  We compute the spatial velocity components and the galactic orbital elements
for 209 metal-poor $([Fe/H] < -1.0)$ RRLyrae (ab) variable stars in the solar
neighborhood using proper motions, radial velocities, and photometric distances
available in the literature. We observe abrupt changes in the stellar spatial
and kinematical characteristics when the peculiar velocities relative to the
local standard of rest cross the threshold value, $V_{\rm pec}\approx 280$
\mbox{km s$^{-1}$}. This provides evidence that the general population of
metal-poor RRLyrae stars is not uniform, and includes two spherical subsystems
occupying different volumes in the Galaxy. Based on the agreement between
typical parameters of corresponding subsystems of field RRLyrae stars and of
the globular clusters, studied by us earlier, we conclude that metal-poor stars
and globular clusters can be subdivided into two populations, but using
different criteria for stars and clusters. We suppose that field stars with
fast motion and clusters with redder horizontal branches constitute the
spheroidal subsystem of the accreted outer halo, with is approximately two
times larger in size than the first subsystem. It has absolutely no metallicity
gradients, most of its stars have eccentric orbits, many stars display
retrograde motion in the Galaxy, and their ages are comparatively low,
supporting the hypothesis that the objects in this subsystem have an
extragalactic origin.
