Morphology

Vomerine teeth are in two small round groups between the choanae. The head is large, much broader than long. The snout is broadly rounded, with short canthi and very oblique, slightly concave lores. Nostrils are equidistant from the eye and the tip of the snout. Eye is large; interorbital space as broad as the upper eyelid. Tympanum is very distinct, oval, and slightly smaller than the eye. The first finger is longer than second, nearly as long as third. Subarticular tubercles of fingers and toes are feeble. A small, oval, inner metatarsal tubercle is present. The tibio-tarsal articulation reaches the eye. Skin is smooth and shiny; a glandular fold is present above the tympanum. Fingers and toes are free of webbing; tips are slightly swollen. Terminal phalange of all but the inner toe exhibit a sharp curved non-retractile bony claw, projecting through a slit on the lower surface of the extremity of the toe (Boulenger, 1900).

Dorsum is dark purplish brown, and venter is white. A black canthal and temporal streak are present, and a black transverse line is found between the eyes. Two dark bars are on the upper lip: the first under the nostril and the second below the anterior third of the eye. Limbs exhibit rather indistinct dark cross-bars. Lower surface of the crus and tarsus are dark brown (Boulenger, 1900).
