124 MR. GOULD ON SOME NEW BIRDS. [April 8, 
Mr. Gould exhibited to the Meeting and described two new spe- 
cies of Humming-Birds, which he had recently received from Ecuador ; 
a new Fregilus from the Himalayas, which had hitherto been re- 
garded as identical with the European bird of that form ; and a spe- 
cies of Prion, which appears to constitute an additional member of 
that peculiar genus of oceanic birds. 
The Humming-Birds were named, respectively, Heliothrix longi- 
rostris and Aphantochroa hyposticta ; the Fregilus, F. himalayanus ; 
and the Prion, P. magnirostris ; and were thus described :— 
HELIOTHRIX LONGIROSTRIS, Gould. 
Male: upper surface and wing-coverts brilliant green; wings 
dark purplish brown ; four middle tail-feathers bluish black, the re- 
mainder pure white ; lores, line under the eye, and ear-coverts velvety 
black, terminating in a small tuft of violet-blue feathers ; below the 
black line a stripe or moustache of glittering green; chin, throat, 
and under surface snow-white; bill black; legs and feet fleshy 
brown. ; 
Total length 5} inches; bill 1,4,; wing 22; tail 2}. 
Hab. Ecuador. 
Remark.—I have been for years receiving from Ecuador examples 
of what I believed to be females of a new species of Heliothrix ; but 
now in 1862 I have received an adult male, which convinces me that 
my opinion was correct, and I have therefore described it under the 
above appellation. In comparison with the other species of the genus, 
I find it to be most nearly allied to H. auritus, being similarly co- 
loured to that bird; it is, however, of larger size, has a considerably 
longer bill, and in my specimen, which is doubtless adult, the crown 
is devoid of the glittering hue seen in H. auritus; at the same time, 
it is somewhat brighter than the back. 
APHANTOCHROA HYPOSTICTA, Gould. 
All the upper surface, wing-, and tail-coverts deep green; wings 
purplish brown ; tail dull purplish green, deepening into blackish 
brown at the tip, the two outer feathers on each side very slightly 
fringed with white at the tip; feathers of the throat, breast, and 
centre of the abdomen dull white at the base, with a spot of dull 
green near the tip, giving those parts a spotted appearance; re- 
mainder of the under surface dull green ; under tail-coverts dull green 
at the base, deepening into black near the end, and fringed with 
grey; tarsi and thighs rather thickly clothed with white feathers ; 
bill black, except at the base of the under mandible, which appears 
to have been flesh-colour. 
Total length 43 inches ; bill 1,3,; wing 23; tail 12. 
Hab. Ecuador. 
Kemark.—I have several specimens of this bird all similarly co- 
loured ; and I believe the specimen from which the above description 
was taken to be fully adult. It differs from A. cirrhochloris in its 
spotted breast, in its shorter tail, and its rather more lengthened and
