1. AYrangelia multifida, /. Ag. (Formerly GriffitJisia 

 muWjida.) 



Hab. On perpendicular sides of deep marine pools. Fre- 

 quent in the south of England and west' of Ireland. Eare 

 in Scotland. Caught (floating) by Mrs. R. M. Stark at 

 Saltcoats. Found by Major Martin at Ardrossan, and 

 dredged by him in Arran. 



Wlien this plant is seen in the water, it is remarkably 

 beautiful, both in colour and structure. Its fine rose-red 

 colour it soon loses in the open air or in fresh water ; but 

 the beauty of the structure still remains. The first speci- 

 men of it I ever saw, was given to me as a zoophyte. It is 

 rare in Scotland. Once or twice during the summer it may 

 be found by us, floating, but the specimens are always ex- 

 ceedingly fine, though not the fourth part of the size of 

 Irish specimens, some of which would cover a quarto page.
