in the Arkansas Valley west of Lamar, November 30. Gaume's Ranch is 

 very near the eastern limit of its dispersion in Colorado, while Caddoa 

 represents the extreme northeastern limit of mesoleucus in the United 

 States. 



Calamospiza melanocorys. Lark Bunting. — A belated migrant was 

 noted a few miles east of Saguache, in the San Luis Valley, November 7, 

 1907. 



Progne subis. Purple Martin. — Unusually high records for the 

 martin are: White River Plateau (25 miles southeast of Meeker) between 

 8000 and 9000 feet — several seen the middle of August, 1905; and 

 Uncompahgre Butte, on the Uncompahgre Plateau — one noted at 9000 

 feet, July 16, 1907. 



Lanius borealis. Northern Shrike. — One seen from a Santa Fe 

 train at Earl, Las Animas County, November 25, 1907, and several a few 

 days later at Gaume's Ranch, in the northwest corner of Baca County. 

 These localities indicate a southward dispersion in winter nearly if not 

 quite to the southern line of the State. 



Lanivireo solitarius cassini. Cassin Vireo. — A specimen was collected 

 September 4, 1906, at Douglas Spring, in the cedar belt at the north base 

 of the Escalante Hills, western Routt County, and two more were heard 

 at the same locality on September 6. A large vireo, presumably cassini, 

 was also seen among the pinons at Coventry, Montrose County, in July, 

 1907. 



Dendroica gracise. Grace Warbler. — Tolerably common in the 

 yellow pine forests of Archuleta County, on the headwaters of the San 

 Juan River, at about 7000 feet, a specimen being taken at Pagosa Springs, 

 May 28, 1907. A very active warbler, almost continually in motion, 

 appearing in nervous haste to catch the small insects which infest the 

 terminal bunches of pine needles. 



Dendroica nigrescens. Black-throated Gray Warbler. — This war- 

 bler extends north in the cedar and pinon country of western Colorado to 

 the Escalante Hills, western Routt County, where several were seen at 

 Douglas Spring, September 4 to 8, 1906. In 1907 — Mesa Verde, Monte- 

 zuma County (7000 feet), common June 14; Sinbad Valley, southwestern 

 Mesa County, common in July; Coventry, a few during July and an im- 

 mature specimen collected July 25. 



Dendroica townsendi. Townsend Warbler. — A male shot August 24, 

 1906, on Snake River, 20 miles west of Baggs Crossing, was on its south- 

 ward migration with a large company of Pileolated and Yellow Warblers. 



Geothlypis trichas occidentalis. Western Yellow-throat. — One 

 was seen July 12, 1905, in a willow copse along Grand River, 5 miles east of 

 Sulphur Springs, Middle Park. The elevation, nearly 8000 feet, is excep- 

 tionally high for the Yellow-throat. 



Setophaga ruticilla. Redstart. — A few migrating individuals were 

 noted in a large company of Pileolated Warblers on the lower Snake River, 

 20 miles west of Baggs Crossing, August 25 to 27, 1906.
