I. Introduction. 



The algge treated of in the following paper were collected by Mr. J. Stanley Gardiner 

 durinn- the Percy Sladen Trust Expedition to the Indian Ocean in 1905

The collection does not contain all the Phodophycege collected by Mr. Stanley Gard 

 the Lithothamnia have been worked out by the late lamented Mr. Foslie. 



The literature 



on the algre of this part of the Indian Ocean is scarce, for besides the paper by Mr. Eoslie 

 and the Peport on the Chlorophycese and Phseophyceae of the * Sealark' Expedition by 

 A. Gepp, M.A., P.L.S., and Mrs. E. Gepp, I only know of one paper in which more than 

 a few algje of this region are mentioned. Mr. Eeinbold, in " Meeresalgen der Deutschen 

 Tief see-Expedition," mentions 2Q species of Phodophycese from Diego Garcia and Mah^ 



10 of w^hich have been also collected by Mr. Stanley Gardin 



Besides this pap 



Mr. Eeinbold, I have found two other short references to algae from Diego Garcia and 

 the Seychelles. Mr. W. B. Hemsley adds a note on Algae to his " Peport on the 

 Vegetation of Diego Garcia." Of the algae named only Dasya indica, J. Ag., has any 

 interest for us at present; it is the only Ped alga mentioned. A note by "J. B." in 

 •Knowledge ' treats only of Myxophyceae, and may therefore be passed over in silence. 



The ' Sealark ' collection had special interest for me because I am just publishing, 

 with the aid of Mr. Eeinbold, the first part of a list of algae collected during the
