82 Brewster on a Collection of Ai'izo?ia Birds. 
2 6. Campylorhynchus brunneicapillus ( Lafr .) Gray. 
Cactus Wren. — I notice little of special interest among the 
notes accompanying the eight skins which Mr. Stephens col- 
lected. He found the bird abundant in all suitable localities, and 
took several nests and sets of eggs. The unsophisticated young 
were easily shot, but the adults, even when breeding, were shy 
and hard to secure. 
2 7. Salpinctes obsoletus {Say) Caban. Rock Wren. — 
Mr. Stephens makes no mention of finding this species in Ari- 
zona during the past season, but he sends me a single specimen 
taken December 25, 1880, on the San Pedro River. 
28. Thryomanes bewicki leucogaster Baird. White- 
bellied Wren. — The collection includes five specimens of this 
form, which was apparently met with only in the Chiricahua 
Mountains and about Tucson. In the former locality it was 
common along the banks of streams where, however, it kept so 
closely hidden among the weeds and brush that it was oftener 
heard than seen. The examples before me are typical. 
29. Troglodytes aedon Vieill. House Wren. — The only 
House Wren taken is absolutely indistinguishable from many of 
my Massachusetts specimens, and I accordingly refer it here. 
Furthermore, I fail to find the characters supposed to distinguish 
var. parkmani , in any of the several California specimens includ- 
ed in my series. If the latter form really possesses any constant 
differential characters, I believe they have yet to be defined. 
169, $, near Tombstone, April 6. Length, 4.80; extent, 6.40; wing, 
2.10. “ Iris dark brown. Shot among low brush. Not common.” 
30. Anthus ludovicianus (Gm.) Licht. American Tit- 
lark. 
271, $ ad., Tucson, April 23. Length, 6.50: extent, 10.60. “Bill 
brown, paler at base below; legs brown.” Several seen in marshes along 
the stream. 
31. Helminthophila luciae (Coop.) Ridgw. Lucy’s War- 
bler. — Although this diminutive '''Helminthophila has been 
known to ornithologists for nearly twenty years, few specimens 
have found their way into the cabinets of private collectors, and 
up to the present time the species has remained a very rare one. 
On this account the acquisition of a good series of skins was 
among the main objects of Mr. Stephens’ trip, and the success 
which rewarded his labors is very' gratifying.
