496 BIRDS OF INDIA. 



In this genus the sexes differ in plumage, the males being more 

 uniformly colored, and the females more or less spotted or barred. 

 They are found both in Asia and Africa, one or two species being 

 occasionally killed in the South of Europe. These are the birds 

 termed Rock-pigeons by sportsmen in India. Blyth* retains for 

 them the popular name of ' GangaJ given them originally by Buffon, 

 but it is by no means generally known, and I prefer calling them 

 Rock or Sand-grouse, albeit not very closely related to the true 

 Grouse. 



They sub-divide into two groups, the one with the tail-feathers 

 regularly graduated, restricted Pterocles, apud Bonaparte; the other 

 with the medial rectrices lengthened and attenuated, Pteroclurus, 

 Bonaparte.
