THE FURBELOWS. 369 



were perfectly regular, leisurely, and energetic ; yet 

 their effect in moving the body seemed feeble and 

 laborious ; every stroke, for example, raising the disk 

 an almost inappreciable distance, when it wished to 

 ascend from the bottom to the surface ; forming a 

 marked contrast to the minute but agile Turris 

 neglecta, which shoots at every contraction a distance 

 three or four times its own diameter. 



The Chrysaora does not rest at the surface as some 

 Medusae do ; but occasionally allows itself to sink 

 slowly to the bottom, where (or but slightly elevated 

 above it) it intermits for a while its laboured con- 

 tractions. 



The furbelows, as well as the tentacles, are organs 

 of prehension, used for the capture of prey. I have 

 some reason to believe that the former, at least near 

 their origin, perform an active part in digestion- 

 Casually touching the animal with a stick, not only 

 did several of the tentacles entwine round it, but the 

 furbelows also presently adhered to it, partially em- 

 bracing it ; and I became conscious that the latter 

 were drawing the stick towards the peduncle with
