- 1With the proper technique it can be shown that the sperms of the freshwater Ostracods are highly motile.
- 2The discovery of this motility has necessitated a re-orientation of the sperms. The sperms consist of a thin anterior part and a thicker posterior part, which is the flagellum.
- 3The nature of the movement is described.
- 4Apparently the sperms are now functionless.
