Ptyonoprogne obsoleta obsoleta (Cab.). 



The Pallid Craii-Martiii is found in winter in all the 

 foot-hills and in the hills themselves ol the Khirthar from 

 the north to Cape Monzc. Into the plains near the foot- 

 hills it straggles in small numbers in some years, fre- 

 quenting well-sheltered spots. It is quite likely that this 

 species moves but altitudinally in Sind and breeds in the 

 Khirthar ; the lower hills I have searched during the 

 summer in vain. In the Soorjana pass I have seen them 

 iioino- to roost in winter in holes and crevices in the cliff 

 often quite low down near the water's edge. 



Eight males : wing 116-125; twelve females : w^ing 116- 

 123 mm. These do not diifer in size from Egyptian birds. 

 Some Egyptian birds are paler than those I have seen from 

 Sind, but are however more worn in plumage ; by far the 

 palest bird of a series comes from Fao ; wear makes a con- 

 siderable difference in })aleness, and as some Egyptian birds 

 do not differ at all from Sind ones, I consider that both 

 belono- to the same race. 



Hirundo rustica rustica L. 



The Common Swallow is abundant as a winter visitor and 

 its distribution' is entirely dependent on water^ away from 

 which only odd birds are met with. It arrives in Upper 

 Sind early in August in numbers and lingers some time in 

 that comparatively well watered part as only stragglers 

 have reached Lower Sind by then, and it is not till Septem- 

 ber^ and in very dry years the end of October, that they 

 become numerous in the latter district. Most disapjiear again 

 in March and few may be seen throughout April, possibly 

 passage migrants from elsewhere ; I have seen single birds 

 on 2 and 26 May and 6 June. I have no evidence that it 

 breeds in Sind ; it breeds on theiMekran coast and of course 

 in Quetta. In January both young of previous year and 

 adults start a complete moult which is finished ere they 

 depart.
