Some ornithologists (Fiirbringer, Morph. und Syst. Vogel, p. 1565) place the Pygopodes 
between the Anseres and the Herodiones in an Order Pelargornithes, and regard the Tubi- 
nares and Impennes as intermediate suborders which connect the Pelargornithes with the 
Charadriiornithes, but which have an equal claim to be included in either, and must conse- 
quently be rejected from both. The Pygopodes appear to me to be highly specialized Fuli- 
cari, and I have been obliged to make use of the absence of some of their special characters 
to exclude them from that suborder. ‘The Tubinares may be highly specialized and advanced 
Gayie, and the Impennes are possibly highly specialized and retrograde Gavi, but the 
evidence in favour of these hypotheses is very weak.
