OSTEOLOGY OF BIRDS 233 



EXPLANATION OF PLATES 



The material which is figured upon these plates is represented by 

 specimens which belong either to my private collections, now the 

 property of the New York State Museum, or to the collections of 

 the United States National Museum at Washington, to which in- 

 stitution my thanks are due for the loan of them for use in the 

 present connection. I am also greatly indebted to Mr F. A. Lucas, 

 formerly Curator of the Osteological Department there, for his 

 kindness in placing this material so promptly at my disposal. The 

 figures on all the plates are reproductions of photographs made by 

 the author direct from the specimens, and none of these figures have 

 heretofore been published. 



Although I examined complete skeletons of C r a x p a n a m e n - 

 sis, Arboriphila charltoni (Tropicoperdix JUyth. ?), 

 P h a s i a n u s t o r q u a t u s and Phasianus reevesi 

 and a number of others in the collections of the United States 

 National Museum, they are not figured in the present treatise, but 

 the characters they present have been taken into consideration as 

 well as those of other groups of the Gallinae.
