80 SAURIA. 



With regard to its altitudinal extent, it is not found beyond an elevation of 8000 feet*. 

 Cantor says that it is " exceedingly numerous in the hills and valleys of the Malayan 

 countries. They may be seen basking in the sun, in bamboo hedges, or on trees ; and they 

 fearlessly enter houses in pursuit of insects, in which they display great agility. The female 

 deposits six to twelve yellowish-white, oval, cylindrical eggs, half an inch in length." 

 I have seen examples from 14 to 16 inches long, the trunk measuring 6 inches. The view 

 of the head (Plate X. fig. B) is taken from a Madi-as specimen. 



Having the typical specimen of Plestiodon sikkimensis before me, I have been enabled to 

 convince myself of its identity with E. rufescens. 



Tiliqua trivittata (Gray, Ind. Zool. c. fig., and Jerd. Journ. As. Soc. Beng. xxii. p. 478) 

 appears to be a variety of this species ; it has a third, well-marked whitish vertebral band, 

 besides the two others running along the sides of the back. Mr. Jerdon procured his 

 specimens at Jalnat, where it is the common species. 



EUPREPES MONTICOLA. (Plate X. fig. C.) 



A pair of contiguous supranasal shields ; postfrontals forming a broad suture together ; 

 vertical rather elongate, tapering behind. The fifth upper labial is below the orbit, and 

 much longer than high ; opening of the ear rather small, with lobules in front. Each scale 

 with only two rather prominent keels ; scales in thirty-four longitudinal and in thirty trans- 

 verse series. Prseanal scales not enlarged ; subcaudals rather larger than the others. Limbs 

 of moderate strength ; the third hind toe is one-fifth shorter than the fourth. 



Upper and lateral parts greenish olive, with a light band running along each side of the 

 back ; back with small black spots ; some scales on the sides with a white, black-edged 

 ocellus. A white longitudinal streak edged with black below the orbit. Lower parts 

 greenish white. 



This species is found in Sikkim, at an altitude of above 8000 feet, where it represents the 

 E. rufescens of the lowlands, from which it may be distinguished by its scales, which have 

 two keels only. An adult female specimen is 8^^ inches long, of which the tail takes 5. 



EuPREPES OLiVACEUS. (Plate X. fig. D.) 



Dasia olivacea. Gray, Ann. k Mag. Nat. Hist. ii. p. 331. 



Euprepes ernestii, Bum. i^ Bibr. Erpet. gen. v. p. 696. Cantor, Mai. Rept. p. 47. 



A pair of small supranasal shields ; the single prsefrontal forms a suture with the rostral, 



* My former assertion that this species occiu's at between 8000 and 10,000 feet in the Himalayas is 

 incorrect, as the specimens on which that opinion was founded, on a more careful examination, prove to 

 belong to a species closely allied to, but different from, Euprepes rufescens (Proc. Zool. Soc. 1860, p. 167).
