  We present results based on the analysis of optical spectra of the
Narrow-Line Seyfert 1 (NLS1) galaxy KUG 1031+398, for which evidence was
reported of a line-emitting region "intermediate" (both in terms of velocity
and density) between the conventional Broad and Narrow Line Regions (BLR and
NLR, respectively). From our observations and modeling of the spectra, we get a
consistent decomposition of the line profiles into four components: an extended
H II region with unresolved lines, two distinct Seyfert-type clouds identified
with the NLR, and a relatively narrow "broad line" component emitting only
Balmer lines but no forbidden lines. Therefore, although we find this object to
be exceptional in having line-emission from the BLR with almost the same width
as the narrow lines, our interpretation of the data does not support the
existence of an "intermediate" line region (ILR).
