and forked, the feathers narrow and unyieldmg ; tarsi partially clothed ; feet small ; hind toe long ; nail moderate ; 

 face luminous. 



Female, — Unadorned.

Habitat, Ecuador. 



" Professor Jameson's specimens of this fine bird were obtained in the neighbourhood of Auca, on the road to 

 Nanegal, at about 6000 or 7000 feet elevation. They were feeding on the A Is tr center ice. Datura not being found in 

 that locality." — Jameson and Fraser in Ibis, vol. i. p. 400. 



The members of the genus Helianthea, distinguished by their star-like frontlets and luminous under- surfaces, 

 appear to range next to the preceding. Three of them (namely, H. typica, H. Bonapartei, and H. Eos^ are quite 

 typical ; but the H. Lutetice and H, violifera differ somewhat in their colouring, the lower part of the body of the 

 two latter species not being luminous, while they assimilate in all other respects. Dr. Reichenbach's separation of 

 the H, typica and H, Bonapartei into a separate genus (^Hypochrysa') cannot, in my opinion, for a moment be admitted. 



Genus Helianthea, Gould, 



("HA^off, sol, et av6o9, flos.) 

 Generic characters. 



Male. — Bill long, straight and cylindrical ; wings moderately long and powerful ; tail of medium size and slightly 

 forked when closed ; tarsi extremely short and clothed with feathers ; feet very small ; hind toe the shortest ; fore- 

 head and under-surface luminous. 



Female, — Destitute of luminous colouring. 



The members of this genus frequent the Andes for at least eight degrees on each side of the equator.

Trochilus porphyrogaster, Licht. in Mus. of Berlin. 



Habitat, New Granada. Is exceedingly common in the neighbourhood of Bogota. A large race occurs near 

 Pamplona.

Hypochrysa Bonaparti, Reichenb. Aufz. der Col. p. 9 ; Id. Troch. Enum. p. 6, pi. 739. figs. 4683-84. 

 Trochilus chrysogaster, Licht. in Mus. Berlin. 



Habitat, New Granada. Examples frequently occur in collections from Bogota. 



262. Helianthea Eos, Gould Vol. IV. PI. 237. 



Habitat. Paramos da los Conejos, near Merida in Columbia. 



263. Helianthea Luteti^ Vol. IV. PI. 238. 



Habitat, Popayan and Ecuador. Professor Jameson and Mr. Fraser state that "This bird is found in the 



valleys of Lloa and Pelogalli, but not nearer Quito." — Ibis, vol. i. p. 400. 



264. Helianthea violifera, Gould Vol. IV. PL 239. 



Habitat, " In provinz Chulimani au Cordilera " in Bolivia (Warszewicz). 



Genus Heliotrypha, Gould, 



("HAioy, sol, et Tpv(f)rj, luxuria.) 

 Generic characters. 



Male,— Bill straight and of the same length as the head; wings rsithev long; tail long and forked; tarsi 

 partially clothed ; feet small ; hind toe rather shorter than the middle one ; forehead and throat luminous. 



Female. — Destitute of luminous colouring on the throat. 



The members of this genus, two in number, differ from those of Heliangelus in the absence of any band of 

 white on the chest and in having a lengthened and deeply-forked tail.
