From spectra taken at McDonald and Lick Observatories, velocities in the nucleus and in the outer emission knots of the barred spiral NGC 613 were measured. The recession velocity of the galaxy is + 1493 km/sec. From the steep velocity gradient across the nucleus a mass of 9 X 10 M0 for the nuclear region is determined. The northwest emission knots, 80" from the center, have velocities of the order of 150 km/sec with respect to the nucleus. The southeast emission knots have velocities which range from almost 0 (60" from the center) to 250 km/sec (100" from the center), with respect to the nucleus. To account for this strange velocity variation, various models are considered. It is suggested that NGC 613, like NGC 1097 and NGC 6951, is a type of "fat-bar" spiral, with a small nucleus and a large velocity of circulation in the nucleus, low rotation of the bar as a whole, and outer features reminiscent of spiral arms in ordinary spirals. For such a galaxy, the estimate of the total mass is highly uncertain.
