  BPS CS 22940-0009 is a helium-rich B-star that shares characteristics with
both helium-rich B subdwarfs and extreme helium stars. The optical spectrum of
BPS CS 22940-0009 has been analysed from SALT observations. The atmospheric
parameters were found to be $T_{\rm eff} = 34970 \pm 370$ K, $\log g/{\rm cm \,
s^{-2}} = 4.79 \pm 0.17$, $n_{\rm H}/n_{\rm He} \simeq 0.007$, $n_{\rm
C}/n_{\rm He} \simeq 0.007$, $n_{\rm N}/n_{\rm He} \simeq 0.002$, although
further improvement to the helium line fits would be desirable. This places the
star as a link between the He-sdB and EHe populations in $g$-$T$ space. The
abundance profile shows enrichment of N from CNO-processing, and C from
$3\alpha$ burning. Depletion of Al, Si, S and a low upper limit for Fe show the
star to be intrinsically metal-poor. The results are consistent with BPS CS
22940-0009 having formed from the merger of two helium white dwarfs and
currently evolving toward the helium main sequence.
