A velocity separation of stars and gas in Carina In the Carina spiral feature near galactic longitude of 290 deg, asignificant difference of 10-20 km/sec is observed between the motionsof the young stars and neutral hydrogen gas. The region of theseanomalous motions may extend from 3 to 7 kpc from the sun and is only 2deg wide in longitude. This region may best be described as a narrowsheet, particularly since the extent in latitude is uncertain. Twopossible interpretations of the optical and radio evidence for spiralstructure would place this peculiar region either on the inner side ofthe spiral feature or along the central axis of the optical spiral arm.The observed velocity anomaly has the right sign and a reasonableamplitude for a shock-front effect, and the applicability of Roberts'sshock-wave model of spiral structure to this anomalous region isdiscussed.
