In naming these birds I have examined the whole series 

 of this Kingfisher in the National Collection, and I have 

 come to the following conclusions in regard to the races : — 



Halcyon leucocephala leucocephala P. L. S. Miill. 

 op. cit. 



Of this, H. I. centralis Neum. (Journ. fiir Orn. 1905, 

 p. 189 : Bussissi, Victoria Nyanza) becoraes a synonym, 

 as also Halcyon rufiventer Sw. (Birds W^. Afr. vol. ii. 1837, 

 p. 101 : Senegal). 



Belly dark ; wings and tail pure cobalt. 



Female darker on the head, blue more greenish than in 

 the male. 



Ra7ige. Senegal, south to Cameroon, east to N.E. and 

 E. Africa, south to German East Africa. There are in the 

 Museum four specimens from Ruvvenzori, where it evidently 

 overlaps H. I. ogilviei. 



Halcyon leucocephala semic^rulea. 

 Alcedo semiccerulea Gmel. Syst. Nat. i. 1788, p. 457 : 

 Yemen, Arabia.
