CLADOPHORA MAGDALENA, n. sp. 
Gen. Cuar. Filaments green, attached, uniform, branched, composed of 
a single series of cells or articulations. rut, aggregated granules 
or zoospores, contained in the articulations, having, at some period, 
a proper ciliary motion. CLapopHora (Kéfz.),—from wdados, a branch, 
and ¢opew, to bear. 
CiapopHora Magdalene ; filaments capillary, blackish-green, short, decum- 
bent (?), matted together, slightly branched, irregularly bent ; branches 
patent or divaricate, curved, dichotomous or secund, with wide axils ; 
ramuli few, spreading, faleate, as thick as the cells from which they 
spring ; articulations thrice or four times as long as broad, filled with 
very dense opake endochrome; dissepiments very narrow, not con- 
tracted. 
Has. At Jersey, Miss Magdalene Turner. 
Descr. Filaments, in the only specimen examined, about an inch long, 
matted together, but not tufted, apparently growing either prostrate or 
entangled among the bases of other Algz, not much branched. Branches 
irregularly dichotomous, or angularly alternate, spreading with wide angles, 
often divaricate, curved, simple or once or twice divided; naked, or fur- 
nished with a few secund, falecate ramuli. Articulations thrice or four times 
as long as broad, those of the ramuli the shortest, filled with a very dense, 
dark green, minutely granulated endochrome (resembling that of C. rupes- 
tris); the dissepiments very narrow and scarcely at all contracted. The 
apices obtuse. Sudstance somewhat rigid, not adhering to paper in drying. 
Colour a dark, dingy-green. 
Not knowing to what described species to refer the apparently 
distinct little plant here figured, I give it a provisional name. 
Unlike as it is in ramification and general aspect to C. rupestris, 
the cells under the microscope strongly resemble those of that 
species; yet I can hardly think it next of kin to that  straight- 
growing plant, and perhaps C. fracta is more nearly related. 
Had it been more certainly characterized or more pleasing to 
the eye, I should have felt a greater pleasure in naming it from its 
discoverer, to whom this work is indebted for many interesting 
additions, and for a large proportion of whatever information it 
affords on the Algz of Jersey.
