Nirmal Kumar Sarkar Department of Zoology, Rishi Bankim Chandra College, Naihati, West Bengal, India Summary Two bivalvulid myxosporea Myxodavisia haldarae sp. n. and Ceratomyxa sardinellae sp. n. have been described from the gallbladder of Sardinella longiceps collected in the Bay of Bengal coast of West Bengal, India. The salient features of M. haldarae are: a large spore, backwardly directed shell valves end into sharp spine, spore-body 13.2 ± 1.42 (12-15) µm × 8.4 ± 0.74 (7.5-9) µm; polar capsule spherical 4.0 ± 0.71 (3-4.5) µm, and the characters of C. sardinellae – disporic sporogony, a small spore, broadly round ends of shell valves, suture distinct, 8.05 ± 1.095 (6.75-9) µm × 14.25 ± 1.061 (13.5-15.75) µm; polar capsule spherical 2.45 ± 0.35 (1.95-2.7) µm. These two species differ from the related species, which is demonstrated in the respective table.
