Indian burrowing frog

Appearance

Its vomerine teeth form two oblique groups extending a little beyond the hind edge of the choanse. Its habit is stout. The head is short, with a rounded snout; the occiput is swollen, and the interorbital space is narrower than the upper eyelid. The tympanum is distinct, about two-thirds the diameter of the eye. The fingers are moderate and obtuse, with the first extending much beyond second, nearly as long as third; the toes are moderate, obtuse, and half-webbed; the subarticular tubercles are moderate, with the inner metatarsal tubercle being very large, sharp-edged, shovel-shaped, and longer than the inner toe; no outer tubercle or tarsal fold is present. The hind limbs are short, and the tibiotarsal articulation reaches the axilla or the tympanum. The skin above is smooth or granulate, with some scattered tubercles or short, interrupted longitudinal folds; a strong fold runs from the eye to the shoulder; the belly and lower surfaces of thighs are granulate. In color, it is light brown or olive above, with darker spots or marblings, often a light vertebral band, and sometimes another on the upper side of each flank; the throats of males are blackish, and those of females are usually brown-spotted. The male has two well-developed internal subgular vocal sacs.
