Toes with a very narrow web and with small thin disks. Outer metatarsals united. 
‘Vomerine teeth; tongue free and emarginate behind. Pupil horizontal ; tympanum

Rather slender in general form. Snout broad, somewhat projecting beyond the 
mouth, with more or less obtuse canthus and sloping, concave sides; eye scarcely equal 
to its distance from the nostril. Tympanum round, with the vertical diameter but little 
longer than the longitudinal, half the area of the orbit (in females). Vomerine teeth 
in two prominent transverse series, well separated from each other, behind, but within, 
the level of the choane. Upper parts of the body and of the limbs smooth, sometimes 
with several flat tubercles; sides slightly tubercular; a glandular fold above the 
tympanum ; abdomen smooth, without folds or disk. Length of the body less than the
