central Texas; south to southern Mexico and Guatemala. In 

 migration it occurs east to Iowa. Accidental in Pennsylvania 

 and Massachusetts. 



Remarks. — The best character separating this new race 

 from Dendroica auduboni audiiboni is that of size, although this 

 is less marked in the female. There is considerable individual 

 variation in the amount of black on the lower parts, but this 

 is nearly always of greater extent than in Dendroica auduboni 

 auduboni. Birds from Arizona and Montana are of the same 

 size, and of practically the same coloration. Individuals from 

 Nevada and Idaho are intermediate between Dendroica auduboni 

 memorabilis and Dendroica auduboni auduboni, though they are 

 nearer the present form. The same remarks apply also to 

 breeding birds from the mountains in southeastern California 

 near the State border, as, for instance. Mount Whitney. All 

 the breeding birds from the mountains of Arizona, except 

 those from the Huachuca Mountains, belong to the present 

 race, but those from the southern part of the State verge a 

 little toward Dendroica auduboni nigrifrons. Comparative 

 wing measurements of adult males from different localities are 

 as follows: Arizona and New Mexico, 80.3 mm.; Wyoming 

 and Montana, 79.2 mm.; Idaho, 78.6 mm.
