 out spines) : Hincks, Ann. N. H. ser. 2, viii. 360 (the 

 same). 



Polypides borne on a flexuons, transparent stolon, more or 

 less branched ; often densely clustered. Body whitish, 

 cup-shaped, somewhat compressed laterally, usually \e\j 

 ventricose on one side (the dorsal or anal), and sub- 

 truncate on the opposite ; tentacles 14-24. Peduncle 

 stout, tapering slightly towards the top, and covered 

 with short obtuse spines. 



Var. a {glabra) . With the peduncle smooth. 



* It must be held doubtful whether Bosc's species is identical with the 

 present. His figure is of no value ; he makes no mention of spines on the 

 stem, and describes the whole zoarium as being of a sulphur colour. His 

 specimens were attached to Fucus nutans.
