So far as figure is concerned, this species has considerable resemblance to Pyxicephalus. Like 
Oxyglossus and Leiuperus, it is destitute of palatal teeth, but is easily distinguished from either of 
these by the form of its tongue and the non- visibility of its tympanum.

the last two-thirds free. Tympanum distinct. Opening of Eustachian tubes very small and oblong.

Figure slender. Head in front of eyes very short, the sides converging towards the nose ; the 
latter narrow and rounded. Eyebrows prominent ; eyes large and laterally protuberant. Tympanum 
small, subovate, directly over the angle of the mouth ; a series of minute warts above and behind angle 
of mouth. Anterior extremities rather long and very slender; toes free to the base, each, beneath, with 
several small tubercles. Posterior extremities slender, the toes delicate and without webs, a tubercle 
under each joint; apex of toes slightly swollen; the outermost and third toe of the same length, the
