THE CYCLOUM AND SYRINX. 157 



THE WARTY CYCLOUM. 



I found at low water near the Tunnel what seems a 

 curious variety of Cycloum papillosum. It embraces 

 the slender stem of a red sea-weed, encrusting it all 

 round, so as to form a cylindrical or sub -spindle- 

 shaped mass, not at all lobed, an inch in length, and 

 J inch in diameter. A portion of the membranous 

 frond accidently hanging down, has been attached by 

 the surface of the polypidom, and adheres firmly. 

 The substance is fleshy, closely covered with conical 

 papillae, which appear imperforate (under 200 lin.), 

 and certainly do not contain the polypes ; they are 

 more or less filled with green granules and vermicular 

 threads, which give a colour to the whole mass, of 

 olive brown. The polypes protrude seventeen long 

 tentacles (I counted four or five specimens over and 

 over, and invariablv found this the number) set with 

 cilia, and expanding in the form of a bell. 



Harvey's syrinx. 



On turning over a flat stone at the water's edge at 

 Wildersmouth I picked up a curious creature, not 

 very attractive indeed to look at, but which I found, 

 on examining Prof. Forbes' Brit. Starfishes at home, 

 to be a rare species. Syrinx Harveii. His figure is 

 admirably exact, and agrees with mine in size and 

 contour. My specimen is lively for so dull a creature, 

 inverting and unfolding its proboscis with great 

 rapidity, and to a length fully equal to that of its 

 whole body besides. The very extremity is encircled
