 be of the species to which I refer it. I have nol met with any 

 description of B. albonotatus in its immature plumage, it re- 

 sembles my specimen of the adult in its general proportions,

 front part of the tarsus feathered below the knee as in /'. al~ 

 bonotatus. The feathers above are dark brown, showing much 

 white on their edges, particularly on the head and hind n< 

 the upper tail coverts are white with wavy brown bars; tail 

 bluish ash, crossed with narrow dusky bars; under pluini 

 white, with large oval brown spots on the breasl and a few 

 sagittate ones on the sides; under wing coverte pale Balmon 

 color, the under plumage more or less tinged with tin
