68 Brewster on a Collection of Arizona Birds. 
ble to var. unalascce. In fact it gives nearly the same measure- 
ments as the smallest extreme in the large series examined by 
Mr. Henshaw.* Mr. Stephens marks it as the first which he 
has seen in Arizona where, however, it was found sparingly by 
Mr. Henshaw in October, 1873. 
283, $ ad., Tucson, April 25. Length, 6.40; extent, 10. 10; wing, 3.26; 
tail, 2.61; culmen, .52. “Bill dark brown, yellowish at base of lower 
mandible ; legs pale brownish ; iris brown.” 
2. Turdus ustulatus Nutt. Russet-backed Thrush. — 
Under this heading I include with some hesitation, a Thrush killed 
May 17, in the Santa Rita Mountains. The specimen unfor- 
tunately was one of three or four which were accidentally 
destroyed while in the collector’s possession, but Mr. Stephens 
is positive that it was referable to the above variety. As he is 
perfectly familiar with ustulatus , having previously met with 
it in California, there can, I think, be little doubt of the cor- 
rectness of his 'determination. This record, if accepted, will 
make the first for Arizona. 
397, $ ad., Santa Rita Mountains, May 17. Length, 6.90 ; extent, 10.70; 
“Iris dark brown; bill black, brownish at base of lower mandible; legs 
very pale brown.” 
3. Turdus migratorius propinquus Ridgw. Western 
Robin. — Robins were met with only in or near the Chiricahua 
Mountains, where perhaps a dozen individuals were seen. The 
one mentioned below is typical of the slightly differentiated, but 
still apparently constant western race. 
75, $ ad., Morse’s Mill, March 20. Length, 10; extent, 16.40; wing, 
5.38; tail, 4.36. “Iris dark brown.” 
4. Oreoscoptes montanus {Towns.) Baird. Mountain 
Mockingbird. There is no mention of this species among the 
notes made during the late trip. 
6313 (author’s coll.), $ ad., San Pedro River, Dec. 25, 1880. 
Length, 8.90; extent, 12.40. 
5. Mimus polyglottus {Linn.) Boie. Mockingbird. — 
‘‘Generally distributed and common, but not as abundant as in 
Southern California” (Camp Lowell) . “Common in the val- 
leys ; they are found but a short distance up the foot-hills of the 
mountain ranges” (near Tombstone). 
181, $ ad., near Tombstone, April 8. Length, 9.80; extent, 13.10; 
wing, 4.30; tail, 5.03.
