ABSTRACT Samples of rumen contents were obtained from 13 musk‐oxen living on Banks Island, N.W.T., Canada. Total protozoan numbers ranged from 38.5 to 124.6 times 10 4 per ml of rumen contents with a mean generic distribution of 52.4% Entodinium , 45.9% Diplodinium , and 1.7% Epidinium. A total of 18 protozoan species were found, six of which have not previously been observed in this host, i.e. D. (Diplodinium) costatum, D. (Ostracodinium) gracile, D. (Ostracodinium) trivesiculatum. D. (Eudiplodinium) medium, Epidinium quadricaudatum, and Epidinium parvicaudatum. Two new species of protozoa are described, Entodinium ovibos n. sp. and Diplodinium (Eudiplodinium) banksi n. sp.
