Spermatozoon of Arbacia showing sensilla amoeboidea. The regions of the spermatozoon already mentioned take the color. But for a short time there is a slight stain on the surface of the head also, before the middle piece is stained. After a variable time the head loses the color gradually and one can see a slow enlargement of the middle piece and the formation of delicate protoplasmic filaments therefrom, which move spo- radically. These deserve a more precise description. The basal part of the head has the appearance of a ring, somewhat thicker than the rest of the head. When the sperma-.
