disks ; subarticular tubercles moderately prominent; a single meta- 
tarsal tubercle. Hind limb short. Back with more or less distinct, 
irregular, longitudinal warts ; a fold from the eye to the shoulder ; 
lower surfaces smooth, except the hinder part of the belly and the 
thighs, which are granulate ; a circular flat gland below each thigh 
on its inner side; this gland perforated in the male. Dark grey 
above, with or without darker markings, the most constant being a 
cross band between the eyes and cross bands across the hind limbs ; 
sometimes a light vertebral line ; lower surfaces dirty white, closely 
marbled and dotted with black; lower lip tessellated with black and 
white.

Vomerine teeth in two small, rather widely separate groups 
behind the level of the choane. Head moderate; snout subtri- 
angular, truncate; canthus rostralis angular; loreal region nearly 
vertical, distinctly concave ; interorbital space as broad as the upper 
eyelid; tympanum distinct, two thirds or three fourths the dia- 
meter of the eye. Fingers moderate, first not extending as far as 
second ; toes moderate, three-fourths webbed ; tips of fingers and 
toes dilated into small, regular disks ; subarticular tubercles small ; 
a small inner metatarsal tubercle. If the hind limb is carried for- 
wards along the body, the tibio-tarsal articulation reaches to between 
the eye and the tip of the snout. Back with more or less distinct, 
flat smooth warts; a fold above the tympanum; lower surfaces 
smooth, except the hinder part of the belly and the thighs which 
are granulate; a circular flat gland with a more or less distinct 
median depression below each thigh on its inner side. Dark,brown 
or blackish above ; a black temporal spot; loins marbled with black 
and bright yellow; axille sometimes yellow; hind limbs with 
rather indistinct darker cross bars; hinder side of thighs black, 
generally dotted or marbled with yellow; lower surfaces brown,

Vomerine teeth in two small oblique groups behind the level of 
the choane. Head moderate; snout subtriangular, rather promi- 
nent; canthus rostralis distinct ; loreal region nearly vertical ; inter- 
orbital space as broad as the upper eyelid; tympanum distinct, 
half the diameter of the eye. Fingers moderate, first shorter than 
second ; toes rather short, entirely webbed; tips of fingers dilated 
into large disks, the diameter of which equals one third that of the 
eye; tips of toes dilated into smaller, but well-developed disks ;
