In the series in the British Museum there seem to be the follow- 

 ing recognizable types of plumage : — 



A. Occipital tufts and ruff uniform white ; head white ; back 



powdered with grey ; breast-plumes black. 



B. Occipital tufts black ; ruff uniform white • head greenish black 



like the ruff ; back purplish black ; breast-plumes black. A 

 variation of this type exhibits faint frecklings of black on 

 the ruff, with a little black on the throat. 



C. Bufous type. Buff uniform white ; crown of head and occi- 



pital tufts rufous, which is the general tone of the upper 

 surface ; breast-feathers rufous, with rather broad black bars. 



D. Buff uniform, purplish blade ; breast- feathers also black. 

 The tufts on the hinder crown vary, and generally assimilate 



in colour to the crown, which may be black, white, rufous, 

 or sandy buff, the latter with an admixture of blue-black. 



E. Buff uniform, orange-bvff, or chestnut. In the former the 



occipital tufts and crown are blue-black or purplish black, 

 like the back itself. 

 In the more chestnut specimens, the occipital tufts and crown 

 are greenish black, and the back purplish black. On some 

 of the feathers of the throat are occasionally powderings or 

 spots of black. 

 All the following types have the rvff er neck-sJiield barred : — 



F. Buff glossy greenish black, with narrow rufous lines ; occi- 



pital tufts greenish black like the crown ; back purplish black. 



G. Buff rufous, scantily barred with blue-black ; crown of head 



and occipital tufts rufous ; back rufous, barred with purplish 

 black. 



H. Similar to the foregoing, but with the crown and occipital 

 tufts barred with purplish black ; breast-feathers rufous, 

 with purplish-black bars. 



I. Similar to the foregoing, but with greenish-black crown and 

 occipital tufts ; breast-feathers purplish black. 



K. Buff barred with sandy buff and purplish black in about 

 equal proportions, the bars being of about the same width. 

 The head and occipital tufts of the same pattern as the ruff, 

 or purplish black. In the latter case the breast-feathers 

 are black, but in the former type they are rufous, with 

 bars or spots of purplish black. 



L. Buff buffy white, regularly barred with purplish black, the 

 breast-feathers being similarly marked ; occipital tufts buffy 

 white, with black bars ; the head streaked with black. 



M. Buff buffy white, sub-terminally spotted or barred with 

 purplish black, before which is a tawny bar; the head and 

 occipital tufts of the same character ; breast- feathers tawny 

 buff, with black semicircular bars near the ends. 

 The head and occipital tufts in this light-coloured type are some- 

 times vermiculated like the back, or are pale cinnamon like 

 the rest of. the upper parts.
