SUMMARY
The proposal presented indicates that anaphasic chromosomal movement in the scorpion, C vittatus, is associated with enlargement of vesicles some of which apparently are connected to or closely associated with the chromosomal microtubules. Filling of vesicles attached to the centriole end of the tubules could greatly enhance the pulling of the chromosomes toward the centriole region. It is suggested that this mechanism could work in combination with other known phenomena associated with cell division.
