					<para>
    We report lambda-18 cm VLBI observations made in 1991 September of a
    further 25 objects from the first Caltech-Jodrell Bank VLBI Survey
    (the CJ1 survey). The CJ1 sample is a complete, flux-density limited
    sample of 135 radio sources with total flux density at lambda-6cm
    between 0.7 and 1.3Jy. These observations complete the lambda-18cm
    part of the survey. Together with the results of Paper I (Polatidis et
    al., &lt;J/ApJS/98/1>), we have now observed 81 CJ1 sources at
    lambda-18cm. Later papers in the series will present lambda-6cm
    observations and the analysis and interpretation of the results.</para></abstract>
