The chromatin becomes oriented into granular threads extending nearly the entire length of the somewhat elongated nucleus (Fig. 5, B). These threads contract and form rather definite chromosomes on the equatorial plate of the now fully formed spindle (Fig. 5, C). These chromosomes are again too small and too compact to enable one to count them. The beginning of the anaphase is again, as in C. curtus, a question of interpretation. I believe Fig. 5, D.
