* 240¢-260¢ -- '''semifourth''' -- an interval of this size is around half the size of a perfect fourth.

* 440¢-468¢ -- '''semisixth''' -- an interval of this size is around half the size of a major sixth. [[Zhea Erose]] calls the 440c-464c region '''naiadic''' (from ''naiad'', a kind of ancient Greek water spirit) and uses it frequently.

* 440¢-468¢ -- '''semisixth''' -- an interval of this size is around half the size of a major sixth.

* 732¢-760¢ -- '''semitenth''' -- an interval of this size is around half the size of a major tenth (i. e., compound major third). Another possible name is sesquifourth (since this is also about one and a half times the size of a perfect fourth). [[User:IlL|Inthar]] proposes the name '''cocytic''' (from the Greek mythological Cocytus, the frozen lake or river in the underworld; chosen because it's an inverse naiadic).
