Radio and optical evidence for activity in the spiral galaxy NGC 4319 is presented. NGC 4319 appears to be one of the first spirals to exhibit double lobe radio structure outside of the nuclear regions. The optical data show that (1) the quasar M205 is connected to the nucleus of NGC 4319 and (2) that a similarly connected region on the opposite side of the nucleus is expanding towards us with V ≡ 103km s-1. It is suggested that the unusual Hα/[N II] λ6583 ratio (≤0.3) indicates that the entire central (7 kpc diameter) disk of NGC 4319 has been shock excited by this activity.
