Abstract

A research work was conducted during the period of March to December 2008 to observe the taxonomic<br> parameters of some selected common ranids of Bangladesh. . The specimens were collected from different areas<br> of the country. For the convenience of observation only four species of the family Ranidae, i.e., Euphyctis<br> cyanophlyctis, Fejervarya limnocharis, Hylarana typehensis and Hoplobatrachus tigerinus were studied. Tibiotarsus<br> articulation reached beyond the eye in F. limnocharis and H. tigerinus, in E. cyanophlyctis up to the eye and<br> in H. typehensis up to the nostril. The pupil was rounded in all but semicircle in H. typehensis; the tongue was pyriform in<br> E. cyanophlyctis and H. tigerinus but bifid at the tip in F. limnocharis and H. typehensis. Vomerine teeth were<br> present and hind limbs were overlapped in all species. All the measured taxonomic parameters were positively correlated<br> with snout to vent length.
