Cometary HII regions are characterized by a strong edge--brightened core (the ``head'') with a low surface brightness ``tail'' of emission trailing off opposite the bright edge. We present multiple configuration, 15 GHz VLA continuum observations of the HII region G29.96-0.02. This source has been previously morphologically classified as ``cometary'' by various investigators. Our data, which are more sensitive to low surface brightness extended emission than any previous observation of this source, show a complex structure. The ~ 5'' edge--brightened core of the HII region is embedded in low level emission extending over ~ 15''-25''. Filamentary--like structures are observed perpendicular to the symmetry axis of the head, suggestive of an asymmetrically edge--brightened shell source. Additional filamentary--like structures are seen as far away as ~ 35'' from the core. These observations are inconsistent with existing models for cometary HII regions. Interpretation in terms of a new photo--evaporation model will be discussed.
