678 GEOLOGICAL SURVEY OF THE TERRITORIES. 



Family 15. — Tanagrid^e, the Tanageks. 

 Pyranga ludoviciaua, Bonap., (Louisiana tauager :) 



Jlah. — From the Black HilLs to the Pacific; south into Mexico. 



I found a few of these beautiful birds iu the bushes that border Crow 

 Creek, uear Cheyenne, and succeeded in obtaining one good specimen, 

 No. 1, (01GG2.) I also saw several in the scrub-oak bushes at the foot 

 and on the sides of the Wahsatch Eange, uear Ogden. 



At Teton Caiiou, however, these birds are quite abundant, and here I 

 obtained eight specimens. They were generally seen on the tops of the 

 inue trees, where the bright colors of their i)lumage contrasted beauti- 

 fully with the dark green foliage of the piues. They are secluded iu 

 their habits, preferiug their own society to that of other birds, and 

 seldom approaching the habitations of man, 



Near Ogden they were shy and' suspicious, and it was difficult to get 

 within gunshot of them, while, on the contrary, at Teton CaQon, they 

 eyed us with curiosity only, not' suspicion, for they would often follow 

 us for some distance, lighting near b^', and never trying to keep out of 

 sight. 



Family IG. — Feingillid.t^, the Sparrows. 

 (Sub-family Coccothrcmstinw.) 

 Carpodacus cassinii, Baird, (Cassiu's purple finch :) 



Sab. — Rocky Mountains and valley of the Colorado. 



These birds, the largest of the American purple finches, are quite 

 rare. We met with them but twi(^,, once on the Yellowstone, and once 

 uear Snake River, Wyoming Territory.
