EXPLORATIONS AND SURVEYS WEST OF ]OOTH MERIDIAN. 



Progne suUs, (L.) Purple Martin. 



Seen in the vicinity of Salt Lake City and at Camp Douglass. In 

 the middle of July the young were almost able to take wing. Also 

 seen in mountains of Middle Utah.

Vireo solitarius, (Wils.), var. plumbeus, Cs. Western Solitary Vireo. 



A single specimen was taken in August near Strawberry Valley. 

 Seen nowhere else in Utah.
