The IRAS low-resolution spectrum of IRAS 81344 - 0632, which may be associated with the proposed (Cowan et al., 1989) very young supernova remnant G25.5 + 0.2, is presented. This spectrum shows a red continuum, and the 12.8-micron Ne II forbidden line, and is similar to the spectra of known compact H II regions and planetary nebulae. This, together with other results, suggests that IRAS 18344 - 0632 and G25.5 + 0.2 are associated, and are a planetary nebula not a young supernova remnant, although it is difficult to reconcile this identification with all available observations. 15 refs.
