THE COCOA-NUT EATER. 343 



We have nothing to do, however, with cases so 

 exceptional as the above : the occupants of our own 

 coasts are very similar to each other, both in their 

 structure and general ceconomy; and as the species 

 are few, the aquariist is not likely to be much embar- 

 rassed in his selection.
