Adult. This form seems to represent D. major in the south- 

 western parts of Africa. All the specimens from Benguela and 

 Angola are very similar to D. major, bnt differ from this species in 

 the following- points: — (1) The fluffy feathers of the rump have very 

 large pure white tips, which together form a cospicuous white patch 

 on the sides of the rump ; the fluffy feathers of the lower back have 

 subterminal white spots, but rather broad black tips, as in D. major. 

 (2) In almost all the southern specimens there are three of the secon- 

 daries externally edged with white, though the specimen described 

 by Hartlaub as the type has only two secondaries edged with white ; 

 whole under surface of body pure white. 



Obs. The typical specimen is not fidly grown, as is shown by the 

 state of the quills.

Hab. S.W. Africa: Congo and Angola as far as Damara Land, 

 and eastwards to Lake N'gami. 



Obs. One fully-grown male specimen from the Cunene river and 

 another from Lake N'gami have the two feathers of the outermost 

 pair of the tail-feathers just tipped with white. Of two others, 

 however, collected by Dr. Bradshaw near the Zambesi, one has the 

 outer pair of tail-feathers slightly, the other one conspicuously edged 

 with white on the outer webs.
