western Kordofan in November 1902 by Major W. H. 

 Dunn. It bears a remarkable superficial resemblance to 

 Mirafra cordofanica, wbich occurs at the same place. It is 

 not represented in the present collections.

The birds from Omdurman are less leaden and more 

 reddish in tone above and below, and we thought at one 

 time they mi^ht be worthy of subspecific distinction ; but 

 similar birds are to be found in the large series of the 

 Larks at Tring from certain spots in the Algerian Sahara, 

 and there seems to be hardly sufficient grounds for 

 separation. 



As the light-coloured group of these Larks is very distinct 

 from the Indian A. phcenicitra, we prefer to place them as 

 subspecies of A. cinctura, the form from the Cape Verde 

 Islands. 



We recognize the following : — 



Ammomanes cinctura cinctura (Gould) : Cape Verde Is. 

 A. c. arenicolor (Sund.) : Algerian Sahara and Tunis to 



Palestine and the Nile valley. 

 A. c. pallens Le Roi, apparently confined to the Bayuda 



desert, north of Khartoum. 

 A. c. zarudnyi (Hartert) : Persia and Baluchistan. 



Ammomanes cinctura pallens. 



Ammomanes pho'nicura i^allens Le Roi, O. M. xx. 1912, 

 p. 6. 



There is a single example of this form in the Tring 

 Museum, obtained by Dr. Koenig in the Bayuda desert 

 north of Khartoum. 



It is smaller and paler than A. c. arenicolor.
