412 MR. G. A. BOULENGER ON THE VARIETIES OF 
in contact with the upper postocular!; occipital usually broader and as long as or 
longer than the interparietal, sometimes fused with it; supratemporal sometimes large, 
sometimes broken up into scales; temporal scales granular, not much larger than dorsals; 
tympanic shield present ; masseteric shield moderately large, or small *, or absent ; four 
or five, rarely six, upper labials anterior to the subocular °. 
Collar with even edge, with the plates usually small, 7 to 13 in number; 26 to 39 
scales and granules in a longitudinal series between the symphysis of the chin-shields 
and the median collar-plate ; gular fold usually distinct. 
Dorsal scales smooth, granular and feebly convex, roundish-hexagonal and flat on the 
posterior part of the back, a little larger on the back than on the flanks; 62 to 78 scales 
across the middle of the body; 4 and 5 transverse series (rarely 4 or 3 and 4) correspond 
to one ventral plate, 30 to 56 to the length of the head. Ventral plates in 6 
longitudinal and 24 to 28 transverse series. Preanal plate rather large, with a single 
semicircle of small plates, rarely with two. 
Scales on upper surface of tibia minute, smaller than dorsals, hkewise smooth ; 
19 to 26 femoral pores on each side; 26 to 31 lamellar scales under the fourth toe. 
Caudal scales longer and shorter in alternate whorls, the upper feebly keeled, 
sometimes even nearly smooth, truncate behind; 28 to 40 scales in the fourth or fifth 
whorl behind the postanal granules. 
Greyish, yellowish brown, or dull green above (Pl. XXIII. fig. 5), sometimes bright 
green according to L. Miiller, with a more or less developed wide-meshed brown or 
blackish network, or blackish with round pale olive spots; small blue spots may be 
present on the sides: this form has lost all trace of striation, even in the young, 
Upper surface of head more or less spotted or vermiculate with black. Lower parts 
greyish or greenish white, salmon-pink, or copper-red, with or without small black 
spots ; a series of green or blue spots on the outer row of ventral shields. Markings 
on the tail absent or ill defined in the adults (Pl. X XIX. fig. 7).
