Mr. Salvin states that “ This is one o f the commonest Humming-Birds o f Coban, being found everywhere near
the city. The ratio o f the males to the females is as ten to four.”—Ibis, vol. ii. p. 271.
The following is a correct description o f the female o f this species .—
Throat and all the under surface grey ; sides o f the neck and upper surface green ; primaries purplish brown ;
secondaries deep buff, forming epaulets as in the male, but o f less size.
The
Genus C h r y s u r o n i a , Bonap.,
is composed o f six species, with pretty, golden tails. The females o f most o f them are strikingly different ; for,
although they all have the tail similarly coloured, they are destitute o f brilliancy on any part o f the body. All are
inhabitants o f the Andes in New Granada, Ecuador, and Peru, with the exception o f the C. Elides, which inhabits
countries to the northward o f Panama.

Habitat. Venezuela and New Granada.
I find no difference between the birds from Venezuela and those from the neighbourhood o f Bogota, except
that the latter have rather longer bills, and the tail-feathers lighter and inclined to green.

Chrysurisca Josephinae, Cab. e t Hein. Mus. Hein. Theil iii. p. 42, note.
Habitat. The upper parts o f the River Amazon, where specimens were procured by Mr. Bates.
I have two specimens o f a bird o f this form in my collection, one o f which, procured in Paris, is labelled
“ 0 . neera, Less. they differ from every other species I possess. They are much larger than C. Josephines, and
their tails are rich fiery bronze ; their crowns greenish blue ; all the under surface golden green ; the under tail-
coverts fiery bronze like the tail ; and the blue o f the crown extends further down the neck. I therefore retain the
name o f neera for this bird. I have still another bird allied to Josephines, with a longer wing, a shorter tail, and a
somewhat shorter bill ; the colour o f the crown is violet or purplish-blue instead o f greenish-blue, and the tail,
instead o f being rich fiery bronze, is light greenish-bronze. I cannot do otherwise than provisionally name this
bird, and I therefore propose to call it C. caruleicapilla.

Habitat. Peru.
Rich and conspicuous blue is the prevailing tint in the genera Encephala and Hylocharis, which may be
considered as truly Brazilian, since most o f the species are natives o f that country, almost the only exception being
the E. Grayi, which is found in the Andes. There is scarcely any section o f the Trochilidae less understood or
more difficult to discriminate than the next six or eight species.

Habitat. Supposed to be Cayenne.
Crown o f the head, back o f the neck, and lower part o f the back very deep dull green; throat and chest
glittering greenish blue, imperceptibly passing into the dull brownish black o f the abdomen; under tail-coverts
brown, with a wash o f dull blue in the centre o f each feather; a mark o f blue on each side at the insertion o f the
wing, forming an indistinct band across the b a ck ; upper tail-coverts bronzy green; tail steely black, rather short
for the size o f the bird, and slightly forked; wings deep purplish brown ; tarsi clothed with intermingled greyish-
white and brown feathers ; upper mandible b la ck ; basal h alf o f the under mandible fleshy, the apical half black.
Total length 3 f inches, bill i , wing, 2-jV, tail I f.
In the size o f its body, it nearly equals the Eucephala caruleo-lavata, but it differs from that and every other
known species o f this family o f birds.
I have only seen a single example o f this species.

Habitat. Eastern and Northern Brazil (Chamicuros, Hauxwell), the Guianas, Venezuela, Trinidad, and Tobago.
Specimens from all these localities are so much alike that it is impossible to consider them otherwise than as
one and the same sp ecies; but I may remark that those from Venezuela have the blue mark on the chin much less
apparent than those from Cayenne, Trinidad, and Eastern Brazil. My Chamicuros specimen also has this colour
but faintly indicated, and the tail somewhat larger.
