Additional RADIATED ANIMALS and ANN ELIDES. By J. E. 

 GRAY, Esq. 



Fam. FLUSTRAD^. 



138. Membranipora pilosa. Johns, Brit. Zooph., t. 24, 

 f. 10, 12. 



Inhabits New Zealand, on Fuci. Dr. Sinclair. 



139. Menipea cirrata. Ellis, Zooph., t. 4, f. 1. 

 Inhabits New Zealand. Dr. Sinclair. 



Tricellaria of Fleming, and Crissia tricythara, Lamx. Pol. 

 flex., t. 3, f. 1, belongs to this genus, and Menipea hyalcea. 

 Lamx. Pol. flex, is a Catenicella. 



140. Acamarchis prismatica. 

 Inhabits New Zealand. Dr. Sinclair. 



Coral reddish brown, with prismatic reflections \ the cells two- 

 rowed, elongate ; ovarial cell globular, polished white. 



141. Selbia Zelandica. Gray. 

 Inhabits New Zealand. Dr. Sinclair. 



The coral of this new genus is frondose, forked, continuous ; 

 the cells are ovate, alternating, forming two rows on the upper 

 surface of the frond, and each furnished with a bristle-like fibre; 

 the other surface of the frond has a central ridge, and diverging 

 grooves. It much resembles Cabera and Canda of Lamoroux, 

 both genera very badly described and figured by that author ; 

 but it differs from the former in only having two instead of four or 

 six rows of cells, and from Canda in the fibres being free and 

 bristle-like, while in that genus the fibres are thick, and go from 

 branch to branch, forming the coral into a broad netted frond. 



142. Hal ophil a Johnston ce. Gray. 

 Inhabits New Zealand. Rev. W. Yate. 



Coral ridged, straight, horn coloured. This genus is peculiar 

 for being horny, and formed of t\vo alternate series of half-ovate 

 coriaceous cells, all placed on one side, and forming a continued 

 linear frond. It differs from Selbia in being destitute of any 

 root-like fibres, and in the cells being farther apart. It more 

 closely resembles Bicellaria, but it differs from that genus in not 

 being calcareous, circinate, nor jointed. Named in honour of Mrs. 

 Johnston.
