Silvestri. Silvestri claims that this " nucleolo" is a 

 plasmosome which was cast out of the oocyte nucleus 

 at an early stage in the growth period, but an exami- 

 nation of my material proves that it really contains 

 all of the chromatin of the oocyte nucleus. Since it is

not a nucleolus, at least in the species I have studied,

 the term ' keimbahn-chromatin ' will be applied to 

 it.

 through an oocyte (o) in an early stage of growth. It 

 is surrounded by follicle cells (fe) and accompanied by
