[Irides brown ; bill black, one having the base mottled 

 ■with white ; legs and toes greyish black or dark grey. Two 

 or three pairs seen.] 



Reichenow in the ' Vog. Af rikas,' vol. ii. 1902, p. 123, 

 has suggested that Pogonorhynchus albicauda Shelley (Ibis, 

 1881, p. 117: Ugogo, German East Africa) and Melano- 

 hucco abbotti Richm. (Auk, 1897, p. 164 : Taveta, British East 

 Africa) are merely stages of plumage of Po^onor Ay wcAMj?se/2«.« 

 Beicliw. (Journ. fiir Orn. 1887, p. 59 : Ikanga in Ukamba), 

 the last-named being the full adult. I agree that the evidence 

 points to that conclusion being correct, and moreover con- 

 sider that a much larger series will show that L. leucocephalus 

 is L. senex in its first dress. Should this prove correct, 

 L. leucocephalus as the oldest name would stand for the 

 species. Until this question is finally settled, the status of 

 Lybius leucocephalus usukuma Neum, (Bull. B. O. C. vol. xxi. 

 1908, p. 46 : Kagehi, Usukuma, north-west German East 

 Africa) cannot be defined. Pogonorhynchus leucogaster 

 Bocage (.lorn. Acad. Real Lisboa, 1877, p. 63 : Quillen- 

 gues, Benguela) is allied to the above and appears to 

 differ only in having the under wing-coverts pure white; 

 but I have not been able to examine specimens from 

 Angola. 



192. Lybius tridactylus. Red-headed Barbet. 



Loxia tridactyla Gmelin, Syst. Nat. i. pt. 2, 1789, p. 866: 

 Abyssinia. 



a, b. S ad. Kamchuru, 3200 & 3250 ft. Feb. 10 & 12. 



Total length in flesh : 7 inches. Wing : 85 & 82 mm. 



Both these specimens are showing signs of wear. 



[Irides brown ; bill, legs, and toes black. This con- 

 spicuous bird is tolerably common.] 



Phytotoma abyssinica Lath. (lud. Orn. Suppl. i. 1801, 

 p. xlix : Abyssinia) is a synonym, and I also place as a 

 synonym Lybius tridactylus ugandce. (Berger, Orn. Mouatsb. 

 1907, p. 201 : Nimule, Uganda, wing given as 78 mm.), 

 as the characters given do not appear to be substantiated 

 by the good series in the British Museum collection.
