LIST OF DIURNAL BIRDS OF PREY. 



1 Mr. Sharpe uses for this species the specific name " semitorquaius ;" Temminck 

 figures it as " Falco brachi/pterus." 



^ This specimen is one of the two types of the species, the other being in the collection 

 of Messrs. Salvin and Godman. 



^ Mr. Ridgway here gives the only description with which I am acquainted of the 

 immature plumage of 31. mirandoUei. I may mention that both the specimens 

 contained in the Norwich Museum were obtained in Guiana ; these and the few others 

 which I have seen are in adult plumage, and the immature dress is only known to me 

 from Mr. Ridgway's description.
