Abstract
STUDIES on the spermatogenesis of Asellus aquaticus L.1 directed attention to the polyploid cells surrounding each testicular lobe. It has been found that these cells show cyclic variations of morphological characters both in nucleus and in cytoplasm which correspond to different phases of spermatocytic evolution. The latter is almost synchronous in each lobe, and a small bunch of spermatogonia remains in the basal portion of the lobe, to ensure the next spermatogenetic wave.
