breast and vent as in the male ; tail coverts green ; 

 tail as in the other sex ; the two middle feathers or 

 one colour, the rest with a white spot at the tips." 

 In a specimen of a young female which Lesson has 

 figured, the tail is only slightly rounded, having the 

 outer feathers tipped with white ; the upper parts are 

 of a greyish green, and the lower part of the plumage 

 is of a chaste grey, palest on the throat and vent." 



Lesson has also given two representations of the 

 young males. In these the bright scaly feathers of 

 the throat are appearing, with the generally more vivid 

 tints of the adult, hut the tail assumes very little of 

 its wedge-shaped form. 



Mr Swainson forms from this bird his genus Se- 

 lasphorus, which I believe would be before the in- 

 stitution of Lesson's title of Lophornis for the same 

 group, and includes all those magnificent species ha- 

 ving tufts of feathers issuing from the sides of the 

 neck, of which the Tufted-necked Humming-Bird 

 was so long the most familiar example ; and also the 

 Trochilus platycercus, which has been described in 

 the Philosophical Annals, with a Synopsis of Mexi- 

 can Birds ; it is characterised as green above, beneath 

 whitish ; the chin and throat amethystine red, the 

 tail rounded, with the four centre feathers very 

 broad. 



Vieillot's Humming-Bird will also range here, and 

 we may now mention, that since the publication of 

 our First Volume, another figure has been given by- 

 Lesson, in which the neck tufts are represented at
