  We measured the ionized-gas and stellar kinematics along the major and minor
axis of a sample of 10 early-type spirals. Much to our surprise we found a
remarkable gas velocity gradient along the minor axis of 8 of them. According
to the kinematic features observed in their ionized-gas velocity fields, we
divide our sample galaxies in three classes of objects. (i) NGC 4984, NGC 7213,
and NGC 7377 show an overall velocity curve along the minor axis without
zero-velocity points, out to the last measured radius, which is interpreted as
due to the warped structure of the gaseous disk. (ii) NGC 3885, NGC 4224, and
NGC 4586 are characterized by a velocity gradient along both major and minor
axis, although non-zero velocities along the minor axis are confined to the
central regions. Such gas kinematics have been explained as being due to
non-circular motions induced by a triaxial potential. (iii) NGC 2855 and NGC
7049 show a change of slope of the velocity gradient measured along the major
axis (which is shallower in the center and steeper away from the nucleus), as
well as non-zero gas velocities in the central regions of the minor axis. This
has been attributed to the presence of a kinematically-decoupled gaseous
component in orthogonal rotation with respect to the galaxy disk, namely an
inner polar disk. The case and origin of inner polar disks are discussed and
the list of their host galaxies is presented.
