Sphaerotheca dobsonii

Sphaerotheca dobsonii, the Mangalore bullfrog or Dobson's burrowing frog, is a burrowing frog found in southern India. It ranges from 2 to 3 inches from snout to vent (Wikipedia, general species account).

It is stout, with a large head and a short, rounded snout with an obtuse canthus rostralis. The space between the eyes is narrower than the upper eyelid, and the tympanum is very distinct, three-fourths of the diameter of the eye (Wikipedia, general species account).
