of emission in the central region, and two ansae that are placed roughly along the major axis of the elliptical emission. Also, there is a larger faint halo that envelopes the inner structure.

Spectra acquired at three different positions on the nebula are shown in Figure 2, on the SE knot (NGC 3242SE), on the E section of the bright ring (NGC 3242E), and on the SW halo (NGC 3242H). The spectra are similar in all locations; the bright lines are present in all positions, along with stellar continuum at the shorter wavelengths. One difference is that the line at 2.189  are much brighter in the E ring than in the SE knot or halo position.

### NGC 6210

NGC 6210 is a fairly compact PN with a core – halo morphology similar to other ellipticals. Phillips & Cuesta (1996) performed a visible wavelength spectroscopic study that revealed a complex velocity structure which suggests multiple shells and possibly “jets” at various position angles. The near-IR image presented in Paper I does not reveal much of the structure. This PN is one of several in which Geballe et al. (1991) detected unidentified emission at 2.286  (but not at 2.199 ).
