Scientific paper

Previous observations of long-period Cepheids in the Crux-Centaurus-Circinus-Norma (CCCN) region (bounded by galactic longitudes of approximately 294 and 331 deg) are used to delineate spiral features that are consistent with available data for other spiral tracers, especially H I gas. The galactic distribution of the long-period Cepheids in the CCCN region is examined, and a possible interpretation of the spiral structure as viewed in the CCCN region is suggested. Specifically, it is concluded that: (1) the region that is often called the Centaurus link contains no Cepheids with periods longer than 11.25 days and may be part of a spiral feature characterized by older Population I material; (2) long-period Cepheids at large distances (4 kpc) are concentrated near 307 deg galactic longitude and are probably associated with the 'inner arm' identified by Kraft (1965); and (3) the velocities of the observed Cepheids differ significantly from the predictions of the Schmidt (1965) model.
