mens which I obtained on the beach at Bangor, co, Down in 1833; 

 and subsequently dredged in the loughs of Sfcrangford and Belfast, 

 are regarded by me as identical in species with the large greyish- 

 white and rugose forms procured on the open coast of Down at 

 Ballywalter. Examples precisely similar to the latter, are on Algfe 

 in my collection from Van Diemen's Land." W. Thompson.

Hab. Common on all parts of the coast, adherent to flexible 

 zoophytes, the Sertularinre of deep water especially ; to old shells, 

 and oftenest within old bivalves ; and to algse. " Ex mari Cornu- 

 biam alluente allatie Sertulariai eandem crebram, in piso majores 

 glomeres convolutam aut laciniosos passim et revolutos flosculos 

 mentientem exhibuerunt," Pallas. 



Polypidom adherent by a narrow base, calcareous, of a faint pur- 

 ple colour or white, depressed, irregularly divided, the segments flat, 

 bifid, spreading, more or less revolute, obtuse, the under surface even 

 and striate, the upper rough with the tubulous cells arranged pret- 

 tily in transverse rows, but divided by a central groove, which winds 

 along the branches : the cells are generally placed in close apposi- 

 tion, sometimes they are disjunct, and the walls are minutely frosted.
