  We present the first 3D observations of a diffuse elliptical galaxy (dE). The
good quality data (S/N up to 40) reveal the kinematical signature of an
embedded stellar disc, reminiscent of what is commonly observed in elliptical
galaxies, though similarity of their origins is questionable. Colour map built
from HST ACS images confirms the presence of this disc. Its characteristic
scale (about 3 arcsec = 250 pc) is about a half of galaxy's effective radius,
and its metallicity is 0.1-0.2 dex larger than the underlying population.
Fitting the spectra with synthetic single stellar populations (SSP) we found an
SSP-equivalent age of 5 Gyr and nearly solar metallicity [Fe/H]=-0.06 dex. We
checked that these determinations are consistent with those based on Lick
indices, but have smaller error bars. The kinematical discovery of a stellar
disc in dE gives additional support to an evolutionary link from dwarf
irregular galaxies due to stripping of the gas against the intra-cluster
medium.
