PLATE 21.

P. H. GOSSE, _del._ LEIGHTON, BROS.

OLIVE SQUAT-LOBSTER. SHAGGY FLAT-CRAB. SCARLET SQUAT-LOBSTER.

]

A curious chapter in the history of this little creature, which I have

put on record elsewhere,[93] is, I think, so very instructive, that I

may venture to repeat some parts of it here. Let me premise that the

Crab habitually lives under stones, a habit for which the remarkable

flatness and thinness of all its parts adapts it; he has somewhat of

the appearance of having been crushed flat by the pressure of the stone

under which he lives. He does not wander much to seek his food, but

expects it to be brought to him, he making provision for its conveyance.
