OF THE MALDIVE AND LACCADIVE ISLANDS. 479 
in L. Laccadivarum each filament grows out independently from 
the thallus, and is markedly larger in every way than those of 
L. Harveyana. The basal cells of the filaments are swollen on 
one side and resemble the paraphyses of Splachnidium. From this 
portion of the filaments arise the short simple or forked branches 
which terminate in the plurilocular sporangia. Above the 
swollen cells comes the growing part of the filament, composed of 
short cylindrical cells with dense contents, and above these are 
the long hyaline cells which are pushed out indefinitely to form 
the Jong hair. 
I gratefully acknowledge Mr. Batters’s kind help in deter- 
mining the genus to which this species belongs.
