<p>Assam Keelback is said to be a "real khilonjia" or indigenous snake species as it is endemic to the ecologically rich Northeast.</p>.<p>It, however, was last seen in 1891, when the Britishers started expanding tea plantation in Sivasagar, the capital of the erstwhile Ahom Kingdom in upper Assam. Almost 129 years down the line, a team of researchers have re-discovered the snake species inside a reserve forest in Arunachal Pradesh, during their attempt to retrace the infamous Abor Expedition.</p>.<p>The British soldiers had carried out the expedition in Arunachal Pradesh more than 100 years ago and had killed several people belonging to the Abor community as a revenge for killing an officer in neighbouring Assam. </p>.<p>"Our effort was to retrace the historical Abor Expedition that was done 100 years back starting from Kobo Chapori to Gelling area of Arunachal Pradesh. We wanted to see how many species we can record, those were documented 100 years back after so much of changes that happened," Abhijit Das, one of the researchers of Dehradun-based Wildlife Institute of India (WWI) told DH on Monday.</p>.<p>David J.
