An examination of the series of the Paradise-Wliydahs in 

 the British Museum shows that birds from the southern 

 half of Africa, including Nyasalaud, Uganda, and Belgian 

 Congo, are larger than those of the northern part of the 

 range, including noi'th-west and north-east Africa. 



The wings of the adult males of the southern race average 

 85 mm. and are seldom below 80 ; those of the northern 

 race average 78 mm. and are rarely above 80. As this seems 

 to be fairly constant, it seems worth while to distinguish 

 the two raceii. 



Tiie oldest name for the northern race appears to be the 

 one here adopted. The wing of the male of the type 

 measured by Cassin is given as 3"1 inches, which is just 

 under 80 mm. The other distinctions given by Cassin do 

 not seem to liold good, and he is mistaken in stating that it 

 is a generally larger bird. 



Birds from Senegambia have been separated by Neumann 

 (Bull. B. O. C. xxi. p. 43) as S. p. aucupum, and are distin- 

 guished l)y the dark colour of the neck. From the limited 

 material available in the Museum this would appear to be 

 constant, but occasional birds from other parts of Africa are 

 quite as richly coloured.

The adult male comes nearest to A. macmillani Bannerman 

 (RiiU. B. O. C. xxix. 1911, p. 38), but is distinctly smaller 

 (wing averages 66 mm. against 72 mm.) and has only traces 

 of golden yellow about the forehead, the crown being washed 

 M'ith greenish brown ; the back has somewhat broader stripes 

 of brown and the feathers have a paler almost whitysh edging 

 (not greenish as in A. macmillani). The sides of the face and 

 cheeks are also washed with brown, and are not so yellow as 

 in the other form. The lower surface is a paler yellow than
