The ruminant arterial worm Elaeophora schneideri is reported for the first time from the moose, Alces alces, in Montana. One of four infected animals examined during 1971 was blind and had extensive intimal proliferation in the leptomeningeal arteries, areas of cerebrocortical neuronal necrosis, and numerous hemorrhages in the brain. Similarities were noted in the lesions of elaeophorosis in moose and wapiti.
