FISH GALLERY. 



The species of Amphiprion (662) are among the smallest. Some 

 of the Australian forms are of interest because of their habit of 

 associating with species of giant Sea-anemone (Discosoma) . On 

 pushing a stick into the mouth orifice of one of these Sea- 

 anemones there almost invariably dart out two or three of the 

 little fishes, which return into the interior of the anemone when 

 the disturbance is over.
