HYPOTHETICAL LIST. _ Ge 
General Range.—Western United States from Illinois and Indiana west to California, 
and north into British America. Casual in migration eastward to Atlantic Coast. Winters 
from southern border of United States southward to Lower California, Mexico, and northern 
South America. 
Supposed Occurrence in Ohio.—Reported as not uncommon in Indiana during migra- 
tions, especially in the Valley of the Wabash. I have seen specimens afield near Columbus 
which I strongly suspect were of this form. 
No. 8. 
ALDER FLYCATCHER. 
A. O. U. No. 466 a. Empidonax traillii alnorum Brewst. 
Description.—‘Similar to E. pusillus, but averaging more decidedly olivaceous above, 
and more distinctly tinged with yellow beneath; the bill shorter and broader, and tarsus 
shorter” (Ridgway). (Cf. Brewster, The Auk, XIL. April, 1895, pp. 159-161). I have 
little faith in the distinctions urged, and none at all in the propriety of elaborating a sepa- 
rate subspecies because of them. Distinctions between species are puzzling enough in this 
genus, without raising the problem to the second power. 
General Range.—FEastern North America from the Maritime Provinces and New 
England, westward at least to northern Michigan, etc., breeding from the southern edge of 
the Canadian fauna northward; in winter south to Central America. 
Supposed Range of Ohio.—Not reported, because practically indistinguishable from 
E. pusillus. Should be found not uncommonly during migrations. 
No. 9. 
IVORY-BILLED WOODPECKER. 
A. O. U. No. 392. Campephilus principalis (Linn.). 
Description.—Adult male: General plumage lustrous black; tips of inner primaries 
and terminal half or two-thirds of secondaries and under wing-coverts white; a white stripe 
beginning in either cheek and proceeding upward and backward, meeting fellow on lower 
back; a hollow lengthened crest scarlet on sides and tip; nasal tufts white; bill ivory-white; 
tail graduated, the three central pairs of feathers lengthened and modified, the third pair 
fitting into the second, and the edges of all sharply decurved, thickened, and stiffened into 
six or more parallel rows of bristling barbs. Adult female: Similar but without red in 
crest. Length 19.00-21.00 (482.6-533.4); wing 10.00 (254.); tail 6.50 (165.1); head from 
tip of bill to tip of crest 6.20 (157.5); bill 2.50-2.75 (63.5-50.9). 
General Range.—Formerly South Atlantic and Gulf States from North Carolina to 
Texas north in the Mississippi Valley to Missouri, southern Illinois and southern Indiana. 
Now restricted to the Gulf States and the lower Mississippi Valley, where only locally 
distributed. 
Supposed Occurrence in Ohio.—Recorded as probable by Langdon! on authority ot 
Dr. Haymond, who found the bird in Franklin County, Indiana, not far from the Ohio line. 
No. 10. 
CORY LEAST BITTERN. 
A. O. U. No. 101.1. Ardetta neoxena Cory. 
Description.— Adult male: Similar to Ardetta exilis, but back with stronger greenish 
gloss; lesser wing-coverts at bend of wing black; brownish buff of median wing-coverts 
replaced by cinnamon-rufous; wing-quills without rufous tips; under parts distinctly rufous, 
sometimes mingled with black or white on belly and flanks; lower tail-coverts dull black. 
Female: “Similar to adult male, but crown slightly and back decidedly duller.’ Jmma- 
ture: “Similar to adult male. but black of the head and back somewhat duller, the outer 
margins of the interscannlars slightly tinged with chestnut” (Chapman). 
Nest and Eggs. similar to those of A. e-vilis. 
General Range.—Southern Florida: Ontario: Michigan; Wisconsin. 
Range in Ohio.—One record by C. C. Smith of Hamilton (doubtful). Probably not 
uncommon. “It has been found breeding in Ontario, hence its migration route must cross 
Ohio” (Jones).
