Binary radio pulsars PSR 0655+64 and PSR 01913+16 are found to have short orbital periods (less than 25 hours), and high mass functions, indicating companion masses of 0.8 solar mass. Binary radio pulsars PSR 0820+12 and PSR 01853+29 have long orbital periods (greater than 120 days) and low, identical mass functions, suggesting companion masses of 0.2 to 0.4 solar mass. On the basis of this, it is suggested that two classes of systems are formed by the later evolution of binaries consisting of a neutron and a companion star. In the first category, the companion star is considerably more massive than the neutron star, and in the second, the neutron star is more massive than the companion. Mass transfer from a more massive, evolved companion star is found to be unstable, and to result in a short orbital period, whereas mass transfer from an evolved companion which is less massive than the neutron star is found to be stable, resulting in expansion of the orbit.
