Dunlins and western willets were collected on their winter feeding grounds at Bodega Bay and Bolinas Lagoon, California, during 1986. Six digeneans, eight cestodes, two acanthocephalans, and a new nematode were found in dunlins. Seven digeneans, two cestodes, one acanthocephalan, and the new nematode were found in western willets; four helminths including the new roundworm were common to dunlins. Thominx cecumitis sp. n. differs from other capillarid nematodes with a spinous spicule-sheath in having a short, globular vulvar appendage, peanut-shapcd eggs, a cuticular ball at the posterior tip of the body, narrow lateral alae, and a cuticular genital bursa.
