66 BONELLl's EAGLE. 



the head, nape, throat, belly, thighs, and under tail 

 coverts a rich cinnamon brown, streaked on the under 

 parts with long narrow longitudinal black bands on the 

 shafts of each feather. The head and nape are marked 

 with dark longitudinal stripes. Back and tail dark 

 brown; quill feathers darker, slightly marked with 

 white. 



Three other specimens (females) have a plumage in- 

 termediate between the two, doubtless in consequence 

 of age, as it varies much every year. According to 

 Marmora and Temminck the beak in the adult is 

 horn-colour; cere and feet livid yellow; iris brown. 



Birds of the year have the iris brownish yellow. 

 Birds of the third year have the iris a clear yellow, 

 and the tail without the dark border at its extremity, 

 and marked with nine or ten transverse bands. There 

 are seven large scales on the last joint of the median 

 toe in the adult, and four on that of the external and 

 internal.
