Alabama, and terminates near Mobile (this terminal point is 
arbitrary); while in Texas it is resumed in the southwestern 
portion of the range of mecallii? 
Next to this belt comes that wherein both phases occur, but 
where the gray predominates. It begins near Belfast, Maine, 
follows the exclusive gray belt with irregular outline to its ter- 
mination in northern Kansas, and continues southward ina 
broad belt into Louisiana, where it is a question whether or 
not it becomes broken at New Orleans. Immediately north 
of New Orleans it begins again at Mandeville, La. (based on 
specimens in Am. Museum), and continues eastward to the 
coast in the neighborhood of Savannah. In its northern half 
it sends a long arm southward, through eastern Massachusetts, 
into central Rhode Island and Connecticut, again in Western 
Pennsylvania, it reaches in a narrow strip far down the Alle- 
ghanies into Virginia and West Virginia, terminating near 
latitude 37°, covers practically the whole of Ohio, with a good 
share of Indiana, and continues thence to Leavenworth, Kan- 
sas, the delta of the Mississippi, and to the Atlantic. 
Within this area lies the region in which both forms occur, 
but in which red largely predominates (which in turn includes 
the exclusive red areas), and which occupies nearly one-half 
the area inhabited by asio proper. It of course conforms to 
the outline of the last described belt, and extends along the 
entire Atlantic coast from New England to Savannah. 
Lastly are the two areas where red is the exclusive form. 
The one of considerable size and importance based upon sub- 
stantial evidence, lies wholly within the Mississippi Valley: 
the other, a small strip, extends from a little northwest of 
Oakdale, North Carolina, to Variety Mills, in Virginia, and 
including Wytheville. At present the grays are apparently 
unknown from these areas. It has been impossible to examine 
material from either, and to those who may have the oppor 
tunity, I would point out the desirability of collecting all the 
specimens possible. 
* The intermediate region is mapped upon very insufficient data, it being next to 
impossible to learn anything of this territory, but the best has been done that was pos- 
sible under the circumstances,
