Both species of Herring-Gulls are occasionally seen on the 
river at Giza, as well as on the flooded country. At a distance 
it is not always possible to distinguish them, especially as 
L. cachinnans is often as light on the mantle as L . argentatus , 
but I have at times positively identified both forms.

The Lesser Black-backed Gull is frequently met with 
from autumn to late spring.

On February 14th, 1908, I saw a Grebe, which I believe 
to have been of this species, on a pool close to the railway 
between Cairo aud Helwan. 
Since the publication of the first part of this paper a 
certain amount of additional information has come to hand, 
and examples of several species not included in it have 
been obtained by myself or my friends in the Province of 
Giza. A few corrections in nomenclature are also advisable. 
During June last I was enabled, by the kind permission of 
the Hon. W. Rothschild and Dr. E. Hartert, to compare the 
majority of my birds with the fine and well-caredd:or 
collection in the Tring Museum, and thus had the oppor, 
tunity of comparing several of my skins with the types in 
the Brehm collection. For this privilege, and also for their 
kind help in identifying many birds which I have been 
unable to examine personally, I wish to record my best 
thanks to Mr. Rothschild and Dr. Hartert. My best thanks 
are also due to Dr. Sharpe and Mr. Ogilvie-Grant, who have 
given me much help while working at my collections in the 
British Museum. 
With the Editors’ permission, I hope, at some future time, 
to write an Appendix to the Birds of Giza, and thus bring 
the list “ up to date ” as far as possible.
