Twenty-three specimens, from Atacazo and from Pichincha (12,000 
feet to summit), Ecuador. 
Tliese little hunnningbirdti i:)rol>ably range to a higher altitude than any others in 
Ecuador. When camping on Pichincha at 14,500 feet elevation, we often saw them 
flying past our tents in a blinding snowstorm, uttering their rather harsh note, and 
taking shelter for the night under the cliffs above us, where we found their deserted 
nests under the ledges. I also saw them on several occasions at 15,500 feet, near the 
edge of the crater, but this was at times when there was little snow on the moun- 
tain. They hover close to the ground, feeding on the small obscure flowers which 
manage to flourish among the cinders and ash. The males are locally called ' ' Quinde 
negro" or black humming bird, but the females are known by the name of "Pichin- 
chanos." We never saw the two sexes together, and all the females we procured were 
shot, at from 9,000 to 10,000 feet, on the west and north sides of the mountain, but 
we saw no males at such a low elevation. 
VESTIPEDES ALINAE (Bourcier).

Two adult males from Pasto, southern Colombia. These are rather 
larger than two specimens from Bogota, and have considerably more 
of a reddish gold tinge in the malar region, but the available material 
is too limited to determine the significance of these ditferences. 
From near Pasto, south Colombia, at about 9,000 feet elevation. Local name, 
"Esmeraldas."

Three specimens from Pasto, southern Colombia. The difference in 
the color of the upper tail-coverts, assigned by Mr. Hartert to sepa- 
rate the present form from T" (hrhi/i lonf/i/'o.sfr/'s,^ is apparently of no 
value; Init the length of the bill is probabl}' sufficient for the recog- 
nition of the latter. 
Shot along the hedgerows on the south road abbve the town of Pasto. Local 
name, "Calzones negros."
