Extract

1. The shell gland of Fasciola hepatica produces an extremely hyaline secretion. The egg-shell is formed from the hyaline secretion.

2. As the eggs travel through the uterus, the shell is temporarily reinforced from the inside by vitelline granules. The vitelline granules are released when the vitelline cells enter the vitelline reservoir.

3. Views regarding the nomenclature of the shell gland are discussed.

4. The presence of an elliptical chamber in the shell gland is described. In this chamber, oocytes, vitelline granules and vitelline cells are mixed together, and here the secretion of the shell gland is released and the egg-shell is formed.

5. The arrangement of the cellular constituents within the egg is effected by the elliptical chamber.
