NORTH AMERICAN BIRDS. 443 



This is precisely like the last species, but the superciliary stripe is entirely 

 white and the chin cut off from the bill by white. This subspecies breeds in Ohio. 

 It is, I believe, well named, for the majority of specimens I have taken were In 

 sycamore trees. A nest containing four eggs was found by Mr. L. C. Horton near 

 Mt. Vernon, Knox county, Ohio, June 28, 1897. The female was shot and it, with the 

 nest and eggs are in Mr. Horton's collection. The nest was placed on a horizontal 

 branch in an elm tree twenty feet from the ground, a short distance from water, 

 it is composed of fine shreds of vegetable material, intermingled with short, slender 

 twigs as the base. The eggs measure respectively as follows: .63x.52, .63x.50, .69x.53, 

 .71x.53 inches. They have the same coloration as the eggs of the Yellow-throated 

 species, D. dominica. 



664. GRACE'S WABBLEB. Dendroica gracice Baird. Geog. Dist. Southern 

 New Mexico and Arizona, and southward into Sonora. 



This Warbler was dedicated by the late Prof. Spenser F. Baird in honor of Miss 

 Grace D. Coues, sister of the eminent naturalist and scientist, Dr. Elliott Coues. 

 The nesting and eggs of this species are identical with those of D. dominica, but its 

 eggs will not be found numerous in collections. 



665. BLACK-THBOATED GBAY WABBLEB. Dendroica nigrescens (Towns.) 

 Geog. Dist. Western United States, north to Colorado and Oregon, and British Co- 

 lumbia, west to the Cascades; south in winter into Mexico, etc. 



Mr. A. W. Anthony gives this species as a summer resident of Washington 

 county, Oregon, where it frequents the thick firs. In the breeding season it is 

 quite shy and retired, inhabiting the younger growth of firs 

 and dense thickets of alder and willows. The eggs are 

 four in number. The extensive cabinet of Mr. J. Parker 

 Norris contains a set of four eggs of this Warbler, which 

 was taken in Polk county, Oregon. The nest was situated 

 in a fir tree twenty feet from the ground, and is composed of 

 fine grasses, profusely lined with feathers. The eggs are 

 pinkish-white, spotted with cinnamon-rufous and lilac-gray. 666 BLA ^ K _ THROATED

measure .67x.51, .71x.54, .71x.54, ,68x.53 inches. Mr. C. Barlow has kindly sent me 

 for inspection a nest containing four eggs of this Warbler which were taken near 

 Lakeport, Lake county, California, by Corydon Chamberlain, an account of which 

 was read in a paper before the Cooper Ornithological Club. A description was pub- 

 lished in "The Nidologist" for September, 1895. On the 5th of May the nest was 

 found compactly put together, symmetrically lined with fine hair of quadrupeds; ex- 

 ternal width three and one-third inches, external depth two inches. The nest was 

 found in a small clump of manzanitas, about four feet from the ground. The eggs 

 are white, dotted with reddish-brown and purple, chiefly about the larger end, 

 where the dots are frequently confluent, and also form small blotches. Their sizes 

 are as follows: .65x.52, ,66x.52, .65x.51, .66x.51 inches. 



666. GOLDEN-CHEEKED WABBLEB. Dendroica chrysoparia Scl. & Salv. 

 Geog. Dist. Central Texas and southward to Guatemala. 



So far as I am aware all the nests and eggs of this rare Warbler that are in 

 various cabinets have been collected in Comal county, Texas. Mr. Wm. Brewster 

 describes specimens of its nests and eggs taken by Mr. W. H. Werner in that region
