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 aro appearing, with the generally more vivid 
tints of the adult, but 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 Lophomis 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
