There is a growing consensus that the vast majority of ultra-diffuse galaxies ( UDGs ) are dwarf galaxies .
However , there remain a few UDGs that seem to be special in terms of their globular cluster ( GC ) systems .
In particular , according to some authors , certain UDGs exhibit large GC populations when compared to expectations from their stellar ( or total ) mass .
Among these special UDGs , DF44 in the Coma cluster is one of the better-known examples .
DF44 has been claimed to have a relatively high number of GCs , N _ { GC } = 74 ^ { +18 } _ { -18 } , for a stellar mass of only 3 \times 10 ^ { 8 } M _ { \odot } .
In this paper we revisit this number , and , contrary to previous results , find N _ { GC } = 19 ^ { +5 } _ { -5 } .
Making use of the M _ { GC } - M _ { halo } relation , this number of GCs suggests a dark matter halo mass of M _ { halo } = 1.0 ^ { +0.3 } _ { -0.3 } \times 10 ^ { 11 } M _ { \odot } , a value which is consistent with the expected total mass for DF44 based on its velocity dispersion , \sigma = 33 ^ { +3 } _ { -3 } km s ^ { -1 } .
We conclude that the number of GCs around DF44 is as expected for regular dwarf galaxies of similar stellar mass and DF44 is not extraordinary in this respect .
