  abstract = {{F}eatures of the spermatozoon of #{C}alocarcinus africanus$ which are general for heterotremes and endorse its inclusion in the {H}eterotremata are : extension of the subacrosomal chamber almost to the anterior apex of the sperm, presence of an acrosome ray zone, and presence of a thickened ring where the capsule surrounds the base of the subacrosomal chamber. {A} feature shared with "higher" heterotremes is the restriction of cytoplasm to the periacrosomal region, the arms being nuclear only, in contrast with invasion of their chromatin with cytoplasm and microtubules in majids; and loss of a posterior median process, containing chromatin with cytoplasm and microtubules in majids; and loss of a posterior median process, containing chromatin, which is presend in majids as in raninids and homolids.
