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 : erytkrismal phase bright rufous. 
Scops asio. Habitat, United States north of the Gulf States and east 
of the Rocky Mountains. 
Scops asio floridanus. Habitat, Florida and Southern Georgia. 
Scops asio maccalli. Habitat, Highlands of Guatemala, Eastern Mex- 
ico, and Valley of the Lower Rio Grande in Texas. 
Dichromatic: erythrismal phase tawny or reddish brown. 
Scops asio kennicotti. Habitat, Northwest Coast from Sitka to Oregon 
and eastward across Washington Territory into Idaho and Montana. 
Non-dichromatic: always gray in color .f 
Scops asio bendirei. Habitat, Coast region of California. 
Scops asio iricopsisf Habitat, Western Mexico and the extreme south- 
western border of the United States. 
Scops asio maxwellce. 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 21, 1879 and April 4, 1880. Boerne is situated about 
thirty miles northwest of San Antonio, and less than that distance

Vol. I, pp. 85-117. 
f This arrangement leaves a large portion of the Middle Province without any 
characteristic representative, maxwellce 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.
