BRITISH ZOOPHYTES. 801 



Hab. : Zetland Seas {Forbes), Hebrides (A. 31. K), 

 Coll Island (D. L.), North Sea {A. 8. P.). 



The zoaria are erect, white, and dichotomously 

 branched, growing to the height of about ^ inch. The 

 branches taper at each end. The cells are tubular, 1 — 4> 

 or 5 in each series, and are bent outwards from about 

 the centre of each cell at right angles to the medial 

 line of the zoarium.

 • This is the " Small Purple Eschara '' of Ellis (Cor. 

 74). It grows to a length of about ^ an inch or a 

 little more. It is branched dichotomously, and is of a 

 purple colour. The zooecia are in rows, close to each 

 other, the series being semi-alternate. The cells are 

 generally free towards the extremities. They are 

 minutely frosted and punctured. This is a very at- 

 tractive species, and has been described and figured 

 by most zoophytologists. 



Genus IV. Entalophora, Lamoiiroux. 



Zoarium erect and ramose, rising from a more or 

 less expanded base, composed of decumbent tubes ; 

 branches cylindrical. Zooecia tubulai', opening on all 

 sides of the branches. — T. H.
