Relative abundance and body size were compared among six primate genera found from the Pondaung Formation (latest middle Eocene, Myanmar). <i>Pondaungia</i>, consisting of two species, is the most common primate in the Pondaung fauna. A high abundance of <i>Pondaungia savagei</i>, the larger species, is recorded at the northern fossil localities (Mogaung area). At the southwestern localities (Bahin area), the primates are taxonomically more diverse than in the other areas, and there are no significant differences in abundance of the amphipithecid genera, <i>Myanmarpithecus</i>, <i>Amphipithecus</i>, and <i>Pondaungia</i>. The body sizes of the three eosimiid taxa (<i>Eosimias</i>-like eosimiid, undescribed eosimiid, and <i>Bahinia</i>) and <i>Myanmarpithecus</i> are distinct from one another, but those of the <i>Amphipithecus</i> and <i>Pondaungia</i> species are inseparable. The postcranial bones of a large-sized primate (NMMP 20) from the Pondaung Formation, consisting of humeral, calcaneal, ulnar, and vertebral fragments, most likely belong to <i>Pondaungia cotteri</i> or <i>Amphipithecus mogaungensis</i>, based on comparisons of body mass estimates of NMMP 20 with those of the taxonomically allocated dentognathic specimens. Although NMMP 20 was previously cited as <i>Pondaungia savagei</i>, we consider the current evidence to be insufficient to resolve its species or generic-level taxonomic assignment.<br>
