 was done by Oberholser, P. U.S. Nat, Mas. xxviii, 1905, p. 843.

There appear to be more races than one of this species, 

 but again we are held up by having no material from any- 

 where near the type-locality — if Senegal really was the 

 type-locality. 



The birds before us seem to group themselves into 

 possibly three races : firstly, a paler race from Fgypt ; 

 secondly, a rufous race from southern Tripoli, Fezzan 

 through the Sudan to Somaliland ; and, thirdly, the Indian 

 birds, which are more like the Egyptian form, but with a 

 noticeably blue flush on the hind-neck of the males. A 

 possible name for the Sudanese form would be P. s. guttatus 

 {Pterocles guttatus Licht. Verz. Doubl. 1823, p. 64, ex 

 desertis Nubise). The examination of further material, 

 however, has made us very doubtful whether any races can 

 really be separated.
