  Eighteen RR Lyrae variables (RRLs) that lie in the "$12\fh 4$ clump"
identified by the QUEST survey have been observed spectroscopically to measure
their radial velocities and metal abundances. Ten blue horizontal branch (BHB)
stars identified by the Sloan Digital Sky Survey (SDSS) were added to this
sample. Six of the 9 stars in the densest region of the clump have a mean
radial velocity in the galactic rest frame ($V_{\rm gsr}$) of 99.8 and $\sigma$
= 17.3 ${\rm km s}^{-1}$, which is slightly smaller than the average error of
the measurements. The whole sample contains 8 RRLs and 5 BHB stars that have
values of $V_{\rm gsr}$ suggesting membership in this stream. For 7 of these
RRLs, the measurements of [Fe/H], which have an internal precision of 0.08 dex,
yield $<{\rm [Fe/H]}> = -1.86$ and $\sigma$ = 0.40. These values suggest that
the stream is a tidally disrupted dwarf spheroidal galaxy of low luminosity.
Photometry from the database of the SDSS indicates that this stream covers at
least 106 deg$^2$ of the sky in the constellation Virgo. The name Virgo Stellar
Stream is suggested.
