Long s Exp. to the Rocky Mts. vol II, p. 4. 

 Salpinctes obsoletus, BAIRD, Gen. Rep. IX, 357. 



I have met with this bird not only throughout the whole extent of California, but also in 

 New Mexico and Texas, and while encamped in the Tejon valley have often, in the course of 

 the day, obtained from five to six specimens. It frequents the rocky portions of the country, 

 passing in the crevices and under the boulders which lie profusely scattered over the mountains. 

 It lives upon spiders, worms, and small insects, and while in pursuit of them it utters, at 

 intervals, a loud, quick note, of a peculiarly thrilling character. 



TROGLODYTES MEXICANUS, Swains .Mexican Wren. 



Troglodytes mexicanus, Sw. Zool. Illus. 2d series, vol. I, pi. 11. 

 Catherpes mexicanus, BAIRD, Gen. Rep. IX, 356. 



On a previous visit to California, I procured this species on the Calaveras and Cosumnes 

 rivers. Its habits and resorts are the same as the Trog. obsoletus. 



TROGLODYTES BEWICKIC, A ud .Bewick s Wren. 



Troglodytes bewiikii, AUD. B. of A. Oct. vol. II, p. 120, pi. 118. IB. Fol. pi. 18. NUTT. Orn. vol. I, p. 434. 

 Thryothorus bewickii, BAIRD, Gen. Rep. IX, 363. 



Abundant. Near Fort Clark, Texas, I found a nest of this species constructed in an old 

 Comanche Indian shield. The target, formed of two thicknesses of hide, had been hung on a 

 bush as a mark to fire at ; from exposure to the weather, the two sides, having separated, 

 formed a pocket, in which this bird had domiciliated itself. It is like the rest of the genus, 

 very querulous in its notes, repeating, when disturbed, its alarm cries with great vehemence.
