A research work was conducted during the period of March to December 2008 to observe the taxonomic parameters of some selected common ranids of Bangladesh. . The specimens were collected from different areas of the country. For the convenience of observation only four species of the family Ranidae, i.e., Euphyctis cyanophlyctis, Fejervarya limnocharis, Hylarana typehensis and Hoplobatrachus tigerinus were studied.

... , in E. cyanophlyctis up to the eye and in H. typehensis up to the nostril. The pupil was rounded in all but semicircle in H. typehensis; the tongue was pyriform in E. cyanophlyctis and H. tigerinus but bifid at the tip in F. limnocharis and H. typehensis. Vomerine teeth were present and hind limbs were overlapped in all species. All the measured taxonomic parameters were positively correlated with snout to vent length.
