Incisurae laterales of sternum (character 48): A, sternum of Aburria pipile (Galliformes, Cracidae) in ventral view; B, sternum of Cairina moschata (Anseriformes, Anatidae) in ventral views; incisura capitis of proximal humerus enclosed from crus dorsale fossa by a distinct ridge (character 61): C, left humerus of Aburria pipile (Galliformes, Cracidae) in caudal view; D, left humerus of Chauna chavaria (Anseriformes, Anhimidae) in caudal view; trochlea metatarsal III distinctly asymmetric (character 83): E, right tarsometatarsus of Lagopus mutus (Galliformes, Tetraonidae) in dorsal view; F, right tarsometatarsus of Chauna torquata (Anseriformes, Anhimidae) in dorsal view.
