Width of an upper eyelid contained in interorbital distance about 1-1/3times; horizontal diameter of eye about equal to distance between eyeand nostril, about 1-1/3 times diameter of tympanum; tympanum distinct,its distance from orbit equal to its diameter, overhung by a glandularfold running back from eye.
Choanae large; vomerine teeth in two elevated patches which lie between,and reach the posterior level, of choanae, the patches closer to eachother than to choanae; tongue rather small, subcircular, not or but veryindistinctly notched behind, not at all free behind; opening to vocalsacs behind level of tongue, the openings a short slit directedbackwards.
