In the present report, we present certain facets of the fine structure of the epididymal spermatozoa of an edentate, the nine-banded armadillo, Dasypus novemcinctus mexicanus. Although numerous investigators have devoted considerable attention to the morphology of spermatozoa using both transmission (Cleland & Rothschild, 1959; Bedford, 1965; Blom & Birch-Andersen, 1965; Nicander & Bane, 1966; Fawcett & Ito, 1965; Phillips, 1970; Pedersen, 1970; Phillips, 1972) and scanning (Koehler, 1970) electron microscopes, the armadillo represents a mammalian species in which the fine structure of the spermatozoa has not been investigated. While numerous features common to most mammalian spermatozoa have been observed in the armadillo, we report here some of the more distinctive features.

Sexually mature, male, nine-banded armadillos were examined during April and May. The animals were maintained for brief periods in the laboratory
