606 Messrs. Sclater and Maokworth-Praed on [Ibis, 



is a dimorphism of the northern races of M. cheniana, 

 although it is often slightly larger than the lighter-coloured 

 form ? On the material before us, however, we cannot do 

 otherwise than regard M. albicauda as a distinct species.

The type was from Kordofan. The l)irds from Balir el 

 Gliazal are distinctly darker than those in the Museum 

 from the Gold Coast hinterland and northein Nigeria, as 

 well as from a single old specimen said to be from Kordofan. 

 If they turn out to be sufficiently distinct, they can be 

 called P. e. infuscata (Heuglin, J. f. O. 1804, p. 273).
