CAMPANULARIA FRAGILIS. 175 



minate in a single calyclc. Occasionally the branching is 

 carried further ; but in all the specimens which I have seen 

 it is simple and scanty. Below the calycle there are 

 several well-marked, somewhat compressed rings. The 

 stems are singularly tender and transparent. 



I am indebted to Prof. Wyville Thomson for the speci- 

 men from which this description is taken. Unfortunately 

 he was unable to study the reproduction, so that the species 

 can only be provisionally placed.

ZOOPHYTE very minute and delicate ; STEM flexuose, giving 

 off alternately, at each flexure, ringed and tapering pe- 

 dicels, which support the culycles, annulated above the 

 origin of each pedicel; HYDROTHEC.E much elongated and 

 very narrow, attenuated below, -with an even rim. Re- 

 production unknown. 



Height about \ inch. 



THIS species is smaller and more delicate even than the 

 C. neglecta (Alder), and it is as graceful in form as it is 

 fairy-like in size. The stem is decidedly flexuous, and 

 the calycles are remarkable for a combination of (com- 

 paratively) great length and narrowness. When the poly- 

 pite is extended, only the proboscis and the wreath of ten- 

 tacles are beyond the orifice. 



I suspect that the C. elongata of Van Bcnedcn is iden-
