60 Col. R. Meinertzbagen on Birds from [Ibis, 



excluded from the above all birds belonging to the well- 

 defined races interstinchii^ [=■ satnratus), jaf onicus, and carlo. 



The paler birds with whitish under parts occur in northern 

 China (Aug.), throughout t*ersia and Baluchistan from 

 March to August, as winter visitors to Egypt, Kenya 

 Colony, :ind the Sudan, in Mongolia (May), throughout 

 Russia in summer; they breed in Palestine and Crete, occur 

 at Eregli in Asia Minor in winter, in central Asia in winter 

 and summer, and in Algeria and Morocco in winter and 

 summer. They are resident in Cyprus and the British 

 Islands, and occur in winter in Nigeria, India, and southern 

 China. Most birds from continental Europe and Asia 

 belong to this pale form. 



Breeding birds of the richly-coloured race occur in Egypt, 

 Nubia, Palestine, Crete, Morocco and Algeria, whilst I have 

 examined breeding birds of the paler race from Persia, 

 Mongolia. Italy, southern Russia, Palestine, (-rete, Bokhara, 

 Algeria, and the British Islands. 



On wiiiii' measurement, birds I'rom the Mediterranean 

 are smaller, but this is not constant within any definite 

 locality except Egypt. Also birds from the far north and 

 eastern Asia are slightly larger, but this again is not 

 constant. As the colour charactei'istic is also constant in 

 Egypt, I c;in only recognize two races of Falco tinnun- 

 culiis in Pala3arctic Europe and Asia (excepting japonicus), 

 though perhaps with a larger series of breeding birds from 

 the Mediterranean Region, a sufficient constancy of richer 

 coloration and smaller size might be found to justify a 

 further separation.
