Abstract
HD 2I(4)8(4), a hitherto neglected eighth-magnitude late-type star near the Taurus/Cetus boundary, is shown to be a spectroscopic binary with quite a high eccentricity (o . 55) and a period of four years. Indirect evidence pe rmits a guess that the spectral type of the observed component is about K2 III and that its unseen companion (if not itself a binary system) is an F/G main-sequence star.
