SUBSP. CHAR. — Dift'ering from true D. bryanti in'having the head rich chestnut in- 

 stead of rufous. Adult $ (type, No. 89940, U. S. Nat. Mus., La Paz, Lower Califor- 

 nia, Dec. 16, 1882 ; L. Belding) : Head rich chestnut, lighter or more rufous on the 

 throat. Upper parts olive-green, the wings dusky, with broad greenish yellow edg- 

 ings ; outer webs of rectrices dusky, edged with yellowish olive-green, the inner webs 

 chiefly primrose-yellow. Lower parts bright gamboge-yellow, the jugulum and breast 

 with a few very indistinct and mostly concealed streaks of chestnut-rufous. Bill 

 dusky. Feet, dark horn-color. Wing, 2.70 ; tail, 2.20 ; culmen, .58 ; bill from nos- 

 tril, .35; tarsus, .80; middle toe, .49.

 Above grayish olive-green ; wings grayish dusky, the feathers edged with olive-gray- 

 ish ; rectrices dusky, outer webs edged with olive-green, the inner with primrose- 

 yellow. Lower parts dull pale olive-yellowish. Wing,2.50 ; tail, 2.10 ; culmen, .55 ; 

 bill from nostril, .30; tarsus, .80; middle toe, .45. 



^a&.— Western Mexico (vicinity of Mazatlan) and vicinity of La Paz, Lower Cali- 

 fornia. 



The male selected as the type is the one having the head lightest in color of the 

 three Lower Californiau examples before me. The other two differ as follows : 



No. 86260, U. S. Nat. Mus., La Paz, January 6, 1882; L. Belding: Head slightly 

 darker chestnut, especially the pileum ; breast with the streaks rather more distinct 

 (but still very faint), and sides similarly streaked. Wing, 2.60 ; tail, 2.25. 



No. 89938, La Paz, December 19, 1h82 ; L. Belding: Head still darker chestnut than 

 in No. 86260. Streaks on lower parts about the same. Wing, 2.60 ; tail, 2.10. 



Young males, obtained in December, are similar to the female, as described, but 

 brighter in color and with the head more or less touched or mixed with chestnut. 



Two adult males from Mazatlan are essentially identical with the La Paz specimens. 

 They measure as follows : 



No. 582.52, Mazatlan; Col. A. J. Grayson: Wing, 2.50; tail, 2.10. 



No. 35017, Mazatlan, August ; Col. A. J. Grayson : Wing (molting) ; tail (molting). 

 " Bill black above, margined with paler; under mandible lead-color."
