148 BULLETIN OF THE 



CINCLID^I. 



6. Cinclus mexicanus. Seen on the Fontaiue-qui-bouit, at Colorado 

 City, August 1st. 



SAXICOLIDJE. 



7. Sialia mexicana. One pair observed in the foot-hills west of Denver. 

 There is also a specimen in the Museum, collected near Denver. It is 

 from the late Mr. Cassin's collection, and bears the following label : " Sialia 

 mexicana, Clear Creek, Rocky Mts., K. T., July, 1859. W. S. Wood, Jr." 



8. Sialia arctica. Many seen, and three shot, a few miles north of 

 Colorado City. 



SITTID.S2. 



9. Sitta carolinensis. A single specimen was seen about twenty miles 

 north of Colorado City, on the Monument. 



TROGLODYTIDJE. 



10. Salpinctes obsoletus. Obtained in the foot-hills southwest of 

 Denver, on Bear Creek. 



11. Catherpes mexicanus. Common in the Garden of the Gods, 

 near Colorado City. Seen only on the bare rocks. The vertical sandstone 

 cliffs of the Garden of the Gods seemed to afford them a favorite haunt, over 

 which they flitted to the highest points of the naked cliffs. Their shrill, 

 ringing notes reverberated among the cliffs with almost incredible loudness, 

 it seeming almost impossible that so small a bird should be able to produce 

 such penetrating and startling echoes. 



12. Troglodytes aedon. Common everywhere. 



A bird supposed to be Chamcea fasciuta was observed in the foot-hills near 



Colorado City. Although no specimens were obtained, it was seyeral times 



seen, and watched at a distance of only a few yards, and I feel confident it 



was that species, though previously known only from localities as distant as 



Lower California. 



SYLVICOLIDJE. 



13. Icteria virens. Common near Colorado City, and also observed 

 near Denver. 



14. Dendrceca Auduboni. Common along the streams at the foot of 

 the mountains from Colorado City to Denver. Properly a bird of the moun- 

 tain fauna. 



15. Dendrceca aestiva. Occasional from Colorado City to Denver. 



16. Setophaga ruticilla. Common in the foot-hills west of Denver, 

 the first week in July, and also seen at Colorado City. 



HIRUNDINIDJE. 



17. Hirundo horreorum. Generally dispersed, but not numerous. 



18. Hirundo lunifrons. Abundant at Denver, common at Colorado 

 City, and frequently seen between these points.
