Legion (taxonomy)

The legion, in biological classification, is a non-obligatory taxonomic rank within the Linnaean hierarchy sometimes used in zoology.

In zoological taxonomy, the legion is: Legions may be grouped into superlegions or subdivided into sublegions, and these again into infralegions.

Legions and their super/sub/infra groups have been employed in some classifications of birds and mammals.

Full use is made of all of these (along with cohorts and supercohorts) in, for example, McKenna and Bell's classification of mammals.
