Twenty-nine Cryptotis parva were trapped at Lincoln Log Cabin State Park in Coles County Illinois between 22 December 1976 and 31 January 1978. Trapped specimens were necropsied and examined for the presence of helminth parasites. Nematode infections were found to be present in eight (27.2%) of the shrews collected with five (17.2%) of the males and three (10.3%) of the females infected. Three adult female nematodes were recovered from the small intestines of the host specimens, described and identified as the genus Capillaria. No male Capillaria were obtained and therefore species identification was impossible. However, the general appearance of the three female nematodes recovered, suggest that they may include two different species. Cestodes of the genus Hymenolepis were also recovered from nine shrews.
