Abstract.

A spectrocospic survey in an area of 5 squares degrees, located in the general direction of the Palomar-Groningen Variable-Star Field 2 , yields 263 Giant M stars. A test of completeness shows than the survey was complete down visual magnitude 16 for early giant M stars and to visual magnitude 17 for late giant M stars. The space density distribution of the stars is presented.
