BIRDS — TYRANNINAE — EMPIDONAX HAMMONDII. 



199 



That this species is not the T. pusilla of Swainson is sufficiently evident from the fact that 

 the bands on the wing in the hitter are said to he grayish wliito, the throat asli gray, a whitisii 

 ring round tlie eye, &'C.; all tliese parts in Jiaviveiilris being strongly tinged with yellowisli. 

 The proportions of the quills, too, are diUcrent. 



1 have quoted Tyrannula pusilla of Reiulmnlt and (ilogL'r, a species capturni in hsfjl) in the 

 Godthaab district of Greenland, as coming much nearer to tlie present species tlmn to i^us'dla 

 of Swainson.

EMPIDONAX HAMMONDII, Baird. 



Tyrannula Aaminondit, De Veset, Pr. A. N. Sc. May, 1858. 



Sp. Cn. — Tail moderately forked ; the feathers acutely pointed. Third quill longest ; second and then fourth a little shorter. 

 First much shorter than fifth, a little longer than si.xth. Hill very slender, dark brown. Above dark olive green, consider- 

 ably darker on the head. Breast and sides of the body light olivo green, the throat grayish white; the rest of under 

 parts bright sulphur yellow. A whitish ring round the eye. Wings and tail dark brown ; the former with two olivaceous gray 

 bands across the coverts; the latter with tlie outer edge a little paler than elsewhere, but not at all white. Length, 5.50; 

 wing, 2.80 ; tail, 2.50 ; tatsus, .G". 



llab. — Vicinity of Fort Tejon to Los Angeles. 



In this species the olive green on the sides is scarcely distinguishable from that on the back, 

 although becoming more yello.w on the middle of tlie breast. There is a decided ashy shade on 

 the whole head. The only light edging to the i^uills is seen on the terminal half of the 

 secondaries. The upper mandible and feet are black; the tip of the lower (and in one specimen 

 the whole) dark brown. The fork of the tail measures a quarter of an inch in depth ; the 

 longest quill exceeds the first by .40. 



This species is at once distinguishable from all the North American Tyrannulas, except 

 dbscurus, by the extreme narrowness of the bill. This is only .25 of an inch wide at the 

 posterior angle of the mouth, and only .19 at the nostrils. Its colors above are those of 

 acudicus, while the general efl'ect is much more that of Jlaviventris, although less briglitly 

 olive. The throat is grayish, not of the same yellow with the belly ; the ring round the eye 

 white, not yellow ; the olive of the breast much more continuous and distinct ; the bands on 

 the wings dull grayish instead of clear greenish yellow. The tail, instead of being nearly 

 even, is quite deeply forked. The bill is scarcely half as wide, and brownish, not yellow, 

 beneath. The tarsus has the same peculiar scutellation. 



Tiie differences from T. obscurus are less easily expressed. It is, however, considerably
