the green of tlie upper surface is more bronzy; remainder of upper 
parts much duller, the violet blue of the center of the crown barely 
indicated, the metallic coppery red of the sides of the crown extend-

TwentA'-four specimens, from Pichincha, Lloa, west side of Corazon, 
and above Milligalli, west Ecuador; Papallacta, east Ecuador; and 
Pasto, Colombia. Birds from the east and west sides of the moun- 
tains seem to be alike. The single example, an immature female, 
fioni Pasto, Colombia, differs from the others in being much more 
ochraceous below, particularly on the anterior parts, this being fully 
as conspicuous as in many specimens of L. Jafrcsnayi. 
We met with them in both ranges of the Andes at elevations of from 10,000 to 
12,500 feet, but the greater number of those we obtained were in immature pkimage, 
especially those from the eastern Andes shot in February. At times they are fairly 
plentiful around the village of Lloa, on Pichincha; and in Quito they are called 
"Pico curvo de Lloa."

Thirty-seven specimens, from Papallacta, on the east side of the 
Andes, and Pichincha, west Ecuador. There seems to be no differ- 
ence between the birds from the two sides of the mountains, but, 
judging from the present series, the Ecuador form of £. ensifera 
is worthy of subspecitic recognition. The distinction lies apparently 
in the bill alone, wdiich in the Ecuador form averages nmcli longer 
than in true etiisifera. With regard to the constancy of this char- 
acter, it may be said that out of the present series there are but ten 
having the bill not longer than the longed hllltd example from a series 
of Colombian specimens. Thus, though this difference can not be 
regarded as absolute, it is so decided and obtains in so large a majority 
of the specimens that it is full}" as worthy of recognition as similar 
differences in other cases which pass unchallenged. 
Feed on the flowers of the long Datura. The bills of the females average longer 
than those of the males. They frequent both ranges of the Andes, but personally 
we met with them only on the eastern sides of the two ranges, at altitudes between 
9,000 and 11,500 feet. Local name, " Pico largo."
