Let  G  be a finite  p -group and let Autc( G ) be the group of all central automorphisms of  G . Let    be the set of all central automorphisms of  G  fixing  Z ( G ) elementwise. For a finite  p -group of class 2, we have   . In [6] we proved    if and only if  Z ( G ) is cyclic. In this paper we first prove that there is no finite  p -group of class 2 for which   , and then we characterize the finite  p -groups  G  satisfying   . As a consequence, we prove the main results of Curran and McCaughan [2].
