Thirty-six infrared objects have been identified from direct two-color image-tube photographs. Slit spectra in the 5800 Â to 8800 Â region have been obtained of each object. The sample consists of 35 M-type stars, one carbon star, and no S-type stars. Most of the M stars are probably semiregular and Mira-type variables.
