Dr. Otto von Wettsteiu h;is also described a race (Voni 

 Kordofan (Anz. k. Akad. Wien, 1916, no. 13, p. 131) 

 which from the description dof^s not appear to differ from 

 /^. c. schubotzi ] but we have no examples from that region, 

 and it may be quite a valid subspecies.

This bird is recorded by Heuglin (Orn. N.O.-Afr. p. 76v*) 

 from Khartoum and the Blue Nile. We have seen no 

 Sudanese examples of this bird, and Mr. Butler never met 

 witii it. It is distinguished from the P. chrysoconus group 

 by its red forehead and more reddish rump, and is repre- 

 sented in the Museum by specimens from Abyssinia and 

 Somaliland.
