Description
The research work was conducted at the laboratory of the Department of Zoology, Jahangirnagar University during
the period of July to December 2008 with a view to know the taxonomic parameters of some selected
amphibians available in Bangladesh. The specimens were collected from different areas of the country. For
the convenience of observation only 4 species, Duttaphrynus melanostictus, Microhyla ornata, Uperodon
globulosus and Polypedates leucomystax were selected for the study. . Along with some observable criteria such as
color, size, longitudinal folds, etc. many recognizing taxonomic parameters as head length, head width, interorbital
diameter, diameter of tympanum, the distance between eye and tympanum, etc. were investigated in the
present study. Vomarine teeth were only present in P. leucomystax. Hind limbs were not overlapped in first
3 species whereas frequently overlapped in P. leucomystax. Tibio-tarsus articulation reached up to the
tympanum in D. melanostictus, up to the eye in M. ornata, does not reach the shoulder in U. globulosus, and
reached beyond the eye in P. leucomystax. All the taxonomic parameters measured were more or less positively correlated
with snout to vent length.
