244 SEPTEMBER 



some days more, some days less, extensive ; but for the 

 most part a considerable portion of the zoophyte was 

 hanging down from the shell. The Crab, on the other 

 hand, was evidently in clover, and showed no inclina- 

 tion to go back to his old lodging. 



On the 2d of May I found the Adamsia detached, 

 and lying helpless on the bottom of the tank, beneath 

 the Crab, who, when disturbed, walked off, leaving his 

 companion behind. I thought now it was a gone case, 

 and that it was all up with my elegant protegee. 



An hour or two afterwards, however, how great was 

 my surprise to see the Adamsia fairly established again, 

 adhering to the shell by a good broad base, and looking 

 more healthy than I had seen her for many a day ! 

 Strangely enough, she was adhering in a false position, 

 having taken hold on the outer lip of the shell, instead 

 of the inner, as usual. Here was a fresh proof of 

 intelligence somewhere ; and I at once set myself to 

 find where. 



Carefully taking up the shell with the aquarium- 

 tongs, and bringing it close to the surface, but not 

 out of water, I gently dislodged the Adamsia with 

 my fingers, and allowed it to fall prone upon the 

 bottom. I then released the shell with its tenant, and 

 drove the latter towards the spot where the zoophyte 

 lay.
