Case 5. Arachnida; as Tarantulae, Scorpions, Pha- 
langia, and Acari, or Mites;—Myriapoda, as Scolopen- 
drae and Iuli. Also several mandibulated insects, such as 
Beetles, Dragon Flies, Wasps, and Ants; shewing their 
metamorphoses, or the changes they undergo in passing 
from the larva to the perfect state. Amongst them is the 
large American Prionus, and specimens of the White Ant 
( Termesfatalis , and bellicosus ), in different states, of which 
an interesting account is given by Mr. Smeathmann, in the 
seventy-first volume of the Philosophical Transactions. 
Case 6 . The Larvae, and Pupae of Haustellated in¬ 
sects, or those which in their perfect state live by suction ; 
as Butterflies, Moths, Flies, &c.; amongst which are 
several curious larvae of exotic Butterflies, variously armed 
with spines, &c.; and on the two lower shelves are a col¬ 
lection of Cirrhipedes, or the animals which inhabit the 
Acorn Shell and Barnacles, preserved in spirits. 
Case 7 contains the 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 the Mollusca in spirits, as the 
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, which 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 Hyalaea, 
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 lCf and 11 contain the continuation of the Gaste* 
ropodous Mollusca : 
Case 12. The animals of Bivalve Shells, shewing the 
various forms which obtain in the different genera. Those 
of the Pearl Oyster, from the Island of St. Christopher,
