HYPOTHETICAL LIST. 643 



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 ainorum Brewst. 



Description. — "Similar to B. 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, XII.. 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. — Eastern 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 

 B. 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 1g.oo-21.0o (482.6-533.4) ;■ wing 10.00 (254.); tail 6.50 (165. i) ; head from 

 tip of bill to tip of crest 6.20 (i57-S) ; bill 2.50-2.75 (63.5-69.9). 



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. , , , t i • 



Supposed Occurrence in Ohio.— Recorded as probable by Langdoni on authority ot 

 Dr. Havmond, who found the bird in Franklin County, Indiana, not far from the Ohio line. 



No. 10. 



CORY LEAST BITTERN. 



A O U. No. igi.i. Ardetta neoxena Cory. 



Description.— ^rfa/f 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 tatl-coverts dull black. 

 Pemale- "Similar to adult male, but crown slightly and back decidedly duller." Imma- 

 ture ■ "Similar to adult male, but black of the head and back somewhat duller, the outer 

 margins of the interscapulars slightly tinged with chestnut" (Chapman). 



Nest and Eggs, similar to those of A, e.vihs. ^ 



General Range.-Southern Florir^a : 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).
