THE HELMETED GUINEA-FOWLS. 87 



on the hind-neck, tliat of tlic lower-neck milky-white. Total 

 length, 19 inches; wing, 87; tail, 6; tarsus, 2*9. 



Adult Female. — Similar to the male, but devoid of spurs, 

 Range — West Africa, from Liberia to Gaboon. 

 Like the Black Guinea-Fowl, this is one of the rarest birds 

 in European collections, and up to the present time nothing is 

 known regarding its habits. Mr. Biittikofer obtained several 

 examples during his expeditions to Liberia, but these were 

 bought from natives, who trap them in the bush-paths. Accord- 

 ing to native report, the Turkey-like Guinea-Fowl, though well- 

 known, is very rare everywhere.
