THE CLOAK ANEMONE. 131 
membrane is so unusual that I do not remember to have 
ever seen it. 
Pagurus^ Prideauxii seems to be as dependent on the 
Adamsia, as the latter is on it. The only instance in 
which I have heard of its having been ever found disso- 
ciated from its friend, is the following, communicated to 
me by Mr. Kobertson : — 
“ Lately I dredged a small Pagurus Prid. unassociated 
■with Adanisia palliata. After a few days I put it into a 
jar with an Adamsia which I have had for some time. 
I saw them six hours after ; Pagurus had left his 
shell, and was perched on the top of Adamsia^ with his 
fore claws among the tentacles. Next morning Pagurus 
was dead, and Adamsia had quitted the hold of his 
shell.” 
This association, however, like so many other things 
that the natm-alist is constantly meeting with, is unac- 
countable. Why one species of Soldier-crab must needs 
seek the companionship of this Anemone, while other 
Soldier-crabs are able to live alone ; and why this species 
of Anemone must needs associate with the Soldier-crab, 
while other kinds of Anemone are solitary, I can by no 
means answer. Nor is the diflSculty in any wise solved 
by supposing — what we may easily grant — that each may 
find advantage from the other’s presence. Dr. Lands- 
borough pleasantly says, — “ In all likelihood, they in 
various ways aid each other. The Hermit has strong 
claws ; and while he is feasting on the prey he has caught, 
many spare crumbs may fall to the share of his gentle- 
looking companion. But, soft and gentle-looking though 
the Anemone be, she has a hundred hands ; and woe to 
the wandering wight who comes "within the reach of one 
of them, for all the other hands are instantly brought to 
its aid, and the Hermit may soon find that he is more
