The Arabian Rock-Dove is very close to the Indian form, 

 with the grey rump tlie same colour as the back. It is also 

 very similar to the Egyptian bird, which has been called 

 Columba schimperi. But, as has been recently shown by 

 Mr. Stuart Baker, the Rock-Dove is so often kept in a 

 state of domestication or semi-domestication and the true 

 wild birds so often cross with the domesticated ones, that it 

 is most difficult to arrange the forms into distinct geogra- 

 phical races, and Mr. Baker himself is in favour of treating 

 all the grey-rumped Rock-Doves from Tunis to China as one 

 race. If this is the correct view the Yemen Rock-Doves 

 must cert linly be called 6'. livia intermedia.

The Arabian examples of Lichtenstein's Sand-Grouse are 

 undoubtedly paler than those from Nubia and north-east 

 Africa, and seem worthy of subspecific distinction, as has been 

 pointed out by Neumann and Claude Grant.
