Autocolony

This may be because the formation of autocolonies within the mother cell wall is a considerable advance over the condition of free-lying spherical cells, and because along with the development of this autocolonial habit there has gone almost necessarily an axial differentiation of the individual cells.

This fact is of considerable interest as it shows how the autocolonies of certain of the Autosporaceæ may have arisen.

Autocolonies of 8 cells were occasional, and of 4 cells quite frequent.
