摘　　要：An attempt has been made to systematically revise the Late Cretaceous （Turonian） bivalves of the Bagh Beds, central India. Altogether, fifteen species have been described here. The two species Nicaniella （N） trigonoides ＆ Protocardia （P） laticostata, which are earlier known from Late Cretaceous of Tiruchirapalli subbasin, southern India, have been recorded for the first time from Narmada Basin. The other species recorded are： Modiolus typicus, Neithea morrisi, Plicatula batnensis, P. numidica, P. instabilis, Lucina （L.） cf. fallax, Astarte similis, Opis corniformis, Protocardia hillana, P. madagascariense, Cytherea （Callista） lancianata, Trigonocallista spathi and Pholadomya sp.. During course of systematic revision, it has been found that many species described by earlier workers from the Late Cretaceous of Bagh Beds have been found conspecific to already known species from the Cretaceous of different parts of the globe and hence, they have been recorded here as junior synonyms. These species have immense implication in the palaeobiogeography of the region.
