ABSTRACT
The translational and turning movements of the spore of Blastocladiella emersonii are described.
The turning movement appears to be a direct result of asymmetric flagellar activity.
The results indicate that co-ordination of propagated waves may not be exclusively effected by a system which involves the mechanical properties of the flagellum but also by stimuli derived from another source.

Holwill & Burge (1963) have shown that the velocity of an organism propelled by several flagella executing helical undulations becomes essentially constant when the number of flagella present exceeds ten. A similar conclusion is valid for organisms propelled by flagella executing planar waves.
