We describe an on-going HST program aimed at determining the
relationship between the nuclear black hole mass and bulge mass in
spiral galaxies. We have selected a volume limited sample of 54 nearby
spiral galaxies for which we already have ground based emission line
rotation curves, CCD surface photometry and radio maps. We are now
obtaining HST/STIS longslit observations of each of the galaxies in
the sample in order to determine the nuclear Halpha rotation curve at
high (approximately 0.1 arcsec) spatial resolution. We will use these
data to measure the unresolved dark mass concentration at the nucleus
of each object. Here we show the first results from observations of
objects in the sample.
