This paper discusses in conjugate-Normal and s-conjugate-normal

matrices. Conjugate-normal matrices play the same important role in

the theory of unitary congruence as the conventional normal matrices do

with respect to unitary similarities.we give a survey of the properties of

these matrices and s-conjugate-normal matrices.Also we consider some

equivalent conditions on s-conjugate-normal matrices.
