This may be considered as a rare bird in tbje tract of country through 

 which we passed, as I saw but one specimen, which I shot — No. 24:0, 



(G2297.) 



Family 7.— TEOGLODYTiDiE, the Weens. 

 (Sub-familj- Campylorhynchinc€.) 

 Salpinctes obsoletus, Cab., (rock-wren.) 



Hah. — High central plains through the Rocky Mountains to the Coast 

 and Cascade Ranges, (but not on the Pacitic coast %) 



This bird is very properly called the " rock- wren," for high up the 

 mountain sides and among the rocks it lives, lays its eggs, and teaches 

 its young the use of their tiny wings. They are noisy creatures, and seem 

 to take great pleasure in darting from rock to rock, keeping generally 

 out of sight. 



I shot the first of this species that I saw on one of the rocky spurs of 

 the Wahsatch Range, near Ogden — No. 04, (G1654.) They were quite 

 abundant on the rocky hills near the Hot Sulphur Springs, ten miles 



north of Ogden 



(Sub-family Troglodi/tince.) 



Cistothorus palustris, Cab., (long- billed marsh-wren.) 



Hah. — North America from Atlantic to Pacific, north to Greenland. 



Fort Plall is the only place where I found the long-billed marsh-wren. 

 I saw several of them there, but succeeded onl}' in obtaining one speci- 

 men — No. 302, (02327.) This bird, though not gay in colors, is a sweet 



songster, 



Troglodytes parhmanni, Aud., (Parkman's wren:) 



Hah. — Western America, from the high central plains and Upper Mis- 

 souri to the Pacific. 



This little bird, very similar to our house-wren, (T. axlon,) was quite 

 common at North or Henry's Fork of Snake River, Middle Fork, Teton 

 Canon, and Fort Ellis. I found its nest, on the 20th of July, at Middle
