This form appears to be fairly distinet from typical 
P. domesticus, and a large series of specimens from the 
White Nile are quite alike as regards coloration. Captain 
Shelley has followed Dr. Sharpe in the ‘ Catalogue of Birds’ 
and regards the present form as inseparable from P. domes- 
ticus, but I agree with Dr. Reichenow in thinking that it 
should be kept distinct.
