1. luiDiEA spec 



Cargados Carajos, fragment with cystocarps, in alcohol, 22 fms. 

 Amirante, fragment with tetraspores, in alcohol, 20-25 fms. 



The specimens from both localities are too fragmentary to allow of a specific 



though the tetraspores being scattered among the peripheral cells 



determi 



indicate that the plant belongs to the subgenus Bhodoglossum, J. Ag. Both specime 

 are so alike in anatomical structure and outward appearance that, as far as can be 

 judged from the small fragments, I feel almost certain that they belong to the same 



species

1. POLTCCELIA YAN HCEYELLII, n. Sp. 



Amirante, 30-100 fms. ; in alcohol. 



Distribution. Malay Archipelago. 



The species is represented in the collection by such a poor and barren fragment that 

 I should have been unable to name it, had it not been for my studies on the rich 

 material collected during the VSiboga ' Expedition in the Malay Archipelago. This alga 

 will therefore be described and fisrured in the forthcoming paper on the 'Siboga' algse.
