Abstract

Magnacercous cercariae with heavily pigmented tails and possessing a pair of eyespots and seven pairs of penetration glands, some of which are para vesicular, were found to develop in the prosobranch gastropod, Cerithium coralium collected from a brackish water locality at Bheemunipatnam, A. P. India. The cercariae developed into metacercariae of Galactosomum ussuriense in the viscera of the fish Therapon jarbua. Successive stages in the development of metacercaria from the cercaria were followed. Natural infections with metacercariae were found in T. jarbua, Valamugil cunnesius and Megalops cyprinoides. The definitive host of G. ussuriense in the present area of investigation is still not known. This represents the second account of part of a life-cycle in the genus Galactosomum.
