The ridge of active star formation in the H II region complex NGC 6334, which is associated with an elongated molecular cloud, has been mapped with the VLA. Six strong radio sources were detected at 6 cm, ranging in size from very compact (less than 0.3 arcsec) to extended (greater than 40 arcsec). The spatial distribution of the H II regions suggests that previous proposed evolutionary schemes are inadequate, as an extended H II region was detected at the northeast edge, usually assumed to be the less evolved section. Cloud shapes may be explained in terms of the hydrodynamic models for H II region evolution in gaseous environments developed by Bodenheimer et al. (1979). Observations of source NGC 6334(B), which has a brightness temperature greatly in excess of that expected for an optically thick H II region, at wavelengths of 20, 6, 2 and 1.3 cm show a flat spectrum and an angular size dependent on the square of the wavelength, similar to the compact source at the galactic center.
