  Tayal and Zatsarinny [Astrophys. J. 850 (2017) 147] have reported results for
energy levels, radiative rates (A-values), lifetimes, and effective collision
strengths ($\Upsilon$) for transitions among 202 levels of C-like O~III. For
the calculations they have adopted the multi-configuration Hartree-Fock (MCHF)
code for the energy levels and A-values, and B-spline $R$-matrix (BSR) code for
$\Upsilon$. Their reported results cover a (much) larger range of
levels/transitions than generally available in the literature, and appear to be
accurate for energy levels and A-values. However, the magnitude and behaviour
of $\Upsilon$ do not appear to be correct for several transitions. We
demonstrate this through our independent calculations by adopting the flexible
atomic code (FAC) and recommend a fresh calculation for this important ion.
