599. Cyanospiza amoena (Say.). 

 Lazuli Bunting. 

 Probably a summer resident, but tbere are no breeding 

 records ; not common. During migration these birds appear 

 annually ; but never in great numbers. Coues refers to speci- 

 mens that have been taken at Laramie peak, Yellowstone river 

 and Wind river ; Allen reports them from Cheyenne ; Jesurun 

 finds them annually at Douglas ; Bond reports the captu; e of 

 a few at Cheyenne. West has sent in one skin taken at Buffalo. 



605. Calamospiza melanocorys Stejn. 

 Lark Bunting. 

 Summer resident and abundant on the east side of the 

 Big Horn and Laramie mountains up to 6,500 feet ; and a few 

 breeding as high as 7,300 feet. To the westward of these 

 ranges they decrease in abundance very rapidly and in western 

 Wyoming are seldom seen. Between Fort Laramie and Raw- 

 hide Buttes there are places where there are a dozen or more 

 pairs breeding on each section. The following are the import- 

 ant records: Wood, Pole creek, 1856; Stevenson, Wyoming, 

 1870; Holden, Wyoming, 1872; Coues, Big Horn mountains 

 and Bitter Cottonwood creek; Williston, common. Lake Como; 

 Jesurun, common at Douglas ; Cary, common south of the B. 

 M. R. R. south of Newcastle; The National Museum reports 

 three specimens taken at Laramie and Cheyenne. There are 

 two specimens taken at Laramie in the University collection. 



607. Piranga ludoviciana (Wils.). 

 Louisiana Tanager. 

 Summer resident and rather common in regions below 

 7,500 feet. Much has been said about the vertical range of 

 this species in the Rocky mountains. In Wyoming I have 

 never found it breeding at 8,000 feet, nor have I ever seen it 

 above that elevation. During migration they arrive on the 

 Laramie plains about the 15th of May, remain a week or so 

 and disappear. From an elevation of 6,000 feet, downward,
