Balaenopterid whale specimens preserved in several institutions totaling 19 were examined. Specimens identified to species level were 14, i.e. 3 Balaenoptera musculus, 6 B. edeni, and 5 B. omurai. The remaining 5 specimens were not identified. The existence of B. omurai from Myanmar waters was confirmed based on the morphological characters of the skull and the first rib. This article is the first confirmation of this species in Myanmar. Among the two already “confirmed” species, B. musculus was identified by Smith et al. (1997) based on the actual specimen in the Natural History Museum, however for B. edeni, the specimens we examined were not observed for species identification and no preceding work reported the existence of B. edeni, except for the type specimen collected in Mon state in 1871 and now preserved in the Indian Museum, Kolkata (Anderson, 1879).
