greenish-black. Throat metallic violet-blue, encircled with a 

 narrow band of black. A triangular large spot of brilliant 

 metallic green in the centre of the lower part of throat, just

 narrow metallic blue band under the green, and another black 

 band under the blue one. Breast, abdomen, and flanks pure 

 ^j^ite — the latter sparingly spotted with olive-green feathers. 

 In the centre of the abdomen a line of brownish-black.

Female. — Upperside olive-green. Median rectrices dark 

 bronzy-green, next one of the same colour sometimes with 

 white tips, laterals white at base, passing to greenish-brown, 

 and with white tips. Throat white, minutely spotted with 

 brown-olive, rest of underside pale olive-brown margined 

 with white. Same size as the male. 



For a long time, this species, discovered by Delattre, on the 

 Volcano of Chimborazo, has been very rare in the collections ; 

 but in 1885, the well-known collector, Henry Buckley, brought 

 to Eno-land a large series of this species, and of O. picJiincha. 



All my specimens were collected by him.

Habitat. — Volcano of Pichincha, Ecuador. 



Male. — Exactly like the preceding species, without any 

 green on the throat. 



Total length, sJin. Wing, 2|. Tail, 2%. Culmen, f. 



Female. — Like that of O. Chimborazo, slightly whiter on 

 throat, and more minutely spotted. Without knowing the 

 exact localities where they come from, it is nearly impossible 

 to distinguish the females of one species from another. 



This fine species was discovered in Ecuador, by the late 

 Bourcier, who was then, French Consul in Quito. 



All my specimens were collected by Buckley.
