considerable length, those which spring from the lower 

 part of the stein often rising to the height of the main 

 shoot ; they are set closely together, and give off' plenti- 

 fully secondary branches and branch lets. The polypites 

 are of moderate size ; they are somewhat enlarged below, 

 and taper gradually towards the oral extremity. They 

 want the narrow neck that supports those of C. vayinata, 

 and there is no membranous cup at the base. The ten- 

 tacles are rather long and slender, and have very small 

 tips. The reproductive sacs, when mature, are very large ; 

 they often form a kind of collar round the lower part of 

 the body, but are sometimes more diffused. The dense 

 bushy growth of C. fruticosa is very unlike that of any 

 other British species.
