Plant creeping on the frond of another alga by means of small disc- 

 like roots emitted at intervals along the lower surface of a surculus. 

 The apex of the surculus is prolonged into a free portion, which is spar- 

 ingly branched, and everywhere distichously and alternately pinnated 

 with leaf-like pinnae from \ to nearly i mm. in length and a little 

 shorter in breadth. Pinnae broadly ovate or subrotund, or occasional- 

 ly oblong, slightly overlapping at the edges, rather obliquely inserted 

 on the branch, notched or blunt at apex by the dropping off of one or 

 two excurrent cells which are known to be prolonged into penicillate 

 filaments. They are traversed on the upper surface by a slender 

 midrib consisting of one row of cells, and are asymmetrical on both 

 sides of the midrib, and are transversely areolated with oblong 

 hexagonal cells. They are almost horizontally spread out arising 

 from the upper surface of frond and in the younger end of the bran- 

 ches, which is spirally inrolled on the dorsal side, the undeveloped 

 pinnae are erect facing to each other ; by this character the frond is
