a canthal, a preorbital, a supraorbital, a postorbital, and a short orbitotympanic; the snout is short and blunt; the interorbital space is broader than the upper eyelid; the tympanum is very small, not half the diameter of eye, and generally indistinct (thus the common name). The first finger extends beyond the second; the toes are about half webbed, with single subarticular tubercles; two moderate metatarsal tubercles are present, with no tarsal fold. The tarsometatarsal articulation reaches the eye, or between the eye and the tip of the snout.
