Abstract
The oribatid species described by J. E. Hull between 1913 and 1918 are revised and 133 of his identifications made between 1913 and 1930 are reinterpreted. Of the taxa established by Hull, 10 genera are redefined; 10 species are redesignated from original descriptions; 12 species are synonymized from original material; three little-known species are redescribed from original material; and eight are declared species inquirendae.
