 pternistes. 



Pteruistes, Wagler, Isis, 1832, p. 1229. 

 Type, P. nudicollis (Bodd.). 

 The characters which distinguish this genus are the same as 

 those of Francolinus, but the throat is naked, and the naked 

 patch round the eye is large and conspicuous. 



The nine species comprising this genus may be divided into 

 two sections : — 



A. Feathers of the back and scapulars with dark-brown or 

 black shaft-stripes (species i to 7, pp. 136-140). 



B. Feathers of the back and scapulars with white shaft- 

 stripes (species 8 and 9, pp. 140- [41).
