mality, evident!}^ tending toward albinism. The upper parts and 
posterior lower surface are almost uniform pale brown, though some-- 
what liohter on the lower back; the wings, tail and auriculars are of 
a darker shade of the same color; the tiliial tufts are white, as usual; 
while the throat is dull metallic brown, slightly darker and more rufes 
cent than the color of the upper surface. 
These hummingbirds have a pretty habit of suddenly rising from the tops of the 
bushes for some yards into the air, where they remain poised for a few seconds, 
uttering some very sweet notes, then suddenly descend. Often two would meet thus 
in the air, but only the males do this. Local name, "Tijerettas" — scissortail.

Ocreatus cissmnis Hartert, Tierreich, IX, 1900, p. 151. 
One adult male from Baeza, east Ecuador. 
Confined to the eastern side and rare at Baeza. The single specimen we obtained 
was feeding on the flowers of a small ground plant close to our hut. 
UROSTICTE BENJAMINI (Bourcier). 
Trochihis be^yamini BouRCiER, Compt. Rend. Ac. Sci., XXXII, 1851, p. 187. 
Urosticte benjamini Gould, Mon. Troch., Ill, 1853, pi. cxc. 
Twelve specimens, from Gualea and Santo Domingo, west Ecuador. 
One of these is an immature male and differs from that of Urost!cte 
rufierissa., as do the females of these two species — in the color of the 
crissum. 
Local name, "Cinco reales" — five reals; but why they are called l)y such a curious 
name I was unable to find out. 
ADELOMYIA MELANOGENYS MELANOGENYS (Eraser). 
TrochUus melanogru IIS FnxsER, Proc. Zool. Soc. Lond., 1840, p. 18. 
Adelornyia mdanogenys Sclater, Proc. Zool. Soc. Lond., 1859, p. 145. 
Fourteen specimens, from Papallacta and Baeza, east Ecuador. 
ADELOMYIA MELANOGENYS MACULATA (Gould). 
Adelornyia maculata GovLT), Mon. Troch., Ill, 1861, pi. cxcix. 
Adelornyia melanogenys maculata Haktert, Tierreich, IX, 1900, p. 155. 
Thirteen specimens, from above Milligalli; Canzacota; and the west 
side of Pichincha, west Ecuador. These bear out the differences men- 
tioned by Hartert^ as separating this form from true melanogenys of 
the east side of the mountains. 
Very silent birds, which seem to spend most of their time sitting alwut on the 
bushes and branches near the ground, a trait that has earned for them the native 
name of "Muertes."
