The distribution of Bothriocephalus sp., Guptaia sp., Mackiewiczia sp., Polyonchobothrium sp., Ptychobothrium sp., and Senga sp. in the alimentary tract of nine Indian hill-stream fishes are described. Though the region around pyloric sphincter was preferred by most cestodes, Senga sp. enabled its existence even in the latter part of intestine apparently because of its well developed adhesive apparatus on scolex.
