Iviii INTRODUCTION. 



New York, has made us acquainted with a second species in his lolama frontalis. Both these birds inhabit the 

 eastern slopes of the Andes of Ecuador and forests bordering the River Napo. 



106. lOL^MA FRONTALIS, LawT, . . . . . . . . . . . . Vol. 11. PL 92. 



Habitat, The head-waters of the Napo. 



107. lOL^MA SCHREIBERSI Vol. 11. PL 93. 



Habitat. The forests bordering the Upper Rio Negro and the Napo. 



The species composing the Andean genera to which the names oi Heliodoxa and Leadbeatera have been given, 

 are all truly beautiful birds. They are of large size, and have certain parts of their plumage more than usually re- 

 splendent,— so much so, indeed, that no bird has yet been found which equals them in this respect. From Vene- 

 zuela and New Granada on the north to Bolivia in the south, the various members of these genera find a congenial 

 habitat. 



Genus Heliodoxa, Gould. 



("HAioy, sol, et 86^aj gloria.) 

 Generic characters. 



Male. — Bill longer than the head, straight and cylindrical ; wings long and pointed ; tail ample and forked ; 

 tarsi clothed ; feet small ; hind toe shorter than the middle one ; nails feeble ; centre of the throat blue, surrounded 

 by brilliant green. 



Female, — Unadorned. 



108. Heliodoxa JACULA, Gow/c? ......<..,., Vol. II. PL 9^4 . 



Coeligena jacula, Reichenb. Troch. Enum. p. 4, pi. 688. fig. 4522. 



Heliodoxa jacula, Cab. et Hein. Mus. Hein. Theil iii. p. 22. 

 Habitat. New Granada. 



109. Heliodoxa Jamesoni <,....,...... Vol. II. PI 95 



Habitat. Ecuador. 



Hitherto I have entertained the opinion that the H. jacula and the Leadbeatera grata were of the same form • 

 but upon further consideration I now believe them to be distinct ; and as the former is the type of my genus Helio- 

 doxa, I retain that of Leadbeatera for the other. 



Genus Leadbeatera, Bonap. 

 Of this form I possess three very distinct birds, which might be considered by some persons as one and the 

 same, but in this opinion I cannot agree : the L. Otero from Bolivia, and the L. grata are too unlike to be considered 

 otherwise than as separate species ; while the third, which is from Venezuela, is aUied to the Bolivian bird rather 

 than to that from New Granada.

Habitat. Peru and Bolivia. 



111. Leadbeatera splendens, Gould, 



Centre of the crown briUiant blue, bordered on each side with jet-black ; upper surface bronzy green ; wings 

 purphsh brown; two centre tail-feathers bronzy, the remainder black; under-surface glittering green; under tail- 

 coverts olive-grey ; bill black ; feet dark brown. 



Total length, 5^ inches ; bill 1-pV ; wing 2^ ; tail 1\ ; tarsi \. 



Habitat. Venezuela. 



This species is very nearly allied to the Leadbeatera Otero, but it difi^ers in having a straighter and shorter bill, 

 and in the green tint of the under-surface. •
