W e have named this species in honour of the distinguished naturalist who 

 first characterised the genus. It is, like the preceding one, furnished with 

 a broad cartilaginous wattle arising from the upper eye-lids, which is of a 

 bright scarlet-red, and apppears to have lost very little of its original colour. 

 The length is four inches and a half : the head, neck, and back, are blackish- 

 grey ; the wings and tail are bluish-black, and have the same white markings 

 as in P. collaris ; the throat is white ; the neck and upper part of the breast 

 are deep reddish-brown, which terminates in a crescent form on the breast, and 

 is there edged with deep bluish-black ; the lower part of the breast, belly and 

 vent are white ; the legs and feet are bluish-black.
