Among the specimens from Praslin were some overgrown hy a sponge ; the branches 

 thus hemmed in were ohyiously less hranched and more cylindrical than the free-growing 

 ones. The specimens from Terne Mahe are exactly like those from Mexico in Ktitzing's 

 herharium and figured in Tab. Phyc, Band xviii. tab. 27. The specimens from the 



■ 



other localities are like those gathered by Harvey at the Priendly Islands, No. 44, and 

 by Schmarda on the west coast of Ceylon. There is a difference between Harvey's and 

 Schmarda's specimens, but both being barren I abstained from further examination. 



4. Hypnea spec. 



Amirante, 25 fms. 



An indeterminable specimen, altered perhaps a little in consequence of the great 

 depth at which it grew.

The plants are all barren, but the whole outward appearance of these algae corresponds 



so well with the description given by Bornet that I feel no doubt that they belong to 

 this species.
