252 General Notes. 



21. Pigeon Hawk. Saw one. 



22. Carolina Dove. A few. 



23. Turnstone. Only one seen. 



One important conclusion which can he 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 1SS1 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. Myiarchus cooperi (Kaup) Baud. 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 eryiirocercus" 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 Texas species. — William Brew- 

 ster. Cambridge, Mass.
