and piesent nine transverse series to the axilla, and twenty from the axilla 

 to the groin. The scales of the tail are similar. The abdominal scales 

 are smooth and parallelogrammic, being truncate behind, and are in six- 

 teen transverse rows between the axilla and groin. A rather wide space 

 posterior to the auricular meatus, and posterior to the axilla is covered 

 with granular scales. The larger and square scales of the throat are in 

 four transverse rows of two scales each. They are separated from the 

 cross-row that marks the axilla by two cross- rows, and are bounded by 

 some flat scales in front and at the sides. 



The internasal plate is a little wider than long. The frontonasals are 

 well in contact. The frontal is longer than wide. The frontoparietals 

 are as wide as long, and are regularly five-sided, the supraorbital side a 

 little longer than the others. The interparietal is nearly three times as 

 long as wide. The parietals are larger and their posterior border forms, 

 with that of the interparietal, a straight line. The posterior exterior bor- 

 der is excavated. The loreal is higher than long, and presents an obtuse 

 angle posteriorly between the two preoculars. Of these the superior 

 extends posteriorly over the eye, leaving three narrow superciliaries. 

 Three supraoculars, the posterior with a small round plate posterior to it. 

 Temporal scales rather large, smooth ; no free marginal meatal scales. 

 Seven superior labials ; six inferiors. A short symphyseal and a long 

 postsymphyseal, both undivided. Posterior to the latter two pairs of 

 large infralabials, touching on the middle line, followed by a large pair 

 of infralabials which are separated on the middle line, each of which is 

 followed by two large and some smaller scales. 



Limbs rather short, posterior feet elongate. The fingers reach to the 

 heel when both limbs are pressed to the side of the body, and the toes to 

 the middle of the humerus. The limbs are covered by large, smooth 

 scales, except on the posterior faces of the humerus and tibia, where they 

 are smaller, and on the posterior face of the femur where they are granu- 

 lar. The claws are present on all the digits and are curved. Second and 

 fifth fingers equal. Second toe longer than fifth, and fourth a good deal 

 longer than third. Seven femoral pores and two preanals on each side. 

 Preanal plates, seven. Of these six are marginal, a large one with a small 

 one on each side of it, on each side of the middle line. The seventh is 

 in front of the two median marginals, and is a large triangle. 



Color, olive-brown or grayish, shaded with blackish on the head. The 

 plates of the head have pale borders and centres, and the rostral and labial 

 plates are yellow, the latter with a dark brown spot in the centre. A 

 light (? yellow) band over the eye, and two rows of similar spots on the 

 temporal region. Several rows of similar dark-edged spots on the nape. 

 Granular region black, with yellow spots. The spots fade out on the 

 dorsal region, each cross-row of scales has a blackish edge. On the tail 

 two rows of such spots can be made out on each side. Inferior surfaces 

 pale, probably yellow ; lower labials, and the posterior infralabials with a 

 dark brown spot in the centre.
