SPINOUS DEXAMINE. 
Body shining, the ninth, tenth, eleventh, and twelfth seg- 
ments produced into a spine; front produced and bent 
downwards between the antenne. 
The first joint of the upper antenne beneath towards 
their tips, have a little spine-like process. 
It is very common on the southern coasts of England, 
and is often taken by the shore-net, or beneath stones 
amongst the rocks at low tide. The legs are easily broken, 
which circumstance will account for Montagu’s having de- 
scribed and figured it without the monodactyle hands. 
Length three quarters of an inch.
