nab.— Brazil. (Type 50994(J', and 50995 9. Brazil, Sr. Don Fred. Albu- 

 querque. 



This species, although belonging to the sestiva style, is nevertheless a well 

 marked one, and one for the identification of which a comparison with the 

 others is scarcely necessary. In uniformity of colors, as well as in general 

 style of color, it mueh resembles xstiva ; the superciliary stripe, however, at 

 once distinguishes it from this. The red of this species is also very different 

 from that of any other, being purer and richer, approaching in fineness and 

 tint that of Pyranga rubra. 



Pyranga hepatica, Swainson. 



Pyranga hepatica, Swainson, Phil. Mag. I, 1827, 438— Baird, B. N. A. 1858, 

 302. — Pyranga dentata, Licht. — P. azarie, Woodhouse, Sitgreave's Report. 



Sp. ch. " Length 8-00," wing 4-12, tail 3'36, culmen -68, tarsus -84. Second 

 quill longest, first intermediate between fourth and fifth. Bill somewhat 



shorter than that of csstiva, but 

 broader and higher at the base, be- 

 coming compressed toward the end ; 

 a distinct prominent tooth on com- 

 issure. Color plumbeous-black, 

 paler, or more bluish plumbeous on 

 lower mandible. Head above brown- 

 ish red, purer anteriorly ; rest of up- 

 per parts and sides brownish ashy, tinged with reddish ; edges of primaries, 

 upper tail-coverts and tail, more reddish. Beneath, medially, fine light scar- 

 let, most intense on the throat, growing gradually paler posteriorly. Lores 

 and orbital region grayish white ; eyelids pale-red ; ear-coverts ashy red. 



Female. — Above ashy greenish olivaceous, brightest on forehead ; edges of 

 wing feathers, upper tail-coverts and tail, more ashy on the back; beueath 

 nearly uniform olivaceous yellow, purer medially ; lores ashy ; a superciliary 

 stripe of olivaceous yellow. Young male similar to the female, but forehead 

 and crown olivaceous-orange, brightest anteriorly ; superciliary stripe bright 

 orange, whole throat, abdomen and breast medially rich yellow, most intense 

 and tinged with orange-chrome on throat. 



Hub. — Mountain regions of Mexico and Southern Rocky Mountains of U.S. 

 This species differs from all the others in the great restriction of the red ; 

 this being confined to the head above, and median lower surface, the lateral 

 and upper parts being quite different reddish-ashy. The shade of red is 

 also peculiar, this being very fine and light, of a red-lead cast, and most in- 

 tense anteriorly. 



Pyranga azar^, D'Orb. 



Pyranga azarse, D'Orb., Voyage, 264. 



Sp. ch. Wing 3-60, tail 3-32, culmen -64, tarsus 80. Bill smaller than in 



hepatica, and narrower ; commissural tooth 



obsolete or, in fact, not observable ; color 



^^ blackish plumbeous, as in hepatica. Sec- 



^^ — - — ^!^^^^V^ '^C!.,,^^ ^20625 Qjj(j quill longest: first scarcely shorter 



than third. 



General tint below dull light Vermil- 

 lion, less clear than in hepatica and less 

 restricted, the sides being scarcely obscured by grayish ; the shade is also 

 continuous, the crissum being as intense as the throat. Above dull purplish 

 brown, more reddish on edges of primaries and tail feathers ; head above 

 strongly tinged with red ; lores and eyelids well defined dull white ; ear cov- 

 erts dull red. (Plumage of female unknown.) 



This species, of which there is but one specimen in the collection, is most 

 nearly related to hepatica ; it differs from this, however, in smaller bill, with-
