Order VII. TROGONES. 



The Trogons differ from all other birds in the structure of the 

 feet. The first and second digits are turned backwards, and are 

 supplied by the flexor lonyus hallucis, and the third and fourth 

 digits are directed forward and connected with the flexor perforans 

 digitorum. The two flexor tendons are united by a vinculutn 

 (fig. 58).

 pterygoid processes are present. Sternum with four notches on 

 the posterior border ; manubriurn long, slightly forked ; coracoids 

 in contact. Oil-gland nude. Cseca present. Spinal feather-tract

 contour-feathers large. No median wing-coverts. Ambiens 

 muscle wanting. Plumage of the young nearly resembling that of 

 .the female.
