delalande’s humming- uird. 
shining green ; the vent and flanks are gray ; the 
wings are brownish purple ; the centre feathers of the 
tail of the colour of the upper parts ; the remaining 
feathers are dull blue, and the outer feathers have a 
conspicuous -spot of clear white at the extremities. 
The female is nearly of the same size with the 
male, but wants the beautiful crest ; the upper parts 
are of a golden green, but less shining, and the under 
parts, instead of the fine azure, are of a clear gray. 
The white auriculars and spots on the outer tail 
feathers are, however nearly as conspicuous as in 
the other sex. 
From this species, and another lately discovered, 
having the lengthened crest of a lilac colour, Mr 
Lodiges proposes to form a genus Cephalepis. The 
lilac-crested bird is from the Rio Grande, and has 
been dedicated to Mr Lodiges.
