Journ. Asiat. Soo. Bengal, 1854, xxii, p. 652. 
Body slender, head short, obtuse and rather flattened above ; no 
gupranasals ; lower eyelid with a transparent disk in the middle. Shields of 
the head regular, anterior frontal in contact with the rostral and vertical, which 
is much attenuated posteriorly ; posterior 1'rontals small, aud not in contact, 
unless exceptionally ; 4 supraciliaries ; posterior pair of occipitals about 
twice the size of the anterior, middle shield small, shaped like the vertical, 
but shorter ; 3 to 4 pairs of elongate transverse shields behind the oc- 
cipitals ; 2 loreals and 2 pre-oculars, each pah- sometimes united into one 
vertically, or horizontally, elongated shield ; 7 upper labials followed by two 
smaller shields, the 5th under the orbit, but not much elongated ; 8 lower 
labials, the last smallest ; anterior chin-shields enlarged ; ear small rounded, 
generally with 2 or 3 small projecting shields on the front-, and a few still 
smaller lobules on the hinder, edge. Seales generally in 24 longitudinal series, 
and in 46 transverse series between fore and hind-limb ; these numbers vary 
very little ; young specimens have occasionally only 44, but the largest never 
appear to have more than 48, transverse series. A pair of large preanals. 
Subcaudals also enlarged, except the first few. The fore foot reaches to the 
anterior angle of the orbit, when laid forward, and the hind foot is three 
fifth the distance between fore and hind-limb. Palm and sole tubercular ; 
fourth finger barely longer than the third ; fourth toe nearly a quarter longer 
than the third. 
Colour , above, bronze brown, (sometimes with an olive tinge and a metallic 
lustre dining life,) uniform, or with three to five irregular series of small dark 
brown dots, the centre ones often arranged into dark lines ; sides darker, near 
the back more or less blackish brown, commencing with a dark band at the 
rostral shield. Above, at the edges of the hack, the black is margined by 
a somewhat indistinct pale line or band, occasionally dissolved into more or 
less confluent white spots ; below, there is also an indistinct pale, undulating, 
hand, passing from the ear to near the loin ; the upper portion of the sides is 
less, the lower more numerously, spotted with white ; the brown, as well as 
the somewhat indistinct whitish, spots extend on to the sides of the tail. Tipper 
labials whitish, spotted with brown. Chin uniform greenish white in young, 
spotted with greenish dusky in older specimens. Yent below greenish white, 
on the posterior part, but especially between the femora and below the tail, 
reddish, this colour being more or less bright according to sex and season. 
The brown spots on the back are very variable, both hi number and distinct-
