Meaning
Duodecim is twelve; duodenarius is a twelvefold grouping or number; duodenarii marks multiple such groups. Principes names rulers, not a second term for every ordinary soul.
Use in the book
Ficino announces a temporary conversation with the Pythagoreans before elaborating a hierarchy of twelve ruling souls within each of twelve spheres. His examples connect twelve zodiacal figures at the outermost sphere with twelve modes of human life at the innermost. The latter derive from the rankings and pairings of reason, anger, and desire. The numerical scheme then gathers many souls under principal souls, sphere-souls, and world-soul, and ascends through minds toward unity. The text itself qualifies the account: IV.1.52 says “perhaps” when discussing twelve ruling minds above, and ends by leaving the Pythagorean conversation for the stated Platonic order. Twelve is therefore not a number to impose indiscriminately on every class mentioned in the book. Nor does twelve cosmic spheres contradict eight heavens, since four elemental spheres are also counted. Numerical organization serves the account of unity governing multiplicity.

Translation in this edition
The number belongs to an explicitly introduced and closed Pythagorean conversation. Forte at IV.1.52 qualifies twelve ruling minds. The sixth human three-faculty ranking depends on context; its parum/paulum wording is not independently a confirmed translation error.
colligere / reducere
colligere / reducere. Printed forms: colligenda; reducamus; reducenda.
To gather or bring many under a smaller governing order. Multitude is reduced through a few ruling souls and sphere-souls toward one world-soul; this is hierarchical organization, not physical mixing. References: IV.1.41, IV.1.50. See Twelve.
recurrere in duodenarium
recurrere in duodenarium. Printed forms: recurrit rursus in duodenarium.
To return to a twelvefold grouping. A sphere-soul selected from twelve is said to organize subordinate souls in a corresponding twelvefold pattern. References: IV.1.42. See Twelve.
