Larvae indistinguishable from those of the meningeal worm (Pneumostrongylus tenuis) were recovered from feces of white-tailed deer (Odocoile2ls virginianus) in Quebec (63 percent), Ontario (63 percent), Manitoba (49 percent), and eastern and central Saskatchewan (9 percent) in 1971. Adult worms were found as far west as 31 miles from the Manitoba-Saskatchewan border. The parasite is established in deer of the aspen parkland, and there is no apparent barrier to its continued spread westward. MENINGEAL WORM IN DEER * Bindernagel and Anderson 1349 MUNRO, S. A. 1969.

All of these records are from deer in the deciduous forest or coniferous forest biome or in the ecotone between these two biomes. In 1964, the meningeal worm was shown to be the causal agent of neurologic disease in moose ( Alces alces ), more commonly known as moose sickness or blind staggers (Anderson 1964). Since then, specimens of the meningeal worm have been recovered from the brain or spinal cord of moose with neurologic disease from the Fort Frances district of northwestern Ontario (Anderson 1965 ), Nova Scotia and New Brunswick (Smith et al. 1964, Smith and Archibald 1967), Maine (Behrend and Witter 1968), The nematode Pneumostrongylus tenuis, first described from white-tailed deer in New York State ( Dougherty 1945 ), has been reported in the United States from deer in Michigan ( Degiusti [DeGiusti] l9SS, 1963 ), Pennsylvania ( Alibasoglu et al. 1961, Samuel and Beaudoin 1966), western Virginia (Dudak et al. 1966), Minnesota ( Karns l967 ), Maine ( Behrend and Witter 1968), and Wisconsin (Samuel and Trainer 1969). It has also been reported from 12 states of the southeastern United States as far west as Arkansas and as far north as Maryland ( Prestwood and Smith 1969 ) . In Canada, it is known from the provinces of Ontario (Anderson 1963), Nova Scotia, and This content downloaded from 207.46.13.43 on Wed, 25 May 2016 05:34:58 UTC All use subject to http://about.jstor.org/terms 1350 Journal of Wildlife Management, Vol. 36, No. 4, October 1972 the parasite occurring west of southeastern Manitoba was a matter of speculation. The present study was undertaken to determine the distribution of the meningeal worm in Ganada west of New Brunswick. Our study was based primarily on the recovery of firststage larvae from deer pellet groups but was supported by the examination of heads from critical areas. This study was supported by funds from the Canadian National Sportsman's Show. We thank the personnel of the Quebec Wildlife Service, the Ministry of Natural Resources, the Manitoba Department of Mines, Resources and Environmental Management, and the Saskatchewan Department of Natural Resources for their assist-
