Termites; the larvae of Coleopterous and Hymenopterous 
insects, as Cerambyces, Wasps, and Tree Ants. The nests 
of different species of Wasps and Bees, with that of the 
Bird Spider, with its curious moveable lid. 
Case 7 contains Mammalia in spirits, as Bats, Shrew 
Mice, Opossums, and some very young specimens of larger 
animals. 
Case 8 contains a series of Annelides, including Sea 
Worms, Lob Worms, Leeches, Planariae, and other kinds of 
Worms, in spirits. 
Cases 9—12 contain Mollusca in spirits, as various 
kinds of Cephalopodous Mollusca, the Cuttle Fish, 
or Sepia, the animal which affords the pigment so called; 
Octopus, and other genera of the order, as Cranchia, and the 
Ocythoe; the latter is often found in the Paper Nautilus, and 
thought by some to be its original inhabitant. Here also 
are the Pteropodous Mollusca, or those whose wing-shaped 
feet are on the side of their head, as the genera Hyalsea, 
Cleodora, Clio, Cymbulia, and Limacina. Likewise 
Heteropodous Mollusca, as the animals of the Cari- 
naria, and Pterotrachea; and some of the Gasteropo- 
dous Mollusca, which walk on a flat expanded disk, in¬ 
cluding the Slugs, and the animals which inhabit spiral 
shells. 
Cases 10 and 11 contain the continuation of the Gaste« 
ropodous Mollusca. 
Case 12. The animals of Bivalve Sheiks, shewing the 
various forms which obtain in the different genera. Those 
of the Pearl Oyster, from the Island of St. Christopher, 
with some large pearls imbedded in their bodies, deserve 
particular attention. On the lower shelves are the tuni- 
cated animals, as the genera Biphora, Ascidia, &c. 
In Case 13 are Radiated animals preserved in spirits, 
as Sea Wigs ( Comatula ), Sea Stars, or Star Fish ( Aste - 
rias ), and Medusa’s Head, ( Alecto ), with their finely 
divided arms, with which they filter the water, to separate 
the small mollusca on which they feed. The Lizard-tailed 
Star Fish ( Ophiura ), which attach themselves to coral 
by their flexible arms ; the Sea Eggs {Echinus), and 
Sea Hearts ( Spatangus ), the Sea Lemons, Sea Cucum¬ 
bers ( Holothuria ), some of which are much sought after
