• Wah blei is the right bank tributary of Kynshi river. Kynshi river is in news due to the Mawsmai cave where a microsnail species was discovered recently.  
• Mawsmai cave is situated in the small village of Mawsmai, around four kilometres from Cherrapunjee (Sohra) in the East Khasi Hills district of Meghalaya.  
• The term ‘Mawsmai’ means ‘Oath Stone’ in the Khasi language. The Khasi people use the local term ‘Krem’ for the cave. 

• The cave is located at an altitude of 1,195 metres above sea level and is indirectly influenced by the streams of the Kynshi river originating from the East Khasi Hills.
