A.—Left foot of a nestling Casuarius casuarius sclateri, to show the arrangement of the scutes of the podotheca. 
B.—Left foot, anterior aspect, of Casuarius lorie, for comparison with A, to show the large hexagonal 
plates clothing the proximal portion of the tarso-metatarsus. 
C.—Left foot of a newly hatched Dromeus nove-hollandie, to show the arrangement of the scutes of the 
podotheca, and the curious continuation of the pattern of coloration of the body down to the toes. 
D.—Left foot of a ripe embryo of Rhea americana, to show the arrangement of the scutes. Note the presence 
of feathers (f) on the tarso-metatarsus—temporary in this species, permanent in R. darwini. 
E.—Left foot of an embryo Apterya australis mantelli, to show the form of the scutes of the podotheca.
