FIG. i. — A polymorphous spermatogonium in the " perfect resting ; The form of the nucleus allows the most perfect metabolism. Numerous chromioles are connected by a thread of chromoplasma. A network of linosomes is partially indicated, the individual granules being connected by Linopodia. A large chromoplast with endochromatic granules. Eight (hromatic grannies. A single archosome in the cytoplasm, the latter only partially indicated by small open circles. A single large linoplast, with seven endonucleolar granules. structures arc in any way intimately connected with the archo- some. The three spheres mentioned above surround each other, like three concentric shells, at the time when the cell is in par- tial resting stage ; but at a later stage, or as soon as the prophase is entered, these spheres break up and scatter in the cytoplasm proper. Each one of the spheres constitutes an independent structure, and they are not developed one from the other. 1 7W. Cal. Acad. Sfi., 30! Ser., Zool.
