摘要：

Low-resolution spectra are presented for eleven faint, halo carbon stars, selected from previously published objective-prism candidates at high galactic latitude. Temperature and carbon classes are derived from these spectra. These objects are useful for studies of both the dynamics and chemical evolution of the halo and are observable at remarkably large galactocentric distances.
