plant interesting by its structure and beauty, and so closely 
allied to the Spherozyge, which have already appeared. onor- 
mia seems to differ from Spherozyga chiefly in possessing a 
gelatinous branching matrix, so loose in structure that it can 
hardly be called a frond, surrounding the spirally-twisted fila- 
ment. This filament is of indefinite length, having many con- 
necting cells: the filaments of the Spherozyge, on the contrary, 
are generally short, with seldom more than one or two connecting 
cells. The fructification in both appears formed on the same 
type.
