The idea of a new class of radio pulsars which have abnormally weak magnetic fields and which are distributed around the galactic center is proposed. The lack of observed short pulse periods in the galactic bulge X-ray sources indicates either that the pulsar magnetic fields are weak enough not to disrupt accretion disks and so produce an observable modulation, or that the periods are short enough to be smeared out by the electron scattering region which appears to surround at least some of the sources. The number of observed Population II pulsars is used as evidence to support the existence of the new class of pulsars.
