The group of short period Mira variables (periods less than 200 days) is thought to be a mixture of metal poor stars and disk stars. We have compiled JHKL photometry for 159 stars in this period range, the great majority of the data coming from new observations. The photometry is used to separate metal poor from disk stars, following Hron (1991, A&A 252, 583), and to define volume limited subsamples. Distances were derived from the K-magnitudes and the period/K-luminosity relationship.
