SYNOPSIS. A new fresh water species of Actinosphaerium is described, the fourth member of the genus. Some of the more significant of its diagnostic traits are: 1) the Actinophrys‐like nuclei with peripheral nucleolar granules and without central rosette‐shaped nucleoli, 2) the occurrence of some nuclei in the ecto‐endoplasmic border and the insertion of axial filaments on them, and 3) the low ratio of endoplasm to ectoplasm.
