skins. Drexel reports one from Fort Bridger, and there is 

 one skin in the University collection that was taken by West 

 at Buffalo and another that was taken at Sundance. Coues re- 

 ports this variety from Powder river, The Tower, and five 

 specimens in general from the state. 



592-1. Oreospiza chlorura (Aud.). 

 Green-tailed Townee. 

 Summer resident and abundant over the state. They pre- 

 fer a hilly or mountainous country, where there is an abund- 

 ance of brush and scattering trees. I have found them breed- 

 ing in the Laramie, Medicine Bow, Ferris, Rattlesnake, Big 

 Horn, Bear Lodge and Wind River mountains at elevations 

 varying from 6,000 to 8,000 feet. Nearly all observers have re- 

 ported them and the records are too voluminous to publish. 



596. Zamelodia melanocephala (Swains.). 

 Black-headed Grosbeak. 

 Summer resident in Big Horn, Johnson and Crook coun- 

 ties and probably further southward ; not common. There are 



no breeding records from south- 

 ern and western Wyoming. Coues 

 records this species from Sinking 

 creek and the Big Horn river ; 

 Grinnell from Yellowstone park ; 

 Jesurun from Douglas ; Bond 

 from Cheyenne and Silver 

 Crown. The following records 

 have been obtained from the Na- 

 tional Museum : Nos. 88077 an d 

 88078, taken at Fort Laramie ; 

 No. 68889, taken at Laramie ; 

 Nos. 1 1 241, 1 1 246 and 11248, ta- 

 ken at Fort Bridger. West has 

 sent one skin from Buffalo. 

 There are two Wyoming skins in the University collection-
