  We present a list of 24 new blazar candidates selected in a search for
possible counterparts of spatial clusters of gamma-ray photons in the recent
9Y-MST catalogue, at energies higher than 10 GeV and at Galactic latitudes
higher than 20 degrees. 13 of these clusters are also included the preliminary
release of the 4FGL catalogue of gamma-ray sources. The search for possible
counterparts is based on the possible associations of the clusters with radio
sources within a circle having a radius of 6 arcmin. We then investigated the
possible optical or mid-IR associations of these sources, checking if they show
some properties typical of new blazar candidates.
