Note 164 — Chapter XXXV · SUBCLASS DIPNEUSTI,[164] OR LUNGFISHES

This group has been usually known as Dipnoi, a name chosen by Johannes Müller in 1845. But the latter term was first taken by Leuckart in 1821 as a name for Amphibians before any of the living Dipneusti were known. We therefore follow Boulenger in the use of the name Dipneusti, suggested by Hæckel in 1866. The name Dipnoan may, however, be retained as a vernacular equivalent of Dipneusti.
