of the scales on the lower surfaces of the digits of both hands and 

 feet at once separates this species from &. hendulli, in which 

 they are entirely covered with small transverse lamellae, while in 

 this species, though the basal and terminal phalanges have trans- 

 verse lamellae, the intermediate one is covered with small irregular 

 scales. There is a large oval plate at the articulation of the basal 

 and proximal phalanges, as in G. hendalli. TJjjper surfaces 

 covered with minute granules, intermixed on the body with 

 irregularly arranged small tubercles, with slight keels. Eostral 

 large, quadrangular, not twice as broad as high, with median cleft. 

 Nostril between the rostral and several small scales. Nine to 

 thirteen upper and nine to eleven lower labials. . Symphysial very 

 large, subtriangular. Two large chin-shields ; two or three mental 

 scales following the symphysial are slightly enlarged. Abdominal 

 scales very small, juxtaposed, convex, keeled. Male with five to 

 seven prteanal pores, arranged in an obtusely angular or crescent- 

 shaped line. Tail cylindrical, slender, with small keeled scales and 

 some small pointed tubercles ; but in noue of the four specimens 

 examined are there the series of large spines which are to be seen 

 in some specimens of O. Tcendalli. 



Colour (from life). Iris orange or yellow. Above yellowish 

 brown, mottled with dark brown, deepest (rich red-dark-brown) 

 on the shoulders. Pive transverse yellow bands, two anterior 

 very bright, three posterior more or less indistinct in some 

 specimens ; the tubercles on the two anterior yellow bands are of 

 a most brilliant golden colour. Below, head and throat bright 

 orange, remainder purplish-grey, shading to buff on chest and 

 extremities of limbs. Tail with alternate bands of light and dark 

 brown ; in one specimen there are sixteen of these bands, and the 

 tubercles on the lighter bands are white. The sexes seem to be 

 coloured alike.

Locality. I found these Geckos in March 1896, numerous in two 

 small caves in the rocks at the " Crag," Peuang, at an elevation of 

 2200 feet : in which they were to be found running over the walls 

 both by day and night ; at dusk they could also be found on rocks 

 in the open. They are very active. 



Four specimens, three males and one female, are now in the 

 British Museum. 



Hnh. Malay Peninsula.
