Songlin, a Sino-Tibetan language of China previously considered a Tibetan dialect, is missing from E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27/E28 ( Song, Cheng and Lin, Xin 2020 , Song, Cheng and Yingying Xie and Daqin Li and Zuowen Li 2019 ). It has approximately 1,000 speakers ( Song, Cheng and Lin, Xin 2020: 659 ) and is not closely related, let alone intelligible, to Tibetan or any other language in the vicinity ( Song, Cheng and Lin, Xin 2020 ). I wish to thank Andrew Hsiu for bringing this language to my attention.
