APPENDIX. 
specimens have been taken in several localities in the New England and Middle States. 
Nothing special is known of the habits of this species. The specimen figured in plate XXII 
was obtained for me by Mr. Purdie, and was killed at Saybrook, Connecticut, by Mr. J. 
N. Clark, on the thirtieth of May, 1879. 
HELMINTHOPHAGA BACHMANI. 
Baeliman’s Warbler. 
Helminthophaya Bachmani Cab., Jour. Orn., Ill; 1855, 475. 
Sp. Cn. Form, slender. Size, small. Color. Adult. Above, and on sides of head and neck, yellowish-green, tinged 
with ashy on crown. Patch on forehead, and beneath, deep yellow. Band across crown, throat, and upper breast, black. 
Patch on inner webs of two outer tail feathers, white. 
Observations. Known by the black throat and band on top of head. Bare on coast of South Carolina. Dimensions. 
Length, 4’50; stretch, 6'25; wing, 2'35; tail, 2'05; bill, *40; tarsus, ’65. 
HABITS. 
As far as I can ascertain, Audubon is the only ornithologist who records the actual 
capture of this very rare Warbler, in the United States, and his specimens were obtained 
in South Carolina, in July, 1833, near Charleston; therefore it is rather doubtful whether 
this bird should now be considered a bird of our section. Bachman’s Warbler is said to 
occur in Cuba. 
HELMINTHOPHAGA PEREGRINA. 
Tennessee Warbler. 
Helminthophaya pereyrina Cab., Mus. Hein.; 1851, 20. 
Sp. Cn. Form, slender. Size, small. Color. Adult male. Top and sides of head and neck, bluish-ash; remainder 
of upper parts, yellowish-green. Beneath, white slightly tinged witn greenish-yellow. Inner webs of outer tail feathers, 
edged with white. Iris, bill, and feet, brown. Female , more yellow beneath and the ash of head is obscured by greenish. 
In autumn , and Young. Similar to summer female but much more yellow beneath, and the ash of head is quite obscured 
with greenish. There is a short, dusky line back of eye, and the wing feathers are tipped with white. 
Observations. Known by the absence of any chestnut or black markings. Distributed in Summer from Northern 
Maine, northward; winters south of our limits. Dimensions. Length, 4'75; stretch, 8*35; wing, 2 55; tail, P65; bill, -90; 
tarsus, '40. 
HABITS. 
The plainly colored, little Tennessee Warbler was quite abundant in Northen Maine, 
some years ago, but has always been very rare in Massachusetts. It is, however, very 
common in Pennsylvania during autumn, but is not met with so frequently in spring, in 
this section. For other habits of this and allied species, see remarks on page 64. 
GEOTHLYPIS PHILADELPHIA. 
Mourning Warbler. 
(jf eothlypis Philadelphia Bd, , Birds N. A.; 1858, 243. 
Sp. Cn. Form, robust. Size, medium. Color. Adult male. Above, and on sides, yellowish-green. Bright yel¬ 
low beneath, with head and neck all aronnd and upper breast, black, overwashed with ashy. Female , similar but with 
the head tinged with greenish. Youny. Similar to female, but overwashed with greenish on ashy. 
Observations. Known by the dark head and neck. Occurs in summer from Maine, northward; wintering south of 
our limits. Dimensions. Length, 5'50; stretch, 7'80; wing, 2'45; tail, P90; bill, ‘75; tarsus, -45. 
HABITS. 
The Mourning Warbler is quite rare, both in Pennsylvania and Massachusetts, in 
spring and fall, but is not uncommon in Maine, frequenting thorny thickets, and behaving- 
much like the Maryland Yellow-throat. The song is, however, much finer than that of 
the latter named species, being a long, clear warble, and is given early in the morning, 
while the bird is perched in some slightly elevated situation. 
OPOROHN1S AGILIS. 
Connecticut Warbler. 
Oporornis ayi/is Bd., Birds N. A.; 1858, 246. 
Sp. Cii. Form, slender. Size, medium. Color. Adult male.. Above and on sides of neck and sides, dark yellow
