HD 149404 (HR 6164) was noted to have double lines by Conti, Leep and Lorre (1977). The spectrum has been previously classified as 09Ia, and shows strong Si IV λ4089, 4116 absorption, He I stronger than He II, N III λ4634, 41 weakly in emission, He II λ4686 “filled in,” and all the Balmer lines through H13 in absorption except Hα, which is strongly in emission.
