Description:
The results of a spectral classification of 257 M stars observed in
the Cepheus region are given. Their equatorial coordinates,
photographic stellar magnitudes, and spectral subtypes were
determined. These stars are giants and supergiants, in all
probability. None of them appear in a catalog of variable stars. It is
assumed that variability might be detected in many of them upon
further study. Fifty-two of the stars have been identified with
infrared sources.
In addition to the originally published data, magnitudes, positions,
cross-identifications and notes have been added in May 2002.

():
the list was matched against the IRAS, MSX, and Dearborn red-star
catalogues, and the coordinates were added, mostly from GSC-ACT (Cat.
I/255) or USNO-A2.0 (Cat. I/252); two stars (#46 and #174) could not
be recovered. Notes were added in the course of this work.
