STEM very slender and thread-like, pale horn-coloured, and 

 very transparent, irregularly branched; BRANCHES of 

 equal thickness with the main stems, ringed at their 

 origin; POLYPITES vase-shaped, yellowish brown, with 

 an opake- white proboscis and "between 20 and 30 long 

 slender tentacles ; GONOPHORES (male) clustered, borne 

 on short ramules, delicatelij annulated, springing from 

 the lower part of the stem or the creeping stolon, raised 

 on peduncles, and with a tubercle on the summit; 

 (female) somewhat oval, pedunculate, ranged round the 

 body of the polypite*. 



Height of zoophyte from ^ to | inch. 



THIS species is remarkable for its great delicacy and trans- 

 parency. The smooth and slender stems are just tinged 

 with the faintest horn-colour. 



The male sporosacs hang like clusters of fruit from the 

 extremity of very short branchlets, which occur only 011 

 the lower portions of the stem or on the stolon, the barren 

 polypites crowning the summit of the superior branches. 

 The gonophores are furnished with a tubercle at the top, 

 like those of E. arbuscula.

* There is very little variation in the gonophores amongst the species of 

 Eudcndrium. The males are usually clustered, the polypite that gives ori- 

 gin to them disappearing in great part as they advance to maturity. The 

 polypite that bears the female gonophores seems to be less subject to atropln . 

 which, however, probably sets in before the liberation of the ova.
