This very hirsute species frequently becomes covered with sponge, so that little of the shell is 
visible. Although long known as a Mediterranean Crab, its existence in our seas has only been 
recently discovered. The figure is taken from a large specimen, now in the British Museum, 
which was dredged off Penzance, and for some time lived captive in a tank.
