(both of Sciaenidae), respectively. The salient features of Zschokkella pseudosciaena sp.n. (Myxidiidae): trophozoite disporous; spore cylindro-ellipsoidal, suture elongated S-shaped, not ridged, 11.48 x 5.9 µm; a pair of equal, spherical and subterminal polar capsules, 3.58 µm in diam., 3 to 4 coils of polar filament in each capsule; coelozic. Myxoproteus cujaeus sp. n. (Sinuolineidae): trophozoite disporous; spore triangular or inversely pyramidal, 10.45 x 5.9 µm, suture moderately thick and bent at the middle; a pair of spherical and equal polar capsules towards the anterior surface, set wide apart, 3 to 4 coils of polar filament in each capsule, 3.27 µm in diameter.

Key words: Hooghly estuary, Myxidiidae, Myxoproteus cujaeus sp.n., Sciaenidae, Sinuolineidae, urinary system, Zschokkella pseudosciaena sp.n.
