passes through the upper edge of the ear ; the number of longitudinal 

 rows of scales also appears to be slightly larger in the present species. 



MOCOA SlKKEMENSIS, Blyth. 



PI. v, figs. 2, 2<x, side and upper views of the head ; three times the natural size. 

 Journ. Asiat. Soc. Bengal, 1854, xxii, p. 652. 



Body slender, head short, obtuse and rather flattened above ; no 

 supranasals ; lower eyelid with a transparent disk hi the middle. Shields of 

 the head regular, anterior frontal in contact with the rostral and vertical, which 

 is much attenuated posteriorly ; posterior frontals small, and not in contact, 

 unless exceptionally ; 4 supraciliaries ; posterior pah 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 pair 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. Scales 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 during 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 back, 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, 

 band, 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. Upper 

 labials whitish, spotted with brown. Chin uniform greenish white in young, 

 spotted with greenish dusky in older specimens. Vent 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-
