Extract

1. Eubothrium crassum (Bloch) is re-described with additional information about the scolex and genitalia.

2. Specific differences between E. crassum and E. salvelini are commented upon and figured.

3. The second portion of the uterine duct lying between the central chamber of Mehlis's gland and the uterine sac is established as the “fertilization chamber”.

4. Polar bodies and maturation divisions are described and figured in definite relationships with the ovum as evidence of normal maturation in a cestode.

5. The position of the receptaculum seminis is determined and a new name, the “vagina sac”, is given to what was previously described as a receptaculum seminis. It is thought to serve for propulsion of male and female cells into the uterine duct.
