tints of rubra, having them duller above, and slightly tinged with reddish beneath. The bill 

 is much larger than in rubra, nearly equalling the head ; quite so in some specimens, varying 

 considerably in size, as it does. Texas specimens generally appear to have larger bills than 

 those farther east. 



The young male is like the female. Immature males, however, exhibit every gradation 

 between the perfect colors of both sexes.

I have at hand no full plumaged male of this bird, and have been obliged to borrow the 

 description from Sclater, as cited above. The species is considerably larger than P. aestiva, 

 with which it agrees somewhat in characters. Tlie bill, however, is proportionally smaller, 

 with more of a tooth on the commissure. The color, too, is bluish black, instead of light horn 

 color, with yellowish margins. The sides are tinged with ashy instead of being like the belly. 

 The red is of a different shade, duller above, and the forehead conspicuously brighter than the 

 back, instead of a meie shade lighter. 



Accordin*' to Sclater the F. saira, (P. amrae, Auct.,) to which this bird was referred by Dr. 

 Woodhouse, differs in being smaller, the bill bluer, the feet black, not brown, the red colors 

 different. The female is also said to have a yellowish superciliary stripe.
