  We have identified three ultraluminous X-ray sources (ULXs) hosted by
globular clusters (GCs) within NGC 1316's stellar system. These discoveries
bring the total number of known ULXs in GCs up to 20. We find that the X-ray
spectra of the three new sources do not deviate from the established pattern of
spectral behaviour of the other known GC ULXs. The consistency of the X-ray
spectral behaviour for these sources points to multiple paths of formation and
evolution mechanisms for these rare and unique sources. Using the now larger
sample of GC ULXs, we compare the optical properties of the entire known
population of GC ULXs to other GCs across five galaxies and find that the
properties of clusters that host ULXs are quite different from the typical
clusters. Lastly, any trend of GC ULXs being preferentially hosted by
metal-rich clusters is not strongly significant in this sample.
