of the tail intermixed with larger keeled tubercles. The ventral 

 scales are larger, tubercular, and feebly keeled. No chin-shields 

 behind the median pair. The tubercular plates under the basal 

 phalanx of all the digits much more developed. The ground-colour 

 of the upper parts darker than in G. deccanensis, chestnut-brown. 

 Hob. South Canara ; plains and up to 5000 feet.

Crown of head behind the eyes finely granular, the scales in 

 front being larger; 11 upper and 10 lower labials; three pairs of 

 chin-shields. Back granular, with about 30 longitudinal rows 

 of tubercles contained within an area bounded by faint keels 

 margining the belly. Enlarged praeanal and femoral scales, but no 

 pores. Colour above vinous brown ; a white semicircular line 

 joins the superciliary ridges ; a second horseshoe-shaped white line 

 runs from the gape below the ear to the opposite side, enclosing a 

 nuchal collar ; behind the collar two closely approximated white 

 lines run along the spine, becoming soon broken into spots merely ; 

 on the sides are more white spots, tending to form three distinct 

 lines, the lowest of which coincides with the ventral keel ; belly 

 whitish.

 ear-opening; forehead concave; ear-opening small, suboval, hori- 

 zontal. Body and limbs moderate ; digits short, cylindrical in their 

 basal, compressed in their distal portion, with well-developed 

 tubercle-like plates inferiorly. Head covered with small granules, 

 largest on the snout ; rostral quadrangular, not twice as broad as 

 deep ; nostril pierced between the rostral, the first labial, and 

 several small scales ; 10 or 11 upper and 9 lower labials ; mental 

 triangular ; two or three pairs of chin-shields, median largest and 

 forming a long suture behind the point of the mental. Upper 

 surface of body covered with small granules intermixed with 

 numerous small trihedral tubercles. Abdominal scales rather 

 small, cycloid, imbricate, smooth. Males with 3 or 4 praanal 

 pores. Tail cylindrical, tapering, rather swollen, covered with 

 roundish smooth scales, which are small and subimbricate above,
