PE 
Protococcus consociatus nov. spec. 
Cells forming larger and smaller colonies. 
Protococcus verrucosus nov. spec. 
Ghlorococeum vitiosum nov. spec. 
Fig. 31—43, ordinary vegetative cells, of which fig. 
41 and 42 have somewhat crenulate membranes; 38 
has the membrane only partly erenulate. Fig. 44, 45, 
and 48 show sporangies, 46, 47, 49, 50, and 51, emptied 
sporangies or sporangies emptying themselves. 
Phaseolaria obliqua nov. gen. et spec. 
Fig. 52—66 show ordinary vegetative cells; fig. 52 
and 57 showing cells seen from above and from the 
side. Fig. 67—74, cells in zoospore-formation. Fig. 71 
and 73, cells with erenulate membranes. Fig. 75—77, 
emptied zoosporangia. Fig. 78 is a pile of cells of 
Phaseolaria obliqua. The contents are drawn in one 
cell only, forming zoospores. 
PI. II. 
Acanthococcus granulatus ReinscH var. aerophilus 
noV. Var. 
Fig. 84, 85, 82, 83, and 79, various advancing stages 
of reproduction. Fig. 81, 82 are emptied mother mem- 
branes. Fig. 87—89, very young specimens; the smal- 
lest ones measure only about 3,5 u in diameter. Fig. 
86, specimen with extraordinary low, rounded mem- 
brane-warts. 
Chlorella vulgaris BEYERINCK. 
Fig. 93, mother membrane with two aplanospores. 
Fig. 90 and 91, aplanospores escaping the mother 
membrane. Fig. 92, 94, and 95, cell-piles where the 
cells on account of the mutual compression are some- 
what flattened on one or more sides. The membranes 
are sometimes partly crenulate. Fig. 96—104, solitary
