The H..cap alpha.. emission line of B340 has broad, shallow wings that appear to be a distinct and unusual component of the broad line profile. We suggest that these wings may result from electron scattering in a hot (approx.10/sup 7/ K) gas that confines the clouds producing the broad line photons. Possible observational tests involve the polarization of the H..cap alpha.. wings, the soft X-ray emission from the hot gas, X-ray absorption by highly ionized iron, and either copious infrared emission or variability in the shape of the H..cap alpha.. wings.
