room ix. Locust ( Scyllarus ), the Rock Lobsters ( Pa - 
linurus ), the Plated Lobster ( Galathea ), and 
the Crab Lobster, Porcellana, which, from the 
shortness of their tails, greatly resemble crabs 
in appearance; the Scorpion Lobster ( Thalas - 
sina), which lives great part of its life on land, 
and destroys the new made roads in India by 
the excavations it forms under them ; the 
Lobsters (. Astacus ), the specimen exhibited was 
pale red, nearly of its present colour when alive; 
Shrimps ( Palemon ), varying greatly in size. 
Then follows Case 8, the Sea Mantes ( Squilla ), 
the glass like Alima, and the Phyllosoma, with 
its shell scarcely thicker than a piece of paper. 
The rest of this Table is filled with the 
Crustacea which have sessile immoveable eyes, 
as, the fresh water shrimps, Gammarus , the 
Whale Lice ( Cyamus ), the Wood Lice {finis- 
cus ), Sea Bulls ( [Cymothoa ), and the King 
Crab, whose style at the end of the body serves 
the animal as a means of defence, and is used 
by the natives of America to form points to 
their arrows. 
Cases 9 and 10 (in the Windows), contain an 
arrangement of spiders ( Arachnida ). Amongst 
them are the Bird Spiders ( Mygale ), some of 
which form a tubular nest, closed by a moveable 
lid. One of those nests is shewn in this case : 
they are sometimes called Crab Spiders by the 
West Indians, and their bite is said to be dan¬ 
gerous.
