Forty-two Blarina brevicauda and 50 Sorex cinereus from various locations in Delaware County, Indiana, were examined for helminth parasites. From zero to eight parasites were found in 98 percent of the B. brevicauda. From zero to five parasites were found in 92 percent of the S. cinereus. Longistriata depressa, Porrocaecum americanum, P. encapsulatum, Capillaria blarinae, Protogynella sp., Hymenolepis anthocephalus, Panopistus pricei, Entosiphonus thompsoni, Brachylaima rhomboideus, Trichuris sp., Parastrongyloides winchesi, and a larval spirurid nematode, probably Physaloptera limbata, parasitized B. brevicauda. Larval nematodes, which may be Angiostrongylus michiganensis were abundant in the digestive and respiratory tracts. B. brevicauda also contained a minute, unidentifiable nematode from the small intestine. Tapeworms from four different B. brevicauda were in such poor condition as to make positive identification difficult. These were probably H. blarinae. H. parva; H. serrula; H. faculata; H, longi; two different unidentifiable hymenolepids; P. americanum; P. encapsulatum; A. michiganensis; Pseudophysaloptera formosana soricina; L. depressa; P, pricei; C. rauschi; P. winchesi; larval capillarid nematodes from the liver, probably C. hepatica; and three small unidentifiable nematodes parasitized S. cinereus.First reports include: P. winchesi in an American Sorex sp., Trichuris sp. from the intestine of B. brevicauda, P, pricei in S. cinereus, and larval capillarids, possibly C. hepatica, from the liver of S. cinereus.Possible relationships between the parasites' life cycles and the hosts' habitats were discussed.
