Adult. Easily distinguished from N. coronata by the shape of the 

 bony helmet, which is less than half the breadth and nearly cylin- 

 drical ; only a few feathers below the naked neck show traces of 

 bars, and the white spots are continuous over the whole plumage ; 

 but this character is not of much importance, for in the type 

 specimen of N. coronata the bars at the base of the neck are broken 

 iuto irregular spots. Naked skin of face clear blue ; helmet vermi- 

 lion ; naked part of the neck purplish blue, wattles the same, scarlet 

 at the extremity. Total length 21-.5 iuches, wing lU-4, tail 5 8, 

 tarsus 2-7, middle toe (with claw) 2-4.
