Phyllophora Brodizi and Actinococcus subcutaneus. 23 
chogynes and no other signs of a fertilization were ob- 
served. The case represented in fig. 11 D might suggest a 
transferring of a nucleus from the carpogonium to the 
auxiliary cell, but the narrow downward growing septate 
filament which has not the appearance of containing a 
fertile nucleus, and the long distance between the sup- 
posed carpogonium and the bearing cell do not favour this 
interpretation. Moreover, I do not feel convinced that the 
carpogonium-like body is really a carpogonium; it might 
perhaps be some endophytic Rhodophycea. 
IV. The Origin of the Nemathecia-producing Filaments. 
It happens that procarps consist of more than four cells. 
As shown in fig. 8 A, carpogonial branches may bear a 
two-celled branch on their lower-most cell, and procarps 
without distinct carpogonium may sometimes consist of a 
greater number of irregularly arranged cells (fig. 10 E, F). 
I was for some time inclined to believe that such groups of 
cells might be able to give rise to the nemathecia-produc- 
ing filaments; but I found no facts to support this sup- 
position. After searching for a long time I finally suc- 
ceeded in finding the origin of the filaments referred to by 
following the fate of the bearing cell that should normally 
become an auxiliary cell. This cell is originally uninucleate 
as shown in fig. 8B to the left, but the nucleus is not 
visible in most of the figures, in some cases it is hidden 
by the granular matter (fig. 10 B). Later a greater number 
of small nuclei appear, much as in the analogous cell in 
Phyll. membranifolia (fig. 2). In the case pictured in fig. 
10D the auxiliary cell shows some 20 nuclei and these 
must all have arisen by division of the original single
