CORYMORPHA. 125 



the Belgian zoophyte in Belfast Bay; but specimens of the 

 dried polypary from this locality, which he has kindly sent 

 me, are much stouter and of coarser texture than any ex- 

 amples I have seen of E. Dumortierii, and, I believe, must 

 be referred to some other species. A single stem with its 

 polypite, attached to a piece of drift-wood which I obtained 

 in the Isle of Man, cast ashore on the magnificent shingle- 

 beach at the Point of Ayr, is the only British specimen 

 that I know of. I have had the opportunity of comparing 

 it with specimens of E. Dumortierii supplied by Van Be- 

 nedeii, and have assured myself of their identity. 



The present form is of small size and great delicacy of 

 habit, and the stems are developed singly and not in clus- 

 ters. The polypary is of a light yellowish horn-colour and 

 transparent. It is slightly annulated towards the base of 

 the stem, which, in my specimen, tapers off very finely, and 

 is attached to a short creeping fibre ; indeed the tube gra- 

 dually expands upwards from the point of attachment to 

 the terminal aperture. Here and there in the course of 

 the stem there occurs a more or less perfect ring. 



The polypite is large for so diminutive and delicate a 

 species, and, like most of the tribe, is of a reddish colour.
