median occipital broadly oval, small, posterior occipitals very large. 

 A rather elongated supra-nasal ; nostril large, round, extending almost 

 over the entire height of the nasal ; two loreals, the posterior being 

 much the larger one, three small upper and two somewhat enlarged 

 inferior ante-oculars ; lower eyelid scaly ; seven low upper labials, 

 the fifth is the longest, situated below the eye ; ear moderately 

 open, its inner edge with minute tubercles ; lower rostral moderate, 

 the shield next posterior to it small, single, followed by two diver- 

 ging pairs of chin shields, very little larger than the rest ; seven 

 lower labials ; preanal edge occupied by scarcely enlarged 

 scales ; sub-caudals single conspicuously larger than the row of 

 smooth scales on either side. Scales in twenty-six longitudinal 

 rows round the body, large, the upper and lateral ones strongly 

 five carinated, the carinse continuing very distinctly on the scales of 

 the tail, giving the lizard a very ornamental but rough appearance ; 

 twenty-three transverse rows of scales between fore and hind limb ; 

 eight longitudinal rows of smooth scales on the belly. 



Colour above and on the sides dark brown, paler on the head, up- 

 per labials yellowish, a greenish iridescent narrow streak extends 

 from the supraciliary edge on each side of the humeral region poste- 

 riorly, another similar stripe begins at the end of the upper labial, 

 both are margined with blackish brown, and nearly entirely dis- 

 appear in about the middle of the body. There are besides two 

 narrow longitudinal darkish stripes observable along the centre of 

 the back, but they remain very indistinct ; very few of the lateral 

 scales are edged with greenish. Yellowish white below, with a 

 greenish iridescent tinge, especially conspicuous on the sides of 

 the neck and of the belly. 



The more depressed and triangular head, smaller number of scales 

 which are five carinated, and the differences in the frontals and colora- 

 tion readily distinguish this species from T, carinata, S c h n e i d. 



I have only obtained a single specimen of this beautiful species 

 on Camorta, (Nicobars), in the forest near the new settlement ; it 

 measures 4£th inches, of which the tail is 2f th inches. 



Steindachner (Novara Eeptilien, p. 48) describes from 

 the Nicobars an Euprepes macrotis, F i t z., which appears to belong to 

 the sub-division Euprepis, and is entirely distinct from the present
