  The SCUBA local universe galaxy survey is the first systematic survey of the
local universe at submillimetre wavelengths. We have observed ~200 galaxies
from the IRAS bright galaxy catalogue and the CfA optical redshift survey. The
IRAS sample showed that our estimate of the luminosity function was potentially
biased if a cold population of galaxies existed which would not have appeared
in the IRAS BGS but would have been detected in a SCUBA blind survey. Here we
present preliminary results from the optically selected sample which suggest
that this is indeed the case.
