Seven males and three females, identified as Trichostrongylus hamatus Daubney, 1933 were recovered from the abomasum of a steinbok shot at Deloraine Estates in the Kenya Highlands. No other Trichostrongylus species was present. The species was originally described by Daubney (1933) from Ovis aries also from the Kenya Highlands. The specimens from the steinbok were examined and compared with the original description of the species. Figs. 1–4 show drawings of the spicules and part of the bursa. Table I gives the measurements of Daubney's specimens compared with those of the present specimens.
