Habitat. Khasi hills, near Assam. Six specimens, from the collection of 

 Dr. T. C. Jerdon, are preserved in the British Museum. Jerdon referred them to 

 T. sexlineatus (Proc. As. Soc. Beng. 1870, p. 72). 



This species may be regarded as intermediate between T. tachydromoides and 

 T. sexlineatus , as observed by Gunther in 1888 : " Specimens of T. sexlineatus from 

 Khassya, in the British Museum, have on the whole a somewhat shorter and less 

 tapering snout, also shorter toes than the typical form, and approach in these 

 respects T. meridionalis." 



7. Tachydromus smaragdinus, Blgr.
