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. tachydromotdes and 
T. sexlineatus, as observed by Giinther 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.”’
