328 BIEDS OF EGTPT. 



Fam. PodicipiDjI;. — Podiceps nigricollis, P, griseigena, and 

 Colymhus septentrionalis are included upon Von Heuglin's 

 authority. 



With the exception of some two or three species of which 

 I have seen undoubted Egyptian specimens, all the remaining 

 birds included in the present work have been collected by 

 myself in that country.
