ANTHOZOA HELIANTHOIDA. 217 



lities in the west of Scotland, Mr. M'Andrew and Prof. E. 

 Forbes; off Cumbraes, D. L. 



This we have got several times from a fisherman w^ho 

 dredged it off Cumbraes. It was always on roundish stones 

 about the size of a man^s hand, and it wound itself in a 

 meandering manner round the stone, and as the surface was 

 not smooth, it took care to keep in the hollows. It is of a 

 reddish colour. When we first met with it, from its long, 

 small, worm -like appearance, we thought that it was an 

 annelide, till we observed the cells of the polypes, like little 

 warts, dotting it at regular intervals. The polypes are 

 whitish. The fleshy crust contains spicula.
