Present paper deals with the study of female reproductive organs and oogenesis in a new digenetic trematode "Allocreadium ophiocephali", Srivastava,1960. The helminth parasites were collected from the intestine of a fresh water fish Ophiocephalus punctatus of the family Allocreadiidae at the locality Dhirma nala, Rewa (M.P.). A few of the parasites were flattened on a clean slide under the slight pressure of a cover glass and fixed in alcoholic Bouin,s fluid for 12 hours. Stains like Gower's Carmine, Mayer's Paracarmine and Haemalum were used for the preparation of whole mounts for identification and the study of reproductive organs.
