Birds from British East Africa and Uganda. 267 



This race forms a link between H. I. swainsoni and H. I. 

 leucocephala. The sexes do not differ. 



Range. Nyasaland, through the lake districts to E,u- 

 wenzori. Two specimens from Ruwenzori in the British 

 Museum collection. 



138. Halcyon senegalensis cyanoleuca. Angola Kingfisher. 



Alcedo cyanoleuca V^ieill. N. D. d'Hist. Nat. vol. xix. 

 1818, p. 401 : Angola. 



a. c? ad. Amala River, 5300 ft. Oct. 23. 



In fresh new plumage, the wings being still in moult, and 

 having the top of the head washed with blue. 



Total length in flesh : 9^ inches. Wing : 106 mm. 



[Irides brown ; bill : upper mandible red, lower black ; 

 legs and toes black. Stomach contained fish and frogs.] 



In naming this specimen I have had to examine the whole 

 series of this Kingfisher in the National Collection, and I 

 have come to the conclusion that this race and H. s. sene- 

 galensis occur together at least for part of their range, but 

 until a larger series of carefully sexed specimens is available, 

 and especially of young birds from the nest with the actual 

 parents belonging to them, no definite conclusion can be 

 come to. 



Since the publication of ray description of H. s. superjlua 

 (Bull. B. O. C. XXXV. 1914, p. 28) Mr. Ogilvie-Graut has 

 kindly pointed out to me that Vieillot, in his original de- 

 scription, gives *' la tete, le dessus du cou, le dos, les ailes et 

 la queue sont d'un bleu d'aigue-marine,^^ and that, tlierefore, 

 this new subspecies must become a synonym of " cyano- 

 leuca " : with this conclusion I am inclined to agree. 



The evidence before me points to the one race being con- 

 fined to the south and extending into east Africa, and the 

 other confined to the north-west and also occurring in east 

 Africa, where many specimens bear the characters of both, 

 which might be expected where subspecies overlap. The 

 southern bird does not, however, in my opinion, meet with 

 the north-western form throughout its range.
