Unlike the adult spermatozoa described by Paulmier ('99) and Stevens ('05), the author's preparations show a distinct region of cytoplasm around the chromatic rod, and fail to demonstrate that the sheath is entirely, or even mostly "used as food material for the growth of the tail sheath," as Paulmier described it (p. 254; also Figs. 56 and 57). The author's haematoxylin preparations show no acrosome or.
