Adult Male—The band of velvety feathers on nape reddish- 
brown ; long hackles of neck, mantle, and chest with white 
middles, edged with black and margined with cobalt-blue ; 
breast and belly cobalt-blue, black down the middle ; sides 
and flanks washed with purple; rest of plumage mostly black, 
minutely dotted and spotted with white. Naked parts of head 
and neck cobalt-blue. ‘Total length, 30 inches ; wing, 12°2; 
tail, 11°3; tarsus, 4°1; middle toe (with claw), 3. 
Adult Female.—Differs only in having no knob-like spurs on 
the tarsi, and in being rather smaller than the male. 
Range.—Izast Africa, extending from the Pangani River 
northwards to Somali-land and westwards to Kilimanjaro. 
Although this remarkably handsome species was first 
discovered in 1834, practically nothing is known regarding its 
habits. Mr. H. C. V. Hunter, who met with it along the Useri 
River, tells us that it frequents dry red soil covered with thorny 
bushes; he also found it particularly plentiful on the Tana 
River, where, with the exception of the curly crested form 
(Guttera pucherant), it was the only Guinea-Fowl observed. 
Eggs.—An egg laid in the Gardens of the Zoological Society
