rounded, as high as wide, with the posterior extremity rectangular 

 and sUghtly produced backwards on the upper side of the head. 

 2. A pair of anterior nasals, irregularly quadrangular, united by a 

 suture, and forming the upper margin of the nostril. 3. A single 

 anterior frontal, pentagonal, with the lateral angle in contact with 

 the posterior nasal ; its posterior side is very short. 4. A pair of 

 posterior frontals with a single shield between ; the former are irregu- 

 larly elliptical, and form a suture with the loreal ; the latter is narrow, 

 oblong. 5. Three pairs of parietals, one behind the other, and 

 occupying the space between the orbits. 6. The occipital region is 

 covered by many small irregular shields. 7- The upper eyelid has 

 two semi-elliptical shields, surrounded by granulations. 



Of the lateral shields of the head the posterior nasal is mentioned 

 above ; it is in contact posteriorly with the very large loreal, which 

 reaches to the orbit, occupying nearly the whole loreal region ; four 

 smaller shields form the lower margin of the orbit. There are five 

 rather narrow upper labial shields with several small ones behind. 



The lower jaw has a slightly convex anterior labial, and four lateral 

 ones, the third of which is as long as the others together. There is 

 a single pentagonal chin-shield between the first two labials, forming 

 a straight transverse suture with the front labial. Two series of 

 shields arise from its two posterior sides, parallel to, and broader than, 

 the series of the lower labials ; each is formed by five shields. The 

 throat, before the folds, is covered with granular scales. There are 

 the two folds, characteristic of the genus, with the series of shields 

 between. 



The back and the sides of the body are covered with minute 

 granular scales, arranged in regular cross series. The ventral shields 

 form six longitudinal and twenty-four transverse rows. A triangular 

 space before the vent also is shielded. The scales of the tail are 

 oblong, strongly keeled, arranged in regular rings. 



The fore-leg reaches to the extremity of the snout, if laid for- 

 wards. The third and fourth fingers are equal in length, then follow 

 the second, the fifth, and the first ; its anterior side and the fingers 

 are covered with one-rowed imbricate shields, those of the fore-arm 

 being the largest. The posterior extremity reaches to the posterior 

 margin of the orbit, if laid forwards. The relative length of the toes 

 does not differ from other species of the genus. The interior side 

 of the limb and the upper parts of the foot are shielded, the re- 

 mainder being granular. The shields of the upper leg form three 

 rows, those of the lower are larger and form two only ; all are imbri- 

 cate. The series of femoral pores is composed of twenty foramina. 



The ground colour of the upper parts is greenish-olive, irregularly 

 and indistinctly speckled with darker. A greenish-white stripe runs- 

 from the muzzle along the vertebral line towards the middle of the 

 tail, where it is gradually lost. A little before the eye, and distinctly 

 from the eye begins a black lateral band, edged with greenish-white 

 to the hip, and is lost soon after it has reached the side of the tail. 

 The lower parts are uniformly greenish-white. 



A single specimen is in the collection.
