I saw Imt once, at Fort Mojave, in April, a bird wliicli I thought might 

 be of tliis species, but could not shoot it on account of tlie dense thicket it 

 fretpteuted. Dr. Keniierly found them along Williams's Fork, among high 

 rocks, darting from one to another, and creeping al)Out their crevices very 

 rapidly, so that he could scarcely kill one, keeping up at the time a strange 

 ciy. 



Dr. Heermann found them along the Calaveras and Cosuranes Pavers iu 

 fall and spring, very active, with a loud, sprightly song, heard at a consider- 

 able distance, and often repeated. They were searching for insects among 

 the large boulders along tlie river. He remarks that their hal)its and re- 

 sorts are the same as those of the Salpindcs ohsoldus. 



I have not met with this bird myself iu the more northern country, or 

 near the coast, but obtained a specimen collected by Mr. Lorcjuin, some- 

 where in the San Joaipiin Valley.
