SAGARTIAD^. 
of tlie aquarium (quite close to tlie Sag. parasitica) ; and 
after a sliglit survey to see tliat all was right, he turned his 
left slioulder forward and ‘ backed in : ’ then he began to 
whisk his antenna3 and foot-jaws in a dreadful manner, and 
looked evidently quite content. I suppose this was a state 
of things the parasite perched on the rock above had long 
been waiting for ; for it was not long in moving its disk 
over the top of the small whelk ; and before the Crab knew 
where he was, tlie big Sagartia had pitched his tent on the 
roof of the Hermit’s house. Where the Hermit Crab goes, 
there goes the Sagartia; a quiet life it led before; a restless 
one it has to lead now. But doubtless it knows what’s 
best for it.” 
The crab who sustains the honourable office of porter to 
this species is invariably the brawny-limbed Paguriis hern- 
liardus, as P. Prideauxii is favoured with the support of 
Adamsia palUata. In the rude and blundering manner in 
which the bearer performs his office, it cannot be but that 
the poor Anemone sustains many a hard knock and many 
a rough squeeze among the rocks and stones over whicli 
his servant travels ; but he appears to bear these mis- 
chances with great philosophy : I know of no species which 
lives so constantly exposed. A rude shock will, indeed, 
cause it to withdraw its tentacles, and contract its disk into 
that button-like shape which is common to the tribe ; but 
this is only for a moment ; it instantly expands again, and 
remains full blown in spite of all its draggings hither and 
thither. Its skin is peculiarly tough and leathery ; a 
provision, doubtless, against the accidents to which its 
vagrant life exposes it. 
Mr. R. Q. Couch says that the favourite site for this 
Anemone (in the neighbourhood of Penzance?) is on the 
claw of the Corwich Crab {Maia squinado). Mr. Cocks, 
however, says tliat in the neighboiu'hood of Falmouth it is
