Abstract
1. By the smear method of preparation the doubly coiled spiral structure was ascertained in the metaphasic and telophasic Chromosomes in the heterotype division.
2. During the progress from the heterotype telophase to the interkinesis, the spirals of larger gyres or the major spirals were unravelled, and in the interkinesis only the spirals of small gyres or the minor spirals were observed.
3. In the homotype division, the Chromosomes were of the single coiled spiral structure throughout the division.
