SOME WONDEKS OF TEE SEA. 



CHAPTER III. 



JELLY FISHES VARIETY AND BEAUTY. 



A S a rule, the Jelly Fishes without pulsating discs are 

 *- not to be found on the shore. For them we must 

 go seawards and search for them in the waves. 



Not that we shall be likely to see them, for in most 

 of them the structure is too translucent to be distin- 

 guished from the water by any but the most practised 

 eyes, and if the surface of the sea be in the least dis- 

 turbed, they are absolutely invisible. Some, however, 

 float upon the surface, and show some part of their 

 structure above it. 



Such, for example, is the creature called Porpita, in 

 which the bell-shaped disc is modified into a flat, circular, 

 gristly plate, which acts as a float, to which are suspended 

 a vast number of tentacle-like appendages.
