Mazatlan, while two others (both males, but one of theui iimiiature) 

 from Auhuitlan, in the State of Oaxaca, are very different in being 

 clear Indian-yellow where the others are deep cadmium orange. The 

 black throat-stripe also appears to be narrower. The white on the 

 wings, however, is exactly as in the Chietla, Tepic, and Mazatlan speci- 

 mens, so it is therefore probable, or at least possible, that the differ- 

 ences noted may be due to difference of age. — R. R.]

[The adult male of this species possesses a character which appears 

 to have been overlooked by writers, in the possession of a very well- 

 developed ruff, the feathers of the neck, especially on the lateral por- 

 tions, being very much longer than those of the anterior portion of the 

 body. This ruff, in the specimens belonging to the collection of the 

 Commission, mounted immediately after shooting, strongly suggests 

 that of Pavoncella pugnax, but is not, of course, so conspicuous. — K. K.]
