granules on supraocular regions larger than those on interorbital 
or occipital areas; twelve upper labials, last one or two very 
small; ten lower labials; mental large, distinctly triangular, 
bordered behind by two large, elongate chin shields at least 
twice as long as wide; chin shields distinctly pointed in front 
and truncate behind, in contact with anterior lower labial for 
more than half their length and forming a mutual suture equal 
to nearly four-fifths their length; an enlarged scale separates 
the chin shields from second labial; two or three other en- 
‘larged scales bordering chin shields; granules on chin and throat 
. uniform in size; body above covered by minute granules inter- 
mixed with small, rounded tubercles arranged in sixteen irreg- 
ular rows; only a faint suggestion of a skin fold limits the 
abdominal region; forty-two rows of cycloid imbricating scales 
on abdomen; tubercles on upper surface of legs; two rows of 
tubercles continue on tail for about one-third of its length; tail 
with annulations distinctly marked on anterior part by straight, 
regular, transverse rows of scales; twelve or more irregular 
transverse rows to each annulation; tail below with widened 
scales of practically uniform length and width; scales in the 
swollen area behind anus distinctly enlarged; occipital region 
with an irregularly edged, depressed area; a slight prominence 
above auricular opening; digits widened with undivided trans- 
verse lamelle below, fifteen under fourth toe of each foot; 
adpressed hind leg reaches beyond elbow of adpressed foreleg; 
scales preceding vent slightly enlarged, growing somewhat 
smaller immediately in front of pore scales; a very long series of 
preanal and femoral pore scales meeting medially in a broad 
angle; femoral pore scales continue to near end of femur, each 
scale with a distinct circular depression; eighty scales, forty on 
each side; ear opening irregularly oval, its diameter about one- 
third of eye.
