114 THE CONDOR VoL. X October 3, is still in the midst of the moult, and ragged-looking birds were ob- served up to about the middle of the month. Young birds taken the end of October are, in every respect, absolutely indistinguishable from the adults. Aimophila cassini. Cassin Sparrow. Several were seen in some fields of tall grass near the mouth of Miller Canyon. It was almost impossible to secure speci- mens, from their habit of lying until almost trodden upon, and then darting off in zig-zag flight through the grass, to repeat the performance when foilowed up. An immature female shot on October 25 is in the midst of the moult, covered with pin feathers, and others seen during the first week in November were quite as ragged in appearance. Aimophila ruficeps scotti. Scott Rock Sparrow. Fairly abundant on the rocky hills of the Rincon Mountains. An adult male secured on September 25, and others seen at the same time, were in the midst of the moult. A few were seen in the Huachucas. Melospiza lincolni. Lincoln Sparrow. A single bird was seen in the t-Iuachu- cas on October 11. Pipilo maculatus montanus. Mountain Towhee. A. few were seen in the Rincons, while in the t-Iuachucas they were abundant from the summit almost, but not quite, to the base of the range. Immature birds taken the last week in Sep- tember and during October are not appreciably different from adults. Pipilo fuscus mesoleucus. Canyon Towhee. I have never in the spring or summer seen this species as abundant in the t-Iuachucas as it was throughout the foothill region this fall. Early in October all the birds seen were moulting, and very ragged in appearence, and specimens with pin feathers on'them were taken as late as October 22. 0reospiza chlorura. Green-tailed Towhee. This species was seen in abund- ance in the chaparral country between Benson and the Rincon Mountains, on Sep- tember 22, evidently migrating. It was also met with in the Rincons, and later a few were seen in the foothills of the t-Iuachucas, the last observed being on October 30. My earliest fall date for the species in the latter range is Septem- ber 1 (1902). Zamelodia melanocephala. Black-headed Grosbeak. A very few were seen in the Huachucas during the first two weeks in October, the last observed being a female secured October 16. My earliest date for tile arrival of the species in this 'region is April 20 (1902). Calamospiza melanocorys. Lark Bunting. Seen in abundance along the San Pedro River between Fairbanks and' Hereford on September 30. It is rather sin- gular that the species was not observed anywhere else. Piranga hepatica. Hepatic Tanager. A very few were seen at various times in the lower parts of the Huachucas, below 5500. feet, the last observed being on October 25. My earliest record for the arrival of this species in the t-Iuachucas in the spring is April 11 (1902). An adult male taken October 1 had nearly com- pleted the moult. Piranga rubra cooperi. Cooper Tanager. An immature female taken in the Rincon Mountains on September 23, 1907, was the only one of the species observed. Tachycineta thalassina lepida. Northern Violet-green Swallow. Seen at various times during the whole of our stay in the mountains. Ampelis cedrorum. Cedar Waxwing. Several small flocks were seen in the Huachucas during the first week in October. In my experience this. is anything but a common species in southern Arizona. Phainopepla nitens. Phainopepla. A single bird, an adult male, seen at the
