Seven specimens of the Japanese shrew mole, Urotrichus talpoides TEMMINCK, from central Japan were examined. A new nematode, Thominx urotrichi n. sp., was described from the mucosae of the mouth (tongue, palate and cheeks), the pharynx and an upper third of the esophagus. This nematode was characterized by long spicule and spicular sheath, and minute round depressions of the egg shell. Larvae of this nematode were observed in the skeletal muscle. Other parasites were also recognized : Larval nematode, probably Porrocaecum sp., from a lymph-node ; Capillaria sp. from the urinary bladder ; Hymenolepis sp. from the small intestine ; and Sarcocystis sp. from the skeletal muscle
