about fifty longitudinal series of scales. The hind limb extends nearly to the tympanum, if 

 laid forwards. Green, clouded with yellowish ; a series of large round purplish-brown spots 

 along each side of the back. Lips yellowish. 



This species is found in the Birman Empire (Pegu), Siam, Mergui, and in Ceylon. We 

 have received specimens from Gamboja and from Mergui. An old male measures nearly 

 24 inches, the tail taking 19 inches. The specimen in the Paris Museum is not full-grown. 



Calotes rouxii. 



Calotes rouxii, Dum. ^ Bibr. iv. p. 407. 



Two small groups of spines, separated from each other, on each side of the neck. A fold 

 in front of the shoulder. Tail compressed into a sharpish edge at its base, covered superiorly 

 with very large pentagonal scales. Scales on the sides of the body nearly as large as those 

 on the belly. Tail below with four longitudinal series of rhomboid, strongly keeled scales, 

 each terminating in a point posteriorly. Brownish, uniform or spotted with black. 



The exact locality whence this species has been obtained is not known, nor has the species 

 ever been identified by more recent observers. Jerdon enumerates a C. rouxii in his list of 

 the Reptiles of Southern India (Journ. As. Soc. Beng. xxii. p. 471) ; having seen a rough 

 figure of this species in the collection of drawings in the possession of W. EUiott, Esq., 

 I have come to the conclusion that this must be an undescribed species, having a pair of 

 isolated spines immediately behind the orbit and a black fold of the skin before each 

 shoulder. The male is represented as uniform blackish brovra, with yellow head and neck ; 

 the female brown, with irregular dark cross bands. I propose for this species the name of 

 C. elliotti. 



Mr. Blyth also has a C, rouxi from Biinna and Ceylon ; but this determination is as 

 incorrect as that by Mr. Jerdon, the lizard in question having a row of three or four spines 

 above the tympairum (see C. nigrilabris).

A single series of spines descending obliquely backwards above the tympanum ; the spines 

 at either end of the series are longer than those in the middle ; scales between eye and 

 tympanum small, of equal size. Dorsal crest much elevated, extending on to the end of 

 the trunk, gradually becoming lower behind ; gular sac but slightly developed ; a fold behind 

 the lower jaw. About thirty-two series of scales round the middle of the trunk, twelve of
