The present velocity survey observed 150 carbon stars in the SMC in the near-IR with an individual precision of + or - 1.8 km/sec. Carbon stars are found to behave kinematically like the planetary nebulae system with which they share a velocity dispersion of about 27 km/sec; they also exhibit the same velocity dispersion as a sample of halo metal-poor giants near NGC 121. The carbon stars and planetary nebulae may belong to a spheroidal system, and indications are found of streaming motions in the wing section between the SMC and LMC. 26 refs.
