amber yellow (in ail the three spécimens which are now in the 

 Berlin Muséum). Nearly the whole upper-side of C. fischeri is 

 blackish olive-brown. There is no gloss on the black head. The 

 under wing-coverts are more reddish than in any of the races of 

 C. monachus. The yellowish bufl eve-streak is another verv pro- 

 minent character of C. fischeri. » 



It appears, therefore, that \ve must revise our material in the 

 British Muséum and in ail probability the Sudan birds will hâve to 

 bear Neumann's name C. heiiglini while the Cameroon Mountain 

 birds must be assigned to the race C. m. occidentalis which Grant 

 discarded. 



We shall therefore be left with : 



1 . — Centropus monachus monachus. 



Centropus monachus Riipp., Neue Wirb., 1835, p. 57 : Kulla, 

 N. Abvssinia. 



Raiis^e. — Abvssinia and North Kenva Golonv. 



2. — Centropus monachus heuglini. 



Centropus //eng/int Nevm., Verh. V. Intern. Orn. Kongr, 191 1, 

 p. 504 : Bahr-el-Ghazal. 



Range. — Sudan and White Nile District. 



Observation. — If this race is not accepted the Sudan birds must 

 be called occidentalis and not fischeri ! 



3. — Centropus monachus occidentalis. 



Cf. supra. 



Range. — Gold Coast, Freiich Equatorial Africa, Northern and 

 Southern Nigeria, Cameroon, Gaboon, North Belgian Congo 

 eastwards to Kenva Colony (Elgon) and Uganda (Entebbe).
