would seem to be the product of a longitudinal divi- 
sion (figs. 12, 13, 15), but as such a division of chromato- 
phores has not hitherto, to my knowledge, been ascertained, 
Fig. 13. From a nemathecium from Kerteminde, November (Nawaschin). 
The end-cells are swollen and show very distinet chromatophores, partly 
paired. The nucleus is indistinet in the three first figures. The cell be- 
neath the monosporangium is short, deeply stained. 1015: 1. 
further proof must be demanded. On the other hand, the 
paired chromatophores might be supposed to be on the 
point of fusing together along the longitudinal axes, 
and this supposition is more in accordance with the cases

where the paired chromatophores are of different lengths. This 
interpretation is corroborated by the fact that the ripe spores 
seem to contain one single chromatophore. Paired chromato- 
phores were observed in end-cells which were still eylindrical 
and in more or less obovate, nearly ripe monosporangia. 
As mentioned above, the resting nucleus in the terminal
