Among the birds collected by Messrs. Chapman & Lynes 

 are several young examples in the spotted plumage ; they 

 differ from the adults in having the shoulders and wing- 

 coverts spotted with rufous, and the tips of the primaries 

 and secondaries and the edges of the latter edged with 

 rufous ; below, the edges of the breast-feathers are dusky, 

 forming crescentic marks. 



There are examples of this species in the Museum from 

 the Sobat river and other localities on the White Nile, but 

 not from Abyssinia whence the type is said to have come. 

 On the other hand, Gl^. botta, its larger representative, seems 

 to be confined to the higher elevations of the Abyssinian 

 plateau, and we doubt its occurrence in Sennar as recorded 

 by Heuglin.
