136 Genera of Humming Birds. 



Habitat. — Columbia. 



Male. — Upperside shining grass-green. Underside glitter- 

 ing bluish-green in some specimens; in others, glittering 

 yellowish-green. Median rectrices bronzy-green, lateral pur- 

 plish-black. Undertail-coverts shining green, narrowly edged 

 with grayish-white. A tuft of white feathers on sides of anal 

 region. Wings purplish-brown. Maxilla black. Mandible 

 flesh colour with black tip. 



Total length, 3|in. Wing, 2. Tail, if. Culmen, -J--J-. 



Female. — Upperside bronze-green. Underside grayish- 

 white washed with green feathers on sides of breast, abdomen 

 and flanks. Median rectrices bronzy-green, lateral purplish- 

 black, tipped gray. 



Very abundant in Columbia, where it was discovered by 

 the naturalist Goudot, who explored Columbia during many 

 years. He died in that country. It is probable that many of 

 the Columbian species of Humming Birds were sent first to 

 Europe, by him, and by Boissoneau. 



I have put C. luminosa, Lawr as a synonym of C. goudoti ; 

 because I have many specimens which correspond exactly to 

 his description of that species, and I consider them all, as C. 

 goudoti.
