106 Mr. C. W. Mackwortli-Praed on [Ibis, 



cases, only those from which I have actually examined 

 specimens. 



In Grame-Birds such as Francolins, with but short powers 

 of flight, quite small natural features may be hard and fast 

 boundaries; and this naturally leads to the multiplication of 

 racial forms. I have described some few of the most dis- 

 tinct of those which had not been recognised in the Bull. 

 B. 0. C. 1920 and elsewhere, but a large number I have 

 merely indicated in this paper. I consider it very desirable 

 that not only should a representiitive series be at hand before 

 a race is named, but also that some knowledge of its range 

 should be obtained. 



I have left all the African Francolins in one genus, 

 though I do not consider it by any means the most correct 

 arrangement, nor must the order in which the species are 

 taken in this paper be considered as reflecting any opinion 

 as to their relationship. Francolins are not easy birds to 

 collect, as the services of a dog are not usually available, and 

 moreover, when secured they too frequently go straight into 

 the pot. This may account for the fact that several species 

 are known either from a single specimen, or have not been 

 met with since their first discovery. 



The measurements in all cases are in millimetres.
