naming it 7’. sylvestris, had reference apparently to the name ‘‘ Wood-Wren,”’ 
given by Audubon to ‘“‘ 7’. Americamus.’”’ The latter author and Nuttall both 
considered it nearest to 7’. hyemalis, instead of 7. edon, from which confusion 
resulted; and Dr. Heermann, in quoting T. Americanus from California, as 
well as J. edon, seems to have meant the American race of the ‘‘ European 
Wren” (7. Europeus Cuv.), which is T. hyemalis. I have seen the latter 
recently just north of S. F. Bay, near the sea-level, in Sept., and down to 
lat. 35° from Nov. to March. 
HELMINTHOPHAGA CELATA—Orange-crowned Warbler—p. 83—(var. lutescens 
Ridgw.). The nest and eggs described by Audubon, as quoted by me, must 
have belonged to some other bird. On May 25th, 1874, I found a nest near 
Haywood, Alameda Co., built on the ground among dead leaves, on a steep 
slope in the woods, very similar to that of the eastern-variety found by Ken- 
nicott, and I shot the female for identification. The three eggs, probably a 
second brood, are clear white, densely spotted with brownish-red specks; 
size 0.50 by 0.60 inch. They were partly hatched, and probably a second 
brood. 
Drenpraca AupuBoNtI—Audubon’s Warbler—p. 88. This species, having 
the greatest adaptability to different climates and foods, far outnumbers all 
the others. In winter I have seen them pecking at dough and other food 
thrown out of doors, besides fruit-skins, and green herbage. 
DeENDR@CA CoRONATA—Yellow-crowned Warbler—p. 89. A female of this 
species was killed in Oakland, Cal., in the winter of 1872-3, and I shot a very 
perfect male at Haywood, April 10th, 1875. As they winter as far north as 
New York, those of this coast may spend that season chiefly north of the U. 
S., or in the mountains. The nest and eggs, as quoted from Audubon’s de- 
scription, are considered by Dr. Brewer as belonging to some other bird— 
(See N. A. Birds, I. 228). 
Drnpraca TowNsENDI—Townsend’s Warbler—p. 91. I saw one of this 
species at Haywood as early as Sept. 12th, 1875, in company with several of 
our summer warblers; so that it is probable that some of the species may 
breed not very far to the north. I saw no more until Dec. 5th. 
GEOTHLYPIS TRICHAS—Yellow-Throat—p. 95. As I suspected, this species 
winters in great numbers in California, between lats 38° and 35°. I found a 
nest near Saticoy, Ventura Co., containing young on Apr. 22d, nearly as ear- 
ly as I before recorded them as migrating near San Diego. I have seen none 
in summer in the windy region around 8S. F. Bay, though a few winter there. 
Myropi10ctEs PUsILLUS—Black-capped Warbler—p. 101—(var. pzleolatus Pax- 
Las). Although described by Baird in N. A. Birds, I. 319, as having a short- 
er wing and tail than the eastern var., the measurements and remarks in Pa- 
cific R. R. Rep. (Birds IX, p. 293) indicate the contrary, as well as larger 
size, according to the usual rule in west coast varieties. 
As suggested by me, the arrival of this species in California is usually much 
earlier than observed in 1862, as I found them in 1873 near Saticoy, lat. 359, 
on March 18th, the males migrating north in large numbers, and singing
