 methods. In Abraxas grossulariata in the growing spermatocyte 

 the vacuoles are near the centrosomes, but not inside the Golgi 

 apparatus. During the spermatocyte division they are near the 

 chromosomes on the spindle and separate out into two sub-equal

groups. Throughout the formation of the acrosome the vacuoles 

 are near the Golgi apparatus (acroblast), but it is impossible to 

 say that they are in any way active. They moved down the 

 tail, but owing to the habits of the moth of transferring sperm in 

 bundles with much of the Golgi and vacuolar material attached he 

 could not state whether they were sloughed off. In Helix aspersa
