The spectral structure of Thallium II was investigated last year by Smith, by Rao, Narayan and Rao, and by McLennan, McLay and Crawford. The 6s 21 S, 6s 7s 3.1 S, 6s 6p 3.1 P and 6s 6d 3.1 D terms were established by Smith and the authors with exact agreement. Rao, Narayan and Rao found these triplet terms, also 6s 5f 3 F0 , and tentatively 6s 21 S0 and 6s 7p 3 P2 0 . In all three communications the location of one or more components of a 6p 23 P term was suggested. The term notation used above was proposed by Russell, Shenstone and Turner. It has been employed throughout this paper.
