Three new species of cestodes of snake and birds from Wuyi Mountains and Xiamen are described. The type specimens are deposited in the Department of Biology, Xiamen University. These new species are as follows.Ophiotaenia sinensis sp. nov. (Figs.1-2) Host. Natrix tigrina lateralis (Berthold). Location. Small intestine. Locality. Wuyi Mountains, Fujian Natural Reserve of Wuyi Mountains (27°40′N, 117°40′E). This new species is similar to O.grandis and O.japonensis but differs from them in the following characters: scolex is smaller; suckers (0.124×0.113) are also smaller than those of O.japonensis (0.15-0.28); testes (256-320) are more than those of O.grandis (200-250) and O.japonensis (90-130) with size \[(0.037-0.063)×(0.026-0.053)\] smaller than that of O.grandis \[(0.075-0.125)×(0.04-0.05)\]; cirrus pouch (0.513×0.147) is larger than that of O.japonensis \[(0.40-0.44)×(0.10-0.11)\], but smaller than O.grandis(0.64-0.75×0.24-0.26).Raillietina (Paroniella) lini sp. nov. (Figs.3-6) Host. Pycnonotus sinensis. Location. Small intestine. Locality. Xiamen (24°26′N, 118°04′E). This species is similar to R.(P.) pycnonoti and R.(P.) perreti but differs as follows: suckers armed while unarmed for R.(P.) pycnonoti and R.(P.) perreti which are from the same host of R.(P.) lini; Hooks (0.016-0.020) are longer than those of R.(P.) perreti and (174) are more than those of R.(P.) pycnonoti (105-115) but fewer than that of R.(P.) perreti (240); Testes (31-43) are more than those of R.(P.) pycnonoti (14-30) and R.(P.) perreti (22-29); cirrus pouch (0.112×0.054) is larger than that of R.(P.) pycnonoti (0.050×0.090). Anomotaenia amaurornisus sp. nov. (Figs.7-10) Host. Amaurornis phoenicurus. Location. Small intestine. Locality. Xiamen (24°26′N, 118°04′E). This species is similar to A.pyriformes and A.undulatoides but differs in the following characters: hooks (44-46) are more than those of A.pyriformes (28) with length (0.018, 0.025) shorter than that of A.pyriformes (0.051-0.053) and A.undulatoides (0.060-0.075); testes (25-40) are fewer than those of A.undulatoides (50); host Amaurornis phoenicurus is different from those of A.pyriformes (Gallinula crex and Crex crex) and A.undulatoides (Atticora fasciata).
