconsin, also a number of pearls. It con- 
tains also representatives of the Arcidce (Ark Shells). 
Case 10. — Mytilidce (Mussels) ; AviculidcB (Wing Shells), this
