The FAWN-COLOURED SABRE-WING (_Platystylopterus rufus_) is about five
inches and a half long, and seven broad. In this species the mantle and
central tail-feathers are of a bronze-like green, the under side brownish
yellow, and the exterior tail-feathers brownish yellow with a black spot
near the tip. This bird is an inhabitant of Guatemala. We are entirely
without particulars as to its life and habits.

The JEWEL HUMMING BIRDS (_Hypophania_) have a powerful and slightly-curved
beak and small foot, in some instances covered with down; the wing, which
somewhat resembles that of the _Oreotrochilus_, is sometimes short,
sometimes long; in the otherwise short tail two of the feathers are
generally much prolonged.
