Letbe a quasinormal family of meromorphic functions onD, all of whose zeros are multiple, and let ϕ be a holomorphic function univalent onD. Suppose that for anyf∊,f′(z) ≠ ϕ′(z) forz∊D. Thenis quasinormal of order 1 onD. Moreover, if there exists a compact setK⊂Dsuch that eachf∊. vanishes at two distinct points ofK, thenis normal onD.
