Sp. Char. Tail moilorately forked ; the foathcrs acutely pointed. Third quill lonpe.st. ; 

 second and then fourth a little shorter. Fir.st much shorter than fifth, a little longer than 

 sixth. Bill very slender ; dark brown. Above dark olivc-};reen, considcr.ably darker on 

 the head. I3reast and sides of the body light olive-green, the throat grayish-while ; 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 the outer edge a little paler than elsewhere, but not at all whit«. Length, 

 5.50; wing, 2.80; tail, 2.50 ; tarsus, .07. 



Had. Mexico and Western Province of United States (Clark's Fork; Fort Laramie; 

 Fort Tcjon, Orizaba, and numerous iiitermccliatc points). North to Lesser Slave l^ake, 

 where breeding abundantly (S. Jonks, Sins. S. L). Localities: Vera Cruz, winter, 

 perhaps resident (Sum. M. B. S. I, 557) ; W. Arizona (Coues, P. A. N. S. 1800, 02). 



In tills species the olive-green on the sides is scarcely distinguishal)lo, 

 from that on the l)ack, although liecoming more yellow on the middle of the 

 breast. Tiiere is a decided ashy shade on the whole head. The only light 

 edging to the ijuills is seen on the terminal half of the secondaries. The 

 upper mandililc and feet are black ; the tip of the lower (and in one speci- 

 men the whole) dark brown. . Tiie fork of the tail measures a quarter of an 

 inch in depth ; the longest quill exce'-,ds the first by .40. 



This species is at once distinguishable from all t'le North American 

 T//mii.nn/as, except ohsrvnis, by the extreme narrowness as well as shortuess 

 of the bill. This is only .25 of an inch wide at the posterior angle of the 

 mouth, and only .19 at the nostrils. Tts colors above are those of amdicus, 

 wliile the general effect is much more that of Jlariventris, 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 

 mucli more continuous and distinct ; tlie bands on the wings dull grayish 

 instead of clear greenish-yellow. Tlie tail, instead jf being nearly even, is 

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

 yellow, beneath. The tarsus has tlie same peculiar scutellatioii. 



The differences from T. ohscurus are less easily expressed. It is, however, 

 considerably smaller, and more olivaceous above and below, the tarsi very 

 much shorter ; the most tangible cliaracter is seen in the absence of the
