206. Dendroica townsendi Townsend's Warbler. 

 Straggler from the far west. C. D. Wood, a Phila- 

 delphia taxidermist, killed an adult male near 

 Coatesville, in an apple orchard; May 12, 1868. 

 Sole Eastern record. This specimen was sold for 

 $40 to Dr. Turnbull, and after his death purchased 

 by B. A. Hoopes, who subsequently disposed of it to 

 John Krider (Warren, Bds. Pa., 246). It later 

 came into the possession of Prof. E. D. Cope, and is 

 now in the Academy of Natural Sciences, Philadel- 

 phia (Stone, Osprey, iii, 98).

 mon transient. Barnard states that it arrives May

 Berwyn, May 6, 1905, and Kennett Square, May 

 16, 1914, and Apr. 17, 1915 (Thomas MS.).

 1889; Sept. 17 to Oct. 18, 1890.
