156 Lacertidie. 



Body not depressed. Head 2\ times as long as broad, its depth 

 equal to the distance between the centre of the eye and the tympanum, 

 its length 4^ times in length to vent ; snout acutely pointed, with 

 sharp canthus and nearly vertical loreal region, as long as postocular 

 part of head. Pileus 2^ times as long as broad. Neck a little 

 narrower than the head. Hind limb reaching the axil ; foot as long 

 as the head. Tail 2f times as long as head and body. 



Nostril pierced between 4 shields. Eostral entering the nostril ; 

 upper head-shields smooth : frontonasal longer than broad ; prefrontals 

 forming a median suture ; frontal shorter than its distance from the 

 end of the snout, If times as long as broad, narrower behind than in 

 front ; parietals nearly twice as long as broad ; interparietal 1^ times 

 as long as broad , occipital as broad as and shorter than the inter- 

 parietal, o supraoculars, first longer than second, and in contact with 

 the second loreal, third very small and narrowly separated from the 

 frontoparietal ; 5 superciliaries, second longest, all in contact with the 

 supraoculars. Nasal forming a very short suture with its fellow 

 behind the rostral and with the anterior loreal aliove the postnasal ; 

 anterior loreal shorter than second ; 4 or 5 upper labials anterior to 

 the subocular, which is as broad beneath us above. Temporal scales 

 very small, hexagonal, keeled ; two large upper temporals, keeled aliove, 

 first not in contact with the fourth supraocular ; a long and narrow 

 tympanic shield. 



4 pairs of chin-shields, the three anterior in contact in the middle. 

 26 gular scales in the median line, anterior narrow, juxtaposed, smooth, 

 posterior increasing in size, imbricate, pointed, strongly keeled and 

 passing gradually into the ventrals, there being no trace of a collar. 



Dorsal plates truncate and shortly mucronate behind, in 6 longitu- 

 dinal series on the neck and on the body. Ventral plates truncate and 

 shortly mucronate, strongly keeled, in Id longitudinal and 30 trans- 

 verse series ; no large scales bordering the ventrals. 32 plates and 

 scales round the middle of the body. Preanal plate large, bicarinate, 

 with smaller keeled plates on the sides. 



Upper surface of limbs with rhombic keeled scales. A single 

 femoral pore on each side.'' Sul)digital lamellae single, 22 under 

 the fourth toe. 



Caudal scales strongly keeled and shortly mucronate, the keels 

 forming six ridges on the upper surface of the l)asal part ; the whorls 

 nearly equal in length, the fourth containing IS scales. 



Reddish brown above, with a broad whitish streak on facli side 



* Giinther's statement that there are two pores is due to a misunderstanding" 

 of Anderson's description, which inoiitions " ono pnir of femoral pores."
