The mass distribution of the primary component and orbit major semiaxis a is investigated for the case of 482 eclipsing binaries with primaries of a known spectral type and luminosity class. It is determined that the number of stars per unit interval of log a is deficient by comparison with wider systems, through consideration of the parameter domain where log (primary component mass/solar mass) is greater than about 0.45, and log a/solar radius is less than about 1.0.
