indicus. Adult female very similar to indicus but cheeks darker and 

 greyer. 



Remarks. — Hartert (Vogel der Palaarktischen Fauna, Vol. I, p. 151), 

 left this lower Nile race without a name, his material being insufficient, 

 but in a footnote in the list of species to the first volume he refers the 

 Egyptian bird to niloticus of Nicoll & Bonhote (Bull. B. < >. club. XXII, 

 P. 101). 



P. d. niloticus is apparently a local desert race closely resembling 

 P. d. arboreus from Khartoum, and not the typical sparrow of lower 

 Egypt, which Nicoll & Bonhote still refer to P. d. indicus.
