TROCHILIDJE : HUMMINGBIRDS. 



551 



turned outward ; next primary also narrowed, not so mucli as the Jst, its end obliquely incised 

 with a slight nick. Tail ample ; middle feathers scarcely or not shorter than the next, but the 

 rest rapidly graduated ; middle and several lateral ones broad, briefly acuminate, the outermost 

 narrowed linearly with rounded end. Above, including crown, golden-green ; two middle tail- 

 feathers purer shining grass-green ; lateral tail-feathers purplish-dusky, some of them with 

 narrow longitudinal chestnut edging only on one or the other web (a strong character of the 

 species : compare extensively rufous tail-feathers of the two foregoing species). Gorget glanc- 

 ing lilac-red : other under parts whitish, glossed with golden-green on sides and sometimes 

 elsewhere. Quills purplish-dusky. Length nearly or quite 4.00; extent 4.75-5.00; wing 

 nearly or quite 2.00; tail 1.35; bill 

 0.70. 9- Outer primary narrow and 

 falcate, but without special attenuation 

 at end. Outermost tail-feather nar- 

 rower than the rest, as in J* , but others 

 rounded at ends, not acuminate. Lat- 

 eral tail-feathers chestnut at base quite 

 across, then black for a space, then 

 white-tipped. Above, like ^ ; below, 

 no gorget ; throat wliite with dark 

 specks ; no green on sides, which are 

 more or less rufous, as in S. riifus 9 .

rufous below; middle tail-feathers entirely green, these having dark ends in ^ rufus; rufous 

 on lateral tail-feathers confined to their bases and of less extent than the black, while in 9 

 rufus the rufous equals or exceeds the black area ; next to middle tail-feather in 9 platycercus 

 green, with only rufous edging of outer web near base, short black end, and white tip; in 9 

 nifus the same feather is rufous on both webs to an extent equal to the green, black, and white 

 spaces all together. Though such details are not absolutely constant, they suflBce to distinguish 

 all the many specimens I have examined. Rocky Mt. region, U. S. and southward ; X. to 

 Wyoming, Idaho, Utah, Nevada; Sierras Nevadas of California; S. in winter to Guatemala. 

 AT'THIS. (Or. 'AtBIs, Atthis, Attic; also a proper name.) Attic Hummers. Crown of 

 (^ not metallic like gorget, which is prolonged into a ruff; outer primary of ^ attenuate; tail 

 graduated, the feathers rounded at end, the lateral ones black-barred and white-tipped in both 

 sexes (peculiar in this respect among North American genera). Bill only about as long as head. 

 Size very diminutive. 



Note. —A. heloixft, the Heloise Hummingbird of the Key, 2d-tth eds., 1SS4-00, p. 405, and of A. O. U. List, Ist ed. 

 188C, No. 435, proves to have been admitted upon an erroneous identification of a young specimen of Stelbiln calliope from 

 El Paso, Texas: see Ridow. Auk, Jan. 1891, p. 115; A. O. U. Comm., Auk. Jan. ISiKi, p. 111. Its place is taken by the 

 following species :
