what one observes in many cases, that a fairly widespread form suddenly splits 

 Up into a number of closely situated local races ; it must, however, be stated, 

 that specimens of Mirafra africana have not been compared from many parts 

 of Africa where it is likely to occur, and that therefore the ranges of several 

 forms may have to be extended considerablyj and even more forms may stiU 

 be discovered.

(Of the very rare Mirafra gilletti Sharpe we have a male, collected by Dr. 

 Donaldson Smith at Ahdeh, West Somaliland, 14. vii. 1894. This is actually 

 one of the cotypes of Sharpe, though he omitted to mention it, like several other

I do not now believe that H. m. giffardi is really different from H. modesta, 

 but the material at my disposal is so poor, that I would invite further investigation 

 before finally deciding the question. The two specimens collected by Giffard 

 are certainly lighter than those from Emin Pasha.
