414 Oberholser, Races of Hedymeles melanocephalus. [j^y 



satisfactory. The absence of a tawny postocular stripe in Hedy- 

 meles melanocephalus papago is the best color character. The 

 tendency of birds from the Rocky Mountains to have the crown 

 solidly black instead of with a tawny median stripe is very incon- 

 stant, and, besides, is shared by Mexican birds, and is thus of no 

 diagnostic value. The difference in the depth of the color on the 

 throat, breast, sides, rump, and crissum, and the width of the white 

 tips on the median coverts, mentioned by Dr. Grinnell in the 

 original description of his Zamelodia melanocephalus microrhyncha, 1 

 prove by examination of our large series to be merely individual 

 variations. 



Breeding birds from Jaumave, Tamaulipas; Sierra Guadalupe, 

 Coahuila; and Cerro de la Silla, Nuevo Leon, are practically 

 typical of the present subspecies; and a single female from Atlfxco, 

 Puebla, without date, but which, of course, represents a winter 

 record, is also typical. Specimens from Pyramid Lake, the Moni- 

 tor Mountains, Toyabe Mountains, and Mountain City, all in 

 Nevada, are a little small but much nearer Hedymeles melano- 

 cephalus papago than to the typical race. The same remarks will 

 apply to birds from localities in southeastern Idaho. 



An adult male (No. 49757, U. S. Nat. Mus.) from Camp Grant, 

 Arizona, taken, May 14, 1S67, by Dr. Edward Palmer, exhibits 

 a peculiar individual plumage variation in the color of the upper 

 throat, which is bright yellow. 



As explained under Hedymeles melanocephalus melanocephalus, 

 all the names applied to the species pertain to that race, since we 

 now refer the Mexican representatives to the same subspecies as 

 those from California. 



Of this race 141 specimens have been examined, from the sub- 

 joined localities:

 1893; Sept. 5, 1893; July 12, 1888); Grand Canyon of the Colo- 

 rado (May 14, 1884); Fort Whipple (July 21, 1865; Aug. 10, 1864);
