Lamoroux's figure very incorrectly represents this species. The 

 cells are of the wrong shape, and too numerous. It may be de- 

 scribed thus : Coral, horny, flexible, branched, forked, sub- 

 quadrangular, not jointed, formed of four series of ovate convex 

 cells, with an oblong margined mouth, and scattered with flexible 

 root-like fibres.

Frond subcylindrical, cells white, beautifully frosted with small 

 pellucid dots ; the axis brown when dry. This coral forms 

 a peculiar genus, which may be thus defined : Coral subcylin- 

 drical, forked, jointed, rather crustaceous, pellucid, formed of four 

 or six series of ovate cells, with a subcylindrical subtubular 

 mouth, and having elongate bristle-like fibres. I can see no 

 difference between the New Zealand specimens and some from the 

 Cape of Good Hope, which I received from Dr. Kraus. It is also 

 said to be found in the European seas. 



Salicornaria differs from this genus, in being destitute of fibres, 

 and in the cells being six-sided, with a sunken mouth. 



Fam. CRISSIAD/E. 



145. Catenicella bicuspis. Gray. 

 Inhabits New Zealand. Dr. Sinclair. 



Coral white, pearly; cells half-ovate, truncated, with a small 

 compressed point on each side ; the mouth round. 



The coral branched, forked, circinate ; each joint formed of a 

 single cell, with the mouths all placed on one side ; the joint at 

 the divergence of the forks is formed of two united cells. 



146. Emma crystallina. Gray. 

 Inhabits New Zealand. 



The coral of this new genus is circinate, branched, forked, and 

 jointed ; the cells are all on one side of the coral, placed together in
