Authors


  • *For explanation of the Plates, see p. 48.

Summary.

  • 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.
