  1. Species median measurements are provided for cerebellar, cerebral, and ansiform volumes (in mm3). Species ratios between median cerebellar and cerebral volumes, and ansiform and cerebellar volumes are also given (in percentages). Importantly, these ratios are reported merely to illustrate how allometric scaling of cerebello-cerebral system components may lead to wide-ranging ratios reported in the literature. Species are ordered by the phylogenetic tree. For six species (Ateles paniscus, Homo sapiens, Macaca fascicularis, Macaca mulatta, Pan troglodytes, and Saimiri sciureus) more than four specimens were available. For these species, median absolute deviations are also reported (indicated in bold). Some specimens were recorded as outliers and removed before subsequent analyses. These include a crab-eating and rhesus macaque, which were outliers in their cerebellar and cerebral volumes, as marked by the asterisks.
