INTRODUCTION

The dataset for cerebellar weight or mass is given in two additional files. The first numerical file gives cerebellar weight or mass in tabular form, with 100 rows (species) and 7 columns. The second additional file reports 16 references, from which all of the numerical data were derived.  Note that 76% of the numerical data in the first additional file are derived from three works by H. Stephan and his colleagues (see second additional file).
