Plate 489. Falco-leucoptcrus, Temm. Inhabits Eastern Asia, and 



discovered by Dr Van Seibold M. Temminck remarks, that it 



will form the passage from the True Eagles, with feathered tarsi, 

 to the Sea Eagles. The tarsi of the present species are feathered 

 for half their length; and the other parts, ta judge from^ the plate, 

 are intermediate modifications of form. The forehead, the upper 

 half of the wings, the pinion to the greater coverts, the thighs, 

 belly, and tail are pure white, the rest of the plumage brownish 

 black. 



Plate 490. Mycropogon margaritaius. Temm, Also figured by M. 



Riippell, tab. 20 Temminck has formed from this and five 



other species, all found in the old world, his genus Mycropogoriy 

 and gives his usual nominal monograph of the species. We dislike 

 the way in which the monographs are given in this otherwise* 

 useful work. The species is only named if a new one, and the 

 native country mentioned, as if every one, on the receipt of some fresh 

 collection, were, through ornithological instinct, to know the species 

 from a local habitation and a name. It answers very well for a 

 general view, where the species have been figured or described, and 

 these references are always given, but in the other case it is worse 



than useless Mycropogon fuliginosus, Temm. Nov. spec, from the 



west coast of Borneo, is also described under this plate. The length, 

 about five inches and a half; upper parts, dull amber brown ; throat, 

 and fore part of the neck, ferruginous ; belly, yellowish white, tinged 

 on the flanks with brown. 



Plates 491 and 492. Perroquet Huet. and P. Pretre. Two beautiful 

 species. The description deferred. 



Plate 493. Phasianus versicolor, female. Male figured in a former 

 livraison. No description of female. 



Plate 494. Head and neck of Cathartes Gryphus, Temm., the Condor, 

 of the natural size and colours, taken from a living specimen in the 

 royal menagerie at Paris. 



Plate 495. Falco regalis, Temm. " Cette grande espece du nord 

 de I'Amerique est absolument modelee sur les formes de notre 

 autour d'Europe, si ce n'est que les dimensions chez celle du 

 present article sont d'un tiers plus fortes. Nous ne connaissons pas 

 encore les etats diiFerens de I'age, et de la mue de ce bel oiseau, 

 donne ici sur I'examen d'un sujet unique, revetu de la livree parfaite 

 de I'etat adulte." 



Such is the commencement of M. Temminck's description of this 

 species ; and we cannot help thinking, that the name he has adopted 

 has been rather premature. He acknowledges the examination of a 

 single specimen only ; and a slight diflference in size, with a little 

 feathering on the tarsi, is scarcely a sufficient specific distinction. 



The length of M. Temminck's specimen is two feet one inch. 



Plate 496. Falco exilis, from South Africa, and about the size of our 

 common sparrow hawk. The colours of the upper parts, also, nearly 

 agree with our species, but the under parts differ entirely, being 

 without either bars or longitudinal streaks. The throat and belly 

 are pure white; the cheeks, breast, belly, and thighs, uniform 

 ferruginous. 



Plate 497. Turdus amaurotis, Temm. Sent from Japan, by Seibold j 

 length about 9^ inches ; upper parts bluish gray, with the centre of 

 the feathers on the head and neck of a lighter shade ; a rather 

 broad curved streak of rich brown passes from the eye over the 

 auriculars, and upon the sides of the neck ; wings, brownish ;
