the tint on the cheeks is different; the belly and under wing-coverts 
are green; the primaries are not edged with blue; the centre tail- 
feathers are only blue for half their length ; and the rump is green.

The pair of birds from which the accompanying descriptions and 
figures were taken, are now living in his lordship s aviaries. A new 
and beautiful species of a limited family like the Curassows must be 
looked upon as a valuable addition to our stock of ornithological 
acquaintances, and deserving of a distinguished cognomen. I there¬ 
fore propose to name it after Her Most Gracious Majesty’s illustrious 
consort, His Boyal Highness Prince Albert, forming at the same time 
a companion to my Goura Victoria. 
The male is at once distinguished from its nearest ally ( Crax Alec- 
tor , Linn.) by the blue cere: the female differs from all the speci¬ 
mens I have had an opportunity of examining by the broad bands on 
the tail. 
Penelope niger. (Aves, PI. XXIX.) 
Male : Black, with blue, and in some lights green reflections ; bill, 
throat (nearly naked), tarsi and feet red. 
Female : Brown, with green reflections, each feather having several 
bars of rust-colour, the colour and markings being less distinct on the 
under surface of the bird. 
Length from base of beak to tip of tail, 23 inches.
