342 THE GLASSY ^QUOREA. 



dilate into a wide circular orifice, of which it formed 

 raerely a delicately-memhranous margin, the white 

 lines radiating through it (as seen at fig. 7) and pro- 

 longed into long narrow furhelowed filaments, remote 

 from each other, and connected by a sort of a web, 

 waved at its edge. Where the stomach can be T

 through the orifice without meeting any resistance 

 until it touched the clear, perfectly transparent sub- 

 stance of the umbrella, at the level of the highest 

 part of the sub -umbrella. 



Not a trace of colour appears in the whole animal, 

 which yet is exquisitely beautiful. It was swimming 

 near the surface, a mile or two ofi" shore, near Water-

 irritated in the dark. 



A day or two afterwards I obtained another speci-

 of the same size, one being frequently present not half 

 the size of the others. Fig. 6 shows a portion of the
