on old data, I have deemed it unnecessary to go over any of the 

 ground trodden by Mr. Ridgway in his elaborate and invaluable 

 monograph of the genus Scops * but the bearing of some of the 

 present testimony has proved so far reaching that I venture, in 

 concluding, to suggest the following rearrangement of the North 

 American Screech Owls belonging to the S. asio group. 



Dichromatic: erythrisnial phase bright rufous. 



Scops asio. Habitat, United States north of the Gulf States and east 

 of the Rocky Mountains. 



Scops asio Jloridanus. Habitat, Florida and Southern Georgia. 



Scops asio 7naccalli. Habitat. Highlands of Guatemala, Eastern Mex- 

 ico, and Valley of the Lower Rio Grande in Texas. 



Dichromatic: erythrismal phase tavjuy or reddish hrozvn. 



Scops asio kcnnicotti. Habitat, Northwest Coast from Sitka to Oregon 

 and eastward across Washington Territory into Idaho and Montana. 



JVon-dickromatic: altvays gray in color. ^ 



Scops asio bettdirei. Habitat, Coast region of California. 

 Scops asio tricopsis? Habitat, Western Mexico and the extreme south- 

 western border of the United States. 



Scops asio maxzvellcE. Habitat, Mountains of Colorado. 



A RECONNOISSANCE IN SOUTHWESTERN TEXAS. 



BY NATHAN CLIFFORD BROWN. 



The village of Boerne in Southwestern Texas, with its environ- 

 ing country, was the field of my ornithological labors between 

 December 3i, 1S79 and April 4, 1S80. Boerne is situated about 

 thirty miles northwest of San Antonio, and less than that distance

 Vol. I, pp. 85-117. 



t This arrangement leaves a large portion of the Middle Province without any 

 characteristic representative, maxivellce being an Alpine form apparently confined to 

 the Rocky Mountains, while kennicotti and "tricopsis" respectively invade only its 

 northern and southern borders. Our knowledge of the subject is not as yet sufficiently 

 comprehensive to enable me to fill this gap, but all the available evidence goes to 

 show that asio, at least as above defined, is not found to the westward of the Rocky 

 Mountain range.
