Memoirs: Studies on the Germ-cell Cycle of Cryptocotyle lingua Creplin

1. Gametogenesis in the Adult

RAYMOND MILLARD CABLE 1

1 Fellow, Graduate College, New York University

1. The chromosomes of Cryptocotyle lingua have been counted and their shapes and sizes determined from observations on somatic and germinal cell divisions.

2. The differences in structure and staining reactions of the germinal cells in mature and immature worms are described.

3. Oogenesis and spermatogenesis have been followed from the primary germ-cells of the immature worm to the early cleavage stages.

4. More evidence has been added to that indicating the nonexistence of the ‘Primartypus’ of maturation postulated by Goldschmidt.

5. Gametogenesis in Cryptocotyle has been compared with that in other species.
