We have measured the absolute proper motions of four low-latitude , inner-Galaxy globular clusters .
These clusters are : NGC 6266 ( M62 ) , NGC 6304 , NGC 6316 and NGC 6723 .
The proper motions are on the Hipparcos system , as no background extragalactic objects are found in these high-extinction regions .
The proper-motion uncertainties range between 0.3 and 0.6 mas yr ^ { -1 } .

We discuss the kinematics of these clusters and of three additional bulge clusters — NGC 6522 , NGC 6528 and NFC 6553 — whose proper motions with respect to bulge stars had been determined previously .
We find that all of the clusters have velocities that confine them to the bulge region .
Of the three metal poor clusters ( [ Fe/H ] < -1.0 ) , NGC 6522 , and NGC 6723 have kinematics consistent with halo membership .
The third cluster , NGC 6266 however , appears to belong to a rotationally-supported system .
Of the four metal rich clusters ( [ Fe/H ] \geq - 1.0 ) , NGC 6304 and NGC 6553 also have kinematics consistent with membership to a rotationally-supported system .
NGC 6528 has kinematics , metallicity and mass that argue in favor of a genuine Milky-Way bar cluster .
NGC 6316 ’ s kinematics indicate membership to a hotter system than the bar .
