In the large Mytilns acrosome, three differentiated regions can be dis- tinguished, consisting of a basal structure which seems to be concerned with the extrusion of the filament; a distal region containing what is believed to be an egg- membrane lysin; and an axial structure which appears to be a tubular sheath, possibly surrounding a precursor of the filament. The same regions can be seen in the spermatozoa of Pctricola, Spondylus and Mactra. In the smaller acrosomes of Lithophaga.
