STEM tall, branched, annulated throughout ; branches 

 given off on all sides of the stem, bearing polypiferous 

 ramuli ; POLYPITES fusiform, prolonged beloiv into a 

 slender neck, winch is invested by a delicate membranous 

 cup-like extension of the polypary, ringed like the stem ; 

 tentacles 15-20, or more, rather long and slender, bent 

 inwards when at rest, extremities rose-coloured. 



GONOPHORES spherical, shortly stalked, produced in large 

 numbers over the greater part of the body. 



Height 3 or ^ inches in finely grown specimens. 



THIS is one of several species that have been confounded 

 under the name of C. ramosa. It is of tall and slender 

 habit, and somewhat irregularly branched. The polypary 

 is of firm texture and a decided horn-colour. The poly- 

 pites are slender and fusiform, tapering off towards the 

 mouth and downwards, and prolonged below into a narrow 

 neck of some length. The upper extremity of the body is 

 opake white, and the central portion of a reddish-brown 

 colour. The tentacles are commonly held curved inwards, 

 and have large, more or less deeply tinted roseate tips. The 

 portion of the polypary surrounding the slender base of 

 the polypite expands into a kind of cup, which extends 

 nearly to the lowest tentacles. It is composed of three or 

 four indistinct rings, and is simply membranous. 



The stem and branches are closely and regularly annu- 

 lated throughout. 



The capsules present no peculiarity ; they form a very
