HI in Virgo's "Red and Dead" Dwarf Ellipticals - A Tidal Tail and
  Central Star Formation
  We investigate a sample of 3 dwarf elliptical galaxies in the Virgo Cluster
which have significant reservoirs of HI. We present deep optical imaging (from
CFHT and KPNO), HI spectra (Arecibo) and resolved HI imaging (VLA) of this
sample. These observations confirm their HI content and optical morphologies,
and indicate that the gas is unlikely to be recently accreted. The sample has
more in common with dwarf transitionals, although dwarf transitionals are
generally lower in stellar mass and gas fraction. VCC 190 has an HI tidal tail
from a recent encounter with the massive spiral galaxy NGC 4224. In VCC 611,
blue star-forming features are observed which were unseen by shallower SDSS
imaging.
