Abstract: The variations on a theme of locality for a pair of operators $ (H,K)$ on a $ {C^\ast}$-algebra $ \mathfrak{A}$ are expressed algebraically. If $ K$ is a $ \ast$-derivation generating an action of $ \mathbb{R}$ on $ \mathfrak{A}$, and $ H$ is $ \ast$-linear and $ K$-local, then, under certain restrictions, $ H$ is shown to be very closely related to $ K$.
