title: On a triple infection of strigeid metacercariae in an Indian fresh-water fish, Xenentodon cancilla.
abstract: Three new species of strigeid metacercariae viz., Neascus hoffmani n. sp., Neascus nanaksagarensis n. sp. and Tetracotyle aglandulata n. sp. are described here from a fresh-water fish, Xenentodon cancilla (Ham.); of these, the former two resemble N. xenentodoni PANDEY, 1970 as well as N. hepatica CHAKRABARTI, 1970 while the latter one T. xenentodoni CHAKRABARTI, 1969. - N. hoffmani and N. nanaksagarensis are pharyngeate forms and each has its own pattern of reserve excretory system. N. hoffmani has a spinose body, while N. nanaksagarensis has an aspinose body. - Tetracotyle aglandulata has a lobed hold-fast organ, but lacks a hold-fast gland. Further, in this form fore-body and hind-body is not marked and it has its own characteristic reserve excretory system.
