tympanum very distinct, f to nearly once the diameter of the eye and 2 to 4 
times its distance from the latter. 
Fingers obtusely pointed, first and second equal and as long as or slightly 
longer than the fourth, third as long as or a little longer than the snout ; 
subarticular tubercles moderate or rather small, moderately prominent. 
Hind limb moderately long ; the tibia- tarsal articulation reaching the eye, 
the tip of the snout, or between these two points when the limb is stretched 
forward ; the heels meeting or narrowly separated, exceptionally slightly 
overlapping, when the limbs are folded at right angles to the body ; tibia 
twice in length from snout to vent, or slightly more or slightly less, shorter 
than the fore limb, as long as the foot or slightly longer or shorter. Toes 
obtusely pointed, entirely webbed, or at least f webbed, in which case one 
or two phalanges of fourth and one of third and fifth are free ; subarticular 
tubercles small and moderately or feebly prominent ; a more or less distinct 
fold along the inner side of the tarsus ; inner metatarsal tubercle elliptical, 
feebly prominent, | to | the length of the inner toe ; no outer tubercle. 
Upper parts with small tubercles and larger warts, some of which often 
form short, wavy longitudinal folds ; sometimes a longer glandular fold on 
each side of the anterior third of the back, extending to the posterior border 
of the upper eyelid ; a curved fold from the eye to the shoulder ; lower parts 
smooth, thighs granular near the vent. 
Brown, greyish-olive, or dark olive above, with dark brown or blackish 
spots which may form regular longitudinal series on the back and a cross- 
bar or a chevron between the eyes ; a pale green vertebral streak often 
present ; a more or less distinct dark canthal streak and dark and light 
marblings on the upper lip ; a more or less distinct light streak often 
extends from below the eye to the shoulder ; limbs with more or less 
regular dark cross-bars ; hinder side of thighs usually with dark marblings. 
Lower parts white, spotted, marbled, or vermiculated with blackish ; these 
markings may be restricted to the throat and breast. 
Male with internal vocal sacs ; the fore limb very strong ; a thick pad 
on the inner side of the first finger, covered during the breeding season 
with a greyish-brown, velvet-like horny layer, of which a similar but smaller 
patch is also present on the upper surface of the second finger ; small 
whitish, conical tubercles on the warts on the body. 
Tadpole similar to that of B. esculenta, but tail often longer, 2 to 2 J 
times the length of the 1)ody, and horny laljial teeth in more numerous 
series, viz. 5 or 6 upper and 4 lower, answering to the following formulae :
