Spectra from sliding spark discharges between zinc electrodes and from a hollow-cathode source were photographed in the range 2105-1400 Å with the NBS 10.7 m vacuum spectrograph. New measurements of 130 Zn ii lines in this region, combined in some cases with previous measurements in the air region, were used to derive revised positions for the known levels. Wavelengths calculated from these levels are given for 267 lines in the region 2570-730 Å. The line list also includes unclassified Zn ii lines below 2570 Å, based on the most complete description of this spectrum [A. M. Crooker and K. A. Dick, Can. J. Phys. 46 , 1241 (1968)]. A few additions to the line list of Crooker and Dick above 2700 Å are given. The line and level lists take into account recent work at the National Bureau of Standards on the Zn ii analysis.
