Our fronds are hardly so regularly oppositely pinnated as the figures 

 in Phyc. Brit, one of the pairs being frequently wanting. 



There seems not the least risk of confounding this species with 

 Cliylocladia davellosa, its small size, and very much broader fronds and 

 divisions, will readily distinguish them. In our specimens, the lower 

 third of the primary frond is destitute of pinnee ; these being con- 

 fined to the upper two-thirds, giving the frond a somewhat flabellate 

 ap]3earance.
