Mean pulse profiles and polarization properties are presented for ninesouthern pulsars. The observations were made using the Parkes radio telescopeat frequencies near 1330 MHz; three of the nine pulsars were also observed at660 MHz. A very high degree of circular polarization was observed in PSRJ1603-7202. Complex position angle variations which are not well described bythe rotating-vector model were observed in PSRs J2124-3358 and J2145-0750, bothof which have very wide profiles. Rotation measures were obtained for all ninepulsars, with two implying relatively strong interstellar magnetic fields.Comment: 24 pages, 11 figs, accepted by Ap
