We provide high-speed ultrasound data on the four Mangetti Dune !Xung clicks. The posterior constriction is uvular for all four clicks front uvular for [g|] and [}] and back uvular for [g!] and [g{]. [g!] and [g{] both involve tongue center lowering and tongue root retraction as part of the rarefaction gestures. The rarefaction gestures in [g|] and [}] involve tongue center lowering. Lingual cavity volume is largest for [g!], followed by [g{], [}] and [g|]. A tongue tip recoil effect is found following [g!], but the effect is smaller than that seen in IsiXhosa in earlier studies.
