Sp. Chak. Adult. Above rich dark vandyke-brown, darker anteriorly, less intense and 

 more grayish on tail. A narrow streak of brownish-black originating over the middle of 

 eye, and extending backward above the upper edge of the ear-coverts, where it forms 

 an elbow passing downward in a broad stripe over the ends of the ear-coverts; confluent 

 with this, at about the middle of the vertical stripe, is another of similar tint, which 

 passes more broadly down the side of the nape ; between the last stripes (those of 

 opposite sides) is auotlier or medial one of less pure black, extending from the occiput 

 down the nape. Every feather of the forehead, crown, and occiput with a central ovate 

 dot of white ; those anterior more circular, on the occiput less numerous and more linear. 

 Between the lateral and posterior nuchal stripes the white prevails, the brown forming 

 irregular terminal and transverse or medial spots ; these grow more linear toward the 

 back. Interscapulars plain ; posterior scapulars variegated with partially concealed large 

 transverse spots of white, the lower feathers with nearly the whole outer webs white, 

 their confluence causing a conspicuous elongated patch above the wing. Rump with 

 sparse, irregular, but generally transverse, spots of white ; upper tail-coverts with broader, 

 more regular bars of the same, these about eqvial to the Ijrown in width. Lower feathers 

 of the middle and secondary wing-coverts each with an ovoid spot of white on the outer 

 web ; .secondaries crossed l)y about three transverse series of longitudinally ovoid white 

 spots (situated on the edge of the feather), and very narrowly tipped with the same ; 

 primary coverts with one or two less continuous transverse series of spots, these found
