Description. — General form depressed; head not so short as in P. theobaldi, F. oljv'ier %, 
&c., and tail longer. In adults the fore limb falls short of the thigh, or barely reaches it , ® 
hind limh extends to the eye ; the tail is one- third to one-half longer than the body with j 
head. The base of the tail is depressed and slightly dilated, thence the tail tapers gradua^y^ 
it can be coiled upwards near the end. Toes rather long ; the fourth toe on the hint 
exceeds the third by more than the length of the claw, and has both sides fringed ; the 011 
edge of the third toe is also fringed ; the fifth toe of the hind foot without the claw falls s io^ 
of the point of union of the third and fourth toes. Claws yellowish, strong ; the clan o ^ 
fifth toe on the hind foot longer than the rest. Nine to ten triangular teeth on each side m 
jaws; six pointed anterior teeth in the upper jaw, four in the lower; the outer pan’ in ‘ . g 
jaw elongate. The largest specimen measures 6' 25 inches, of which the tail from the anu- 
3*75, head 0*75, fore limb to the end of the toes 1*4, hind limb 2*2. ^ 
Scales of the head above convex, tubercular, not varying much in size, as a rule, ^ ^ 
nostril in a larger scale, sometimes divided horizontally. Scales of the superciliary 1 ^ 
larger ; each eyelid with a fringe of about nine rather larger scales, the lower row l )0ll ^ a j 
Upper labials twenty-seven to thirty-one, with convex margins ; rostral scarcely larger. 
or lower rostral generally much larger than the lower labials, which are, as a rule, rather ‘ 
in number than the upper labials. Scales near the lower labials rather larger than the m 
ing scales of the throat. Scales of the body about the same size above and below ; all 
hack and belly are smooth, rhomboidal, and arranged in transverse rows, those on the 
subimbricate; on the sides they are smaller and more granular, especially belu 111 
shoulder, where the red patch consists of small granular scales. I count from 9° t g^ a j cS 
scales round the middle of the body in adults, rather fewer in young specimens. ^ 
on the limbs usually rather bluntly keeled above, smooth below ; those beneath 11 ^ 
sharply keeled, cross-plates beneath the toes with several keels. The pointed 
a fringe on the outer side of the fourth toe on the hind foot are longer than those ^ 
inside of the same toe, or on the outside of the third toe. On none of the other toes ls ^ oU ^ 
any distinct free margin. Tail scales all keeled, except at the extreme base; they ar ® V na [ 
the same size as the hack scales, and are arranged in rings ; the keels form l° n » , p 
lines below the tail, but not above ; at each side of the tail close to the base is a ia - 
of spinose scales. _ _ fn y0U ng 
Colour above pale slaty-grey, nearly uniform or speckled with whitish, or, ^ 
individuals especially, with three or four dark crossbands on the body. Ia some < ^ 
back is tinged in parts with pale copper red. Dusky crosshands on the limbs and ^ j ie UIlC ler 
middle of the tail, about 1*5 inch from the end, two or three dusky bands pass rount 
surface ; these are sometimes nearly black, at other times so faint as to be barely nC yev 
but they are not entirely absent in any of the specimens collected; end of the g0 
black. Lower parts white throughout, except the bands round the tail. Dehint a ^ c h 
as to be partly concealed by the fore limb when laid back along the body, there is a ^ T he 
at each side ; this in the living animal is said by Dr. Stoliczka to be bordered by 
red colour has faded greatly in spirit, hut can still be detected.
