21. Pigeon Hawk. Saw one. 
22. Carolina Dove. A few. 
23. Turnstone. Only one seen. 
One important conclusion which can be drawn from these observations 
seems to be that instead of following the land a large number of species 
migrate direct from Central America to the Mississippi Valley across the 
Gulf of Mexico, and the scarcity of these species in Southwestern Texas is 
thus explained. — A. M. Frazar, Watertown , Mass. 
Additions to the Avi-fauna of the United States. — During the 
spring and early summer of 1881 the following birds, which are either 
new to the United States, or for the first time definitely ascertained to 
have been taken within their limits, were collected for me in Southern 
Arizona by Mr. F. Stephens. A simple list is here given, as there is not 
at present time to prepare a more detailed consideration of these, as well 
as many others of great interest, which will be fully considered in a future 
number of this Bulletin. 
1. Parus meridionalis. Scl. Mexican Chickadee.— Hab., highlands 
of Mexico; Arizona (Brewster). Several specimens taken in March 
among the Chiracahua Mountains, where the species was found to be not 
uncommon. 
2. Myiarclius cooperi {Kauft) Baird. Cooper’s Flycatcher. — 
Hab., Southern and Western Mexico (Tehauntepec, Yucatan, Mazatlan, 
etc.) Ascertained to be an abundant summer species about Camp Low- 
ell. Numerous specimens taken between May 31 and June 25. 
This species is true cooperi of Kaup and is not to be confounded 
with “ cooperi erythrocercus ” of the Lower Rio Grande Valley in Texas. 
3. Myiarchus lawrencei ( Giraud ) Baird. Lawrence’s Flycatcher. 
— Hab., Northern Mexico, from northern boundary south to Colima, Te- 
hauntepec, Yucatan, and Salvador. Eight specimens taken in the Santa 
Rita Mountains between May 12 and May 17. These captures confirm 
still another of Giraud’s alleged- sixteen Tekas species. — William Brew- 
ster. Cambridge , Mass.
