I obtained this species at Muangla in the Sanda valley. The specimens, like those 

 from the Kashia Hills in the British Museum, have sixteen longitudinal rows of scales 

 from fold to fold, vphilst Blyth's Rangoon example of the species has only fourteen 

 such rows, and eight on the ventral surface, while the specimens from Muangla and 

 the Kashia Hills have ten rows of ventral scales. These specimens, and those in the 

 British Museum, have palatine teeth, but Blyth states that the Rangoon lizard had 

 none. Eight of the dorsal rows of the Muangla lizard are strongly and continuously 

 keeled, but the others are smooth. There are from 110 to 115 transverse rows from 

 the chin to the anus. The shields of the head, with the exception of the vertical, the 

 three occipitals, and the row of supra-orbitals, are variable in number. Among eight 

 specimens in the Indian Museum, Calcutta, no two are alike in respect of these shields.
