Abstract: Spectral types are assigned to 13 'unidentified' Equatorial Infrared Catalogue 1 (EIC-1) sources from a study of their spectra in the wavelength interval 5200-8700 A. Their spectral types range from M4.5 to M6.5. We infer from a combination of the data on their [J -K] colours and optical spectra that these sources are stars of luminosity class III. EIC 258 has a [J-K] colour which is higher than the characteristic value for its spectral type by 0.2. The star is also found to be a variable.
