Abstract. We report new determinations of the radius
and mass of the pulsating helium­rich, hydrogen­deficient
star LSS 3184 (BX Cir) using measurements of radial ve­
locity and angular radius throughout its pulsation cycle.
Measurements of radial velocity, and thus changes in stel­
lar radius (\DeltaR ? ), were made using Anglo­Australian Tele­
