 dent up to 4500 feet ( Scott, t888, p. 34) The northernmost record I have seen 

 from central Arizona is from Fort \'erde ( Coale, 1894, p. 218). I know of no 

 breeding record of a yellow warbler from any point in Arizona north of the 

 Mogollon Divide ; what form it is that migrates through this region T do not 

 know {Dcndroica aestira Merriam, 1890, p. 08, San Francisco Mountain, etc., 

 August and September; Fisher, 1893b, p. T13, confluence of Beaverdam and Vir- 

 gin rivers. May; etc.).

 from the Huachuca Mountains, in the extreme southeastern portion of the state

 Zool.). These are distinctly D. a. hrezvsteri, as distinguished from D. a. aestiva 

 of the eastern United States.
