Habitat. — Chiriqui, Columbia. 



Male- Forehead metallic ruby reel. Crown pure white with 

 elongated feathers on the occiput, forming a crest. The few 

 narrow lengthened dark metallic green feathers, mentioned by 

 Mr. Daniel Gr. Elliot, on each side of the occiput, do not exist 

 in the male specimen which I possess. These feathers exist on 

 each side of the neck, they are very long and ornament the 

 throat in a peculiar manner. Upperside bronzy-green. Rump 

 dark purple crossed by a narrow pale rufous band. Throat 

 metallic grass-green. Breast pure white. Abdomen, flanks and 

 undertaii-coverts rufous, with a few bronzy-green feathers on 

 flanks. Median rectrices rufous edged with bronzy-green, 

 lateral rufous with external edges bronzy-green. Wings 

 purple. Bill, flesh color, with black tips. 



Total length, 3-in. Wing, 11. Tail, l}. Culmen, |. 



Female. — Head dark brown. Upperside bronzy-green. Throat 

 and breast white, spotted with brown. Tail deep buff with a 

 subterminal black bar. Flanks bronzy-green. Abdomen and 

 undertaii-coverts deep rufous. Rump as in the male. 



This exceedingly rare and charming species was discovered 

 at Bugaba, near the Volcano of Chiriqui, by Mr. Arce, a native 

 of Guatemala, to whom Science is indebted for several new 

 species. 



I have only one male specimen, sent to me by Mr. Arce.

 elongated feathers extending over the rufous at base with a
