The 352 MHz Westerbork In the Southern Hemisphere ( WISH ) survey is the southern extension of the WENSS , covering 1.60 sr between -9 \degr < \delta < -26 \degr to a limiting flux density of \sim 18 mJy ( 5 \sigma ) .
Due to the very low elevation of the observations , the survey has a much lower resolution in declination than in right ascension ( 54 \arcsec \times 54 \arcsec { cosec } \delta ) .
A correlation with the 1.4 GHz NVSS shows that the positional accuracy is less constrained in declination than in right ascension , but there is no significant systematic error .
We present a source list containing 73570 sources .
We correlate this WISH catalogue with the NVSS to construct a sample of faint Ultra Steep Spectrum ( USS ) sources , which is accessible for follow-up studies with large optical telescopes in the southern hemisphere .
This sample is aimed at increasing the number of known high redshift radio galaxies to allow detailed follow-up studies of these massive galaxies and their environments in the early Universe .
