Class 10. — Crustacea (ex. Crabs and Lobsters). 
The Foreign Crustacea occupy Wall-cases Nos. 12, 13, and 
14, and the British forms fill four-and-a-halt ot the ad]omm„ 
Table-eases, Nos. 80 to 83. Those British specimens too large 
for the Table-cases are arranged on the top shell ot the 'V a - 
cases. Attention is directed to Table-case No. 80, m which 
is exhibited a fine series of Trilobites from the We loch 
shale and limestone near Dudley. Many ot these Silui < . 
Crustaceans are remarkable for great beauty and '-anetj ot 
form, and exhibit in some instances (as m Phacops) the singular 
compound eyes, peculiar to the Arthropoda ; and m Encrmnrus, 
the eyes placed upon long eyestalks. , a 
The largest of the British Trilobites (Paradoxides) exceeds 
2 feet in length (see Wall-case No. 14 b) whilst the nearly- 
allied genus Pterygotus , from the Old Red Sandstone of 1 or ai- 
shire, measured fully 5 feet m length (see W all-case lo). 
Other specimens of this class are hxed on the W all adjomin^. 
Division B. — An arthropoda. 
Class 11. — Annelida (ex. Earth-worms, Sand-worms, lube- 
worms, &c.) 
Sea-worms (Table-case No. 79 and Wall-case No L>), being 
soft-bodied animals, are seldom preserved m a fossil state ; but 
their existence is proved by the tracks, burrows, and w orm- 
castings which they have left on the wet mud and upon the 
ripple-marked sands of the old sea-shores, before these had 
become hardened into shales and sandstones ; their microscopic 
teeth have also been found as fossils m the Lower Palaeozoic 
rocks.* Some species form shelly tubes, t and these are fre- 
quently found in rooks both of Palaeozoic and Secondary age.
