gonium. Indeed, were it not for the presence of older stages in the same 
group, one would without hesitation pronounce the youngest stages to 
be archegonia. In no case, however, were archegonia and antheridia 
found together in the older receptacles. 
Goebel figures a group of old antheridia, but gives no details of 
their development. 
The young antheridium (Fig. io) consists of a single basal cell and 
a hemispherical terminal one which gives rise to the body of the antheriw

dium. The first division wall in the terminal cell is vertical and may 
be nearly median in position, or it may divide the cell into quite unequal 
parts (Figs. 11, 12). In the former case the next divisions may follow the 
usual type of the Jungermanniales, i. e. in each half of the antheridium twb 
intersecting walls are formed, which also intersect the median wall, so that 
a cross-section of the young antheridium shows two triangular inner cells 
and four peripheral ones. A cross-section of a somewhat older antherr- 
dium of this type is shown in Text-fig. 3, D. This type, however, is 
much less common than that in which the primary wall is at one side
