of rufous, becoming browner on the sides of the neck till it gradually 

 assumes the color of the hind-neck ; lower part of breast and abdo- 

 men spotted with ferruginous-white and brown ; flanks brown, spotted 

 with white, narrowly margined with pale-rufous ; lower part of abdo- 

 men pale ferruginous-white, barred with ferruginous-brown ; crissum 

 the same, but with the bars less distinct ; tibiae pale rufous, beautifully 

 barred with a deeper shade of the same color. 



Buteo calurus <5, No. 5,481. Above, purplish-brown, lightest on 

 the head, and with the margins of most of the feathers as if faded, 

 and the shafts black ; the scapulars and tertiaries more or less marked 

 with grayish white ; ends of primaries dark purplish-brown, the rest 

 banded on both webs, at first very obscurely, but gradually more dis- 

 tinctly, with two shades of brown ; tail bright rufous, tipped with white, 

 with about eight irregular black bands, all, excepting the last, very 

 narrow. Below, with the throat fuliginous, breast and abdomen 

 brown, much darker on the flanks and centre of abdomen, where 

 there is a distinct purplish gloss. Tibia? and lower part of abdomen 

 dull brown, with the feathers margined with pale dull rufous. Cris- 

 sum pale dull rufous, barred with dusky. A specimen from Fort 

 Tejon difiers from the above in having the feathers of head and hind- 

 neck pretty broadly margined with rufous ; upper tail coverts bright 

 rufous, barred with dusky. Below, throat blackish-brown, hardly 

 showing any white ; breast and abdomen dull rufous, with the brown 

 of the throat, as it were, gradually shaded in, the shafts only of the 

 lower feathers being dark, then with a narrow stripe, growing broader 

 towards the throat, so that on the upper part of the breast there is 

 only a narrow margin of rufous ; centre of abdomen and flanks of 

 the same color as the throat, the margins of the feathers pale rufous 

 or hoary ; tibiae and lower part of abdomen pale rufous, barred with 

 dusky, the ends of the feathers on the abdomen of a dirty white ; 

 crissum pale rufous, barred with darker towards the tail, the bars 

 gradually becoming brown next the abdomen. 



No. 16,026 differs from the last in having the rufous edging of the 

 feathers continued to the interscapular region, — in the breast being of 

 a much brighter ferruginous, — in the dark spots, which are tear-shaped 

 instead of acuminated as in the last, being continued to the upper 

 part of abdomen, — in the centre of abdomen being of a very dark 

 purplish-brown, the feathers margined with rufous, — and in the tibiae 

 and crissum being much less distinctly but more broadly barred with 

 brown, the two colors being much darker. 



No. 10,571 from Tejon, has the feathers of the throat narrowly 

 edged with rusty, the ferruginous of the breast and lower parts re- 

 placed by pale rufous, the black band across the abdomen consisting 

 of a few elongated blackish-brown spots. Tibias and crissum without 

 bars, upper parts similar to the last. A specimen from Fort Crook,
