For ＄0<P<1＄ the notion of ＄P＄-quasihyponormal operators on a Hilbert space is introduced and studied. lt is proved that if ＄T＄ is a p-quasihyponormal operator with polar decomposition ＄T=U|T|＄ then the operator ＄|T|^{1}/2U|T|^{1}/2＄ is quasihyponormal for ＄1/2￥leqq P<1＄ and it is ＄(P+(1/2))＄ -quasihyponormal for ＄0<＄ ＄P<1/2＄ .
