Spermatozoa of plains mice were studied by transmission and scanning electron microscopy. The occurrence of a distinct dorsal hook and 2 ventral hooks joined at the base was confirmed. Acrosomal material covered the dorsal hook and appeared to constitute most of the 2 ventral hooks which contained nuclear material only at the base. Incubation in sodium dodecyl sulphate resulted in loss of all the material presumed to be acrosomal.
