Jan., 1910 SOME CENTRAL COLORADO BIRD NOTES 39 way between Beulah and Pueblo, and rather frequently between Eden and Buttes stations. Duraetella car01inensis. Catbird. Several seen at Glendale, and Durand took one in Hardscrabble Cation. Salpinctes 0bs01etus. Rock Wren. Seen at favorable places between Colorado Springs' and Texas Creek; between Meats and Poncha Pass; near the roadside, in northern .I-Itlerfano County: at Querida, where family parties were seen; about ten miles west of Pueblo, and between Eden and Pition stations. Tr0g10dytes aed0n parkmani. Western House Wren. Seen at different places between Colorado Springs and Howard; at Durkee Ranch; Mosca Creek; Muddy Creek; in Hardscrabble Cation one was caught in a mouse trap set under the over- hanging creek bank; also seen near Buttes. Cist0th0rus stellaris. Short-billed Marsh Wren. Cary took one at Medano Ranch, October 23, 1907 (?lu}, xxvI, p. 182, April, 1909). We made a careful search for the bird, especially at the small lake where we were told he obtained his specimen, but no birds were found, and no nests were to be found about the cat-tails and rushes where they would have built if they had been there, so I have come to the same conclusion as in the case of the Swamp Sparrow, that Cary's bird was a straggling migrant. Telmat0dytes palustris plesius. Interior Tule Wren. Henshaw, in his report, records three specimens from the San Luis Lakes, taken in May and June, 1873. While I did not know of this when at the lakes, the search for the Short-billed Wren should have revealed this species if it had been there. Sitta car01inensis neis0ni. Rocky Mountain Nuthatch. Seen at Howard, and at Mosca Creek. Also taken at Querida, February 6, 1909. Penthestes atricapillus septentri0nalis. Long-tailed Chickadee. Seen at Her- ard's Ranch, Madenos Creek. Penthestes gainbell. Mountain Chickadee. Taken at Ho?rard and Querida; also at latter place, February, 1909. Psaltriparus plurabeus. Lead-colored Bush-tit. Taken near Parkdale; seen at Texas Creek, and at Howard. Myadestes t0wnsendi. Townsend's Solitaire. One seen on a high ridge near the head of Madenos Creek. Planesticus raigrat0rius pr0pinquus. Western Robin. Seen constantly from Colorado Springs to Villa Grove; after that none were seen until we got to the Dur- kee Ranch, and from there on seen at every locality until we reached Colorado Springs. Sialia raexicana bairdi. Chestnut-backed Bluebird. Seen about a mile west of Texas Creek, and Durand saw four or five near our Madenos Creek camp. Sialla curruc0ides. Mountain Bluebird. Seen almost everywhere from Colo- rado SpYings to Beulah. After the middle of July many young birds were seen. FOR THE BETTER DETERMINATION OF A.(?ELAIU?S' TRICOLOR By JOHN W. MAILLIARD wrr?

ITH only a limited reference library available, it is perhaps unwise to un- dertake the betterment of the determination of a species; and yet our own douts, coupled with those exprest by many of our ornithological friends,
